2 Construction of Farmland Solar Radiation DB Using GIS to Solve the Problem of Abandoned Cultivated Land and Select Cultivated Crops for AI , Atsushi Shiota, Thongchart Kerdphol and Yasunori Mitani
In Japan, abandoned cultivated lands have increased due to labor shortages caused by aging, low productivity, lack of farmland recipients, and poor land conditions. The increase of abandoned agriculture land causes problems such as a decline in the multifunctionality of agriculture, the occurrence of pests, birds, and animals. For this reason, the Japanese government has enacted legislation considering the measures to reduce or prevent the abandoned agricultural land. As a result, the area of abandoned agriculture lands was 423,000 ha in 2015, and the rate of increase has slowed.On the other hand, there is RUE (Radiation Use Efficiency) as a numerical value, representing the relationship between the amount of crop production and the amount of solar radiation. RUE is obtained by dividing the dry matter production amount by the accumulated light reception amount during the same period, and it is known that the dry matter production amount increases as the accumulated light reception amount increases, although there is a difference depending on the crop. Our research team has constructed a solar radiation simulation system using GIS (Geographic Information System) and DSM (Digital Surface Model) considering the shadow of buildings and trees. As a result, it has become possible to support the selection of a place, where the amount of solar radiation falling on the solar power generation system can be efficiently obtained, and to understand how much solar radiation can be obtained when the solar power generation system is installed. In addition, it has been incorporated with the weather conditions into this simulation system. Finally, a solar radiation simulation considering the weather conditions is successfully built.Based on these circumstances, this research focuses on the amount of solar radiation falling on farmland, and constructs a farm-land solar radiation DB in consideration of the shadow of buildings and trees and weather conditions for each farmland. The purpose of this research is to visualize farmlands that can receive a large amount of solar radiation and to establish a mechanism to support prioritization during the selecting abandoned agriculture lands and supporting the reuse of abandoned agriculture lands. In addition, the farmland solar radiation DB is designed to build an farmland DB that can manage items such as precipitation, temperature and soil in addition to solar radiation, assuming a mechanism to be able to propose crops grown using AI(Artificial Intelligence) in the future
3 Efficacy of Compatibility between Endophytic Biocontrol Agents and Abiotic Agents as Fungicides Alternatives for Controlling Root Rot of Grapevine , El-Sayed Hussein Ziedan, Moataza Mahmoud Saad, Mohamed Abd-El-All El-Naggar, Khames Ahmed Hemida, Magdy Gad El-Rab El Samman and Mostafa Helmy Mostafa
Root rot of grapevine an epidemic disease causing by several soil borne fungi recorded high loss plant growth of productivity. Nine endophytic biocontrol fungal and bacterial isolates of Trichoderma spp, Bacillus spp and Pseudomonasfluorescens were tested against growth of aggressive fungal isolates causing root rot of grapevine i.e. Fusarium spp. and Botryodiplodia theobromae. Results showed that the best antagonistic endophytic isolates were Trichoderma harzianum and Bacillus subtilis. Trichoderma harzianum isolate sig-nificantly reduced mycelial linear growth and conidial sporulation of fungi tested as well as over lapping growth of fungi tested. In addition, Bacillus subtilis recorded high zone inhibition toward all pathogenic fungi tested than another bacterial isolates in this study. Some promising essential oils, organic, antioxidants acids and their combinations were tested on growth of endophytic biocontrol agents of Trichoderma harzianum and Bacillus subtilis. Results obtained indicated that sorbic acid followed by propionic acid were the least effect on mycelial linear growth and conidial sporulation of Trichoderma harzianum. In addition, sorbic acid, propionic acid (0.1%), black seed oil (4.0%) and their combination had no effect negatively on Bacillus subtilis growth. In greenhouse experiment soil drench by propionic + sorbic acids, propionic acid + sorbic acid + T. harzianum + B. subtilis were the best and significantly treat-ments its completely suppress (100%) root rot disease percentage and disease severity on shoots and roots of grapevine plants fol-lowed by T. harzianum as individual or combination with B. subtilis were increased morphological characters of grapevine plant i.e. length, fresh and dry weight of and root size. So, combined soil treatment by propionic acid + sorbic acid or propionic acid + sorbic acid + T. harzianum + B. subtilis as the safe fungicide alternatives for management root rot disease of grapevine
4 The Harmony of the Physical Vacuum , Anatolii Pavlenko
This paper is a summary of ideas and methods related to protection of people from the negative impact of electronic technology. While conducting research, the author intended to clearly define the prevailing negative impact of torsion fields in comparison with electromagnetic radiation. Electromagnetic fields warm the tissues of a person using all sorts of gadgets, while torsion fields provide influence at the gene level. Much attention is paid to the technology of protection from torsion fields. For a more complete under-standing of the problem of protecting the population from the negative influence of torsion fields, the authors considered the concept of the “fabric of the universe” developed by several authors, which enabled representing the processes occurring in Physical Vacuum in a more distinct way. The fact that virtual particles have their own subconscious nature, which differs from ours that was predicted by N. Tesla, has been confirmed
5 First Report of Cophinforma atrovirens and Trichoderma ghanense Associated with Inflorescence Dieback of Cashew and Soil in Nigeria , Dele Omoyele Adeniyi, David Adedayo Animasaun, Olusola Thomas Oduoye and Ramar Krishnamurthy
Cashew tree (Anacardium occidentale L.) is a plant of great economic value not only to growers but other players in the val-ue chain. The crop is mostly cultivated for the nut and can thrive in many agro-ecologies of Nigeria. A case study survey of major cashew plantations and soils of major growing areas in North Central, Nigeria comprising of Oro (Kwara State) and Ejule (Kogi States) showed typical symptom of dieback on cashew panicles re-corded in around 35% and 45% of established cashew trees in the plantations respectively. This disease situation typically referred to as inflorescence dieback of cashew in Nigeria, and this also oc-cur on cashew seedlings both in the nursery and newly established fields. This disease condition and incidence has earlier been as-sociated with Lasiodiplodia species, while the isolated fungi from the soil have priorly been classify as Trichoderma harzianum. The molecular study in this situation depicts the organisms as Cophin-forma atrovirens and Trichoderma ghanense respectively in which very close morphological resemblances were observed

10 Improving the Durability of Agricultural Machinery Parts by Applying Antifriction Coatings , Yakov Nemyrovskyi, Ihor Shepelenko and Olha Medvedieva
An analysis of the literature showed that the problem of increasing the durability of the friction parts of agricultural machinery (AGM) can be successfully solved by applying antifriction coatings on their surface. The analysis of the existing anti-friction coating application schemes showed that the most simple, resource-saving and environmentally friendly is the method of finishing anti-friction non-abrasive treatment (FANT). The possibility and feasibility of using FANT with respect to AGM friction units have been proved. To achieve higher performance properties of parts with anti-friction coatings, combined processing using FANT and deform-ing broaching is proposed. Using cylinder liners as an example, it is proved that the use of the proposed technology improves the working capacity and durability of rubbing parts of AGM, thereby increasing the life of tribo-joints of mobile AGM and can be recom-mended both in the manufacture and in the restoration of friction parts of mobile agricultural machines.
11 The Super Cyclonic Storm Amphan Inflicts Massive Damage to Coastal Aquaculture in Bangladesh , Shoaibe Hossain Talukder Shefat
The monstrous cyclone Amphan, formed in the Bay of Bengal was the strongest tropical cyclone affecting the Ganges delta after Sidr in 2007 that caused severe damage in India and Bangladesh in May 2020. It was also the first tropical cyclone in the North Indian Ocean in 2020. Originating from a low-pressure area in Colombo, Sri Lanka on 13 May 2020, Amphan reached its maximum intensity on 18 May that sustained for 4-minutes with a wind speed of 240 - 260 km/h (150 - 160 mph), and a minimum central barometric pressure (925 mbar) (Figure 1). However, the intensity gradually weakened by continuous and combined dry air and wind shear ef-fects and reached a residuum level on 21 May. During this period, Amphan caused severe destruction of more than US$13 billion in India and Bangladesh.
12 Chemical Variation of Essential Oils from Peels of Citrus kinokuni Tanaka, C. reticulata ‘Dahongpao’, and C. reticulata ‘Zhang Shuensis , Ting-Li Han, Inam Ullah, Jian Wang
The chemicals in essential oils from peels of three varieties of Citrus reticulata Blanco like C. kinokuni Tanaka (K), C. reticulata ‘Dahongpao’ (D) and C. reticulata ‘zhang shuensis’ (Z) were investigated by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-flame ionization detector (GC-FID), respectively. A total of 97 compounds were quantified in which 80 components were identified and 17 unknown components were detected. The quantitation results of D and Z were profoundly different from previous studies due to the different treatment to peels. The different oil-types from K, D, and Z were high in β-myrcene, p-cymene, limonene, γ-terpinene, α-terpineol, thymol, (E, E)-α-farnesene, spathulenol and isospathulenol. The chemicals’ fluctuation in oils of D and Z was more pronounced than that of K. Principal component analysis (PCA) revealed the peel of K, D and Z could be classified as three kinds according to their chemical changeability, respectively, consisting with the usage of these peels in Chinese medicine. Lastly, the oils’ chemotypes of K, D, Z and other cultivars were analyzed, showing that the % variation of six characteristic components including limonene, γ-terpinene, methyl N-methylanthranilate, linalool, (E, E)-α-farnesene, and thymol, played an important role in discriminating oil-types from varieties of C. reticulata.

Olive trees can be grown in marginal areas and adapt to different climatic and soil conditions which is easier to grow than other plants. It has positive effect of olive oil for human health. Therefore, olive cultivation is increasing day by day with the modern of olive techniques and it is preferred to grow by farmers thanks to the positive effects of olive oil and olive. The study was carried out in Ayvalik olive fields in which have different altitudes, in order to examine the current status of olive cultivation in Manisa/Ahmetli area, to soil and leaf analyzes and nutritional status and to determine the suitable harvest periods on high altitude and low altitude in terms of olive and olive oil quality. The current status (age, education, land positions) of the olive farmers were determined by survey in the Manisa/Ahmetli area. Fruit samples were harvested during 4 different periods (10 October, 13 November, 23 November and 5 December). In fruit samples: fruit weight (g), maturity index, color (CIE L*, a*, b*), dry matter (%) were determined. Oil samples, free fatty acidity and fatty acid composition were determined on high altitude and low altitude.In conclusion soil and leaf analyzes indicated that there were nutrient deficiencies and recommendations were made about olive cultivation in olive farmers. The suitable harvest periods were determined of high altitude and low altitude in terms of olive and olive oil quality. In this research, suggestions were given about olive cultivation and it is provided to shed light on future studies
15 Precious Supply Chain Management of Onion (Allium cepa L) by Examining the Production, Quality Expansion and Market Analysis for Food Safety , Sidhartha Kar
Onion is an important and indispensable vegetable in kitchen as condiment and vegetable which captures an extensive internal as well as external market. The green leaves matured and immature bulbs are eaten raw or used in preparation of vegetables. It is used as salad and cooked in various ways, in all curries fries boiled or scorched onion. It is also used in processed form e.g. flakes, powder, paste, pickles and some seasoning foods. It is valued much on account of its characteristics pungency which is due to presence of sul-phur compound (Ally propyl disulphide). It possesses some important medicinal properties. The organic onion is flourishing mainly due to consumer choice. The organic onion is much preferred than traditionally grown. It makes an increase in varieties and selection of onion in retail, supermarket and restaurant. The market plays an important role in determining the pattern as well as the pace of diversification in favor of high-value crops like onion. An increase in production is of little value unless there is a good marketing system.Keeping the above view a research analysis on “Precious supply chain management of onion (Allium cepa l) by examining the pro-duction, quality expansion and market analysis for food safety” was carried out and found among two zones selected such as eastern coastal plateau zone and mid central table land zone, Mid central table land zone found most suitable for onion farming and fulfilling all most all farming requirements. Effect of organic nutrient and botanical pesticides on onion applied, the best onion varieties re-sponse to vermi compost (50%) that is 2 t/ha + NPK (50:50:50) 50 Kg each/ha was remarkable and best organic treatment. Effect of cultivation of different onion varieties found best results with onion variety Agri found Dark Red which has got best results in concern to growth and yield. Effect of integrated weed management on weed density, Dry matter weight of weeds and weed control efficiency found best results with weed control treatment one hand weeding at 20 Days After Transplanting + Ridge and furrow making (6” X 6”) length X breadth in onion variety N-53. Market survey found best results with variation within experimental period of time analysis found Bhubaneswar has lowest varia-tions of onion price from wholesale to retail sell price. And also experimental State have best control over onion price hike during the market research and experiment year that is survey results from year 2013 - 2017. Supply chain management models analyses it is concluded that onion SCM developed after survey that is a new model from research to different marketing channel partner involvement and then grass root label point coverage’s prepared and samples are tested in field found best results.E-Onion marketing and digitalization found a new and best technology to reduce marketing costs and examined during experi-ment founds best response among primary, secondary and tertiary stock holders.Among different onion farming treatments integrated organic onion production technology found best economic results in com-parison to conventional onion farming technology that is C:B = 1.97 (Cost Benefit ratio) and net returns are best with organic onion production technology that is Rs. 1,95,802/- (Rs/ha).
16 Soil Organic Fertilization in Long-Term Low-Input Cropping System and its Effect on the Bread Making Flour Properties Determined by Albumen-Protein Complex , Nankova Margarita, Doneva Sonya, Iliya Iliev and Stefan Krustev
The results of the study on the quality of flour of 20 wheat cultivars (Triticum aestivum L.) grown in a long-term low-input crop-ping system of Haplic Chernozems are reported. The cultivars were developed at Dobrudzha Agricultural Institute, General Toshevo. They were sown on two soil nutrition regimes: 1. Control - natural soil fertility and 2. Organic fertilization with ExcellOrga, produced in France. In addition to these variants we used a humine preparation Plantagra for pre-sowing seed treatment of sowing material (150 ml/100 kg seeds).Main soil organic fertilization with ExcellOrga especially in combination with seed material treatment (SMT) positively influenced on the sedimentation values and bread volume. The average value in this variant is 42.55 ml with increasing over control variant with 3.65%. The highest and relatively stable by variants were the sedimentation values of cultivar Pchelina (51.25 ml), followed by culti-vars Kiara (50.25 ml) and Galateya (46.75 ml). The bread volume in this condition exceeded the control with 3.75%. The maximum value in the trail was reached from cv. Bojana - 795 ml.Organic fertilization lead to increasing a wet gluten content according to the control with 2.60%. The cultivates Kiara and Bojana has a leader position according to the value of this index - 23.35% and 23.25% respectively. A tendency was established for decreas-ing of values of wet gluten content in variants with SMT. However, an exception to the tendency the genotypes specificity is strongly expressed - cultivars Pchelina, Kosara and Kiara reacted positively to the SMT.Flour stability is subject to highly expressed dynamics of values according to the genotype. Cultivars Enola and Katarjina were distinguished with maximum average values - 3.88 and 3.80. Soil organic fertilization increased values of this index according to the control variant with 4.60%. Valorimetric values were negatively influenced by soil organic fertilization and especially with combina-tion with SMT.We established also highly expressed correlations between yields (grain and protein) with chemical composition of grain, physical grain properties, rheological properties of flour and bread making qualities
17 The Development of Analytical Methodologies and Advances in Plant Physiology, Measurable Amounts of Elements in Nutrients Contribution and Carbon Assimilation by Five Grain Legumes, Bambara Groundnut; Groundnut, Cowpeas, Blackgram and Mungbeans Planted in Mpumalanga province, South Africa during 2011/2012 Season , MD Lengwati
A field experiment was carried out in the 2011/2012 summer cropping season at the Lowveld Research Station, Nelspruit (Bom-bela), in Mpumalanga province, where five grain legumes planted under field conditions during the planting season 2011 replicated four times as randomized complete block design (RCBD). The grain legume species cultivars for discussion were Bambara-groundnut (Vigna subterranea L. Verdc) (cv. Brianbeck MB 51), Groundnut (Arachis hypogaea L.) ( cv. JL 24), Cowpea (Vigna unguiculata) (cv. Pan 311), Blackgram (Vigna mungo) (Local market seed), and Mungbean (Vigna radiata) (cv. VC 1973A).Recent consideration of essential and other (non-essential and toxic) nutrient elements in crops, both macro- and micro-elements - can cause nutrient imbalances, reduction in growth and yield losses. Beneficial “elements”, they are not required by all plants but can promote plant growth and may be essential for several plant species. Recently, nutrient content is expressed as element content in dry matter (DM) percentages in DM for macro-elements, in DM for micro-elements (also known as ppm= pars pro million, 1 mg per 106 kg). Average concentration ranges of essential nutrient elements in crops, Oxygen (45), Carbon (45), Hydrogen (6), Sulphur (0.1 - 0.4), Chlorine (0.2 - 2.0), Na (Sodium) (0.01 - 10), Silicon (0.2 - 2.0), Manganese (0.1 - 0.4), Calcium (0.2 - 1.0), Potassium (0.2 - 6.0), Phosphorus (0.01 - 0.7), Nitrogen (0.1 - 6.0) and Concentration range percentages in DM Macro-elements Cobalt (0.02). Carbon (C) is ranked along N and P as mineral nutrients that are needed the most by plants for their growth and development. For C3 plants such as grain legumes, C is acquired through the process of photosynthesis and these C compounds play a significant role in the growth and development of C3 plants. However, the disproportionate alteration of the microbial C and N contents led to a distinct decrease of the C:N ratio for mung-bean residues at flowering but no change in the groundnut and Bambara-groundnut treatments. This suggests that the changes in microbial C:N ratio are mainly caused by the ‘recoverable’ residue inputs.Basically, the composition of the C isotopes is compared to that in the air to reveal water-use efficiency of the test plant species during its growth period. Calculated as δ13C, the water-use efficiency provides information on the ability of C3 plants to balance the process of acquiring carbon through the process of photosynthesis in relation to the water that get lost in the process. With regards to grain legumes such as cowpea, Bambara-groundnut, groundnut, mung-bean and black gram, quality residues include that which have a C/N ratio that is < 24 g g-1. There is a need to select crops particular that cultivated by smallholder farmers which can tolerate drought because South Africa has had high temperatures, and evapotranspiration coupled with reduced and scanty rainfall.The implications of future increases in atmospheric CO2 for the productivity of indeterminate C3 crops grown in rain-fed subsis-tence agricultural systems in the semi-arid tropics are stress resistance, therefore JL 24 cultivar in the study at Nelspruit, under field conditions manage to have shoot C content of 45% as best performer legume species planted. Plants also affect the residue turnover by excreting easily available organic C and N compounds which can interact directly with the microbial biomass and affect its size, ac-tivity, turnover rate or physiological status. However, following this concept, N will be set free from the microbial biomass as microbial residues, the relation between the parameters is difficult to prove because data concerning the residue quality are only available for the ‘recoverable’ residues and not for the rhizo-deposits.

19 The Techniques of Hydroponic System , Anbarasu Mariyappillai, Gurusamy Arumugam and V B Raghavendran
Hydroponics is soilless cultures where plants are created using a mineral enhancement for without soil. It redesigns genuine root limits, deftly water, agreeable oxygen and enhancements to the plant while giving physical, substance and natural assistance to the plant. When orchestrating a hydroponic nursery or home nursery, ought to pick a suitable space and techniques. Hydroponics systems are requested as open and shut methods. A hydroponic system implies the procedure for applying supplement answer for the plant roots. The hydroponics ended up being logically notable in a short period of time and this strategy lead to begin indoor and outdoor hydroponic planting rapidly.
20 A Dual Approach for Model Construction of Two-Dimensional Horizontal Flow   , Tinh Ton That, The Hung Nguyen and Dong Anh Nguyen
The two-dimensional horizontal flow model in the classical integration approach is integrated from the three-dimensional Na-vier-Stokes system of equations. Using the classical theory, the integral is taken directly from the bed to the free water surfaces. Consequently, the effects between the channel bed and free water surface, in the process of integration, was disappeared. However, with the proposed dual-process approach, the integral can be performed locally several times. The receiving equations thus allow to contain many physical phenomena which may be lost in the classical integral process. As a result, the derived model based on the proposed dual approach will be more complex and accurate than the classical one. In this paper, the authors perform twice integrals. The improved two-dimensional horizontal flow model was received from the dual approach which allows the calculation of flow pa-rameters, which, having the unusual phenomena in the channel as solid objects, liquids containing other added ingredients, external forces, reversals, and so on. Moreover, it provides flexible parameter adjustment based on the experimental data
21 The Arsenal of Morphological and Physiological Mechanisms Adopted by Barley (Hordeum vulgare. L) to Face Salt Stress Damage , Zied Hammami, Nawel Ahmed, Nejia Ben Hmida, Soumaya Tounsi, Sawsen Ayadi and Youssef Trifa
The success of programmes improving barley performance under abiotic stress must go through an understanding of mecha-nisms developed by the plant to counteract this stress. Our study fits into this framework. It aims to evaluate six barley genotypes from the MENA region, treated with two salinity levels: 1.2 and 14 dS/m. Three genotypes are salt-tolerant, and three are sensitive. They were grown under a controlled environment and in 40L PVC tubes using sand and perlite as substrate. The evaluation was based on 15 morpho-physiological parameters related to water, ion content, temperature, and chlorophyll fluorescence.The results confirm the existence of genetic variability for salt tolerance. Two Tunisian landraces ‘Suihli’ and ‘Ardhaoui’ and Oma-nis landraces ‘Batini 100/1B’ were not affected. Conversely, ‘ICARDA20’ and ‘Barley Mednine’ appeared to be sensitive to salt stress with a maximum reduction of 35% for improved genotype ‘Konous’. Results also show that salt tolerance in barley cannot be exclusively attributed to a single mechanism. All studied parameters significantly (p < 0.001) contributed to it. However, Stepwise regression revealed that plant water status expected by RWC is the key for salinity tolerance as well as a positive effect of K+ content, Fm/Fv, and leaf Temperature on proper water status. The results highlight the effeteness of one visual trait, the salinity damage index (DI), to estimate barley tolerance. Indeed, a strong correlation was observed between DI and the biomass reduction (P < 0.001, r2 = 0.96). In addition, correlation analyses showed that all parameters were inversely correlated with the DI.
22 Response of Carnation (Dianthus chinensis x barbatus) to Different Levels of Foliar Spraying of Amino Acid and Chemical Fertilizers , Yasser Ismail El-Nashar and Fatma El-Zahara Hussein El-Tony
The objective of this investigation was to measure the growth and flower response of carnation plants to the application of vari-ous levels (0, 2, 4 g.l-1) of amino acid (Terra-Sorb and Triamin) and chemical fertilization (Turo-fort and Nami), three times during the growing period, as a possible program for the production of quality plants through fertilization. Carnations (Dianthus chinensisx barbatus) were pot-grown in an unheated green-net greenhouse. The results showed that plants sprayed with fertilizer solutions showed a significant increase in the growth parameters. The results also showed that the treatments stimulated the flowering pa-rameters (number of inflorescences per plant, inflorescences diameter, flowering date, and inflorescences dry mass) and increased the number, diameter, and dry mass of inflorescences per plant, when compared to the untreated plants (control). The a, b, and total chlorophyll (a+b), carotenoid and anthocyanin content, gas exchange measurements and leaf mineral content (P, N, K, and Total car-bohydrates) were significantly increased compared to the control, as a result of the application of different levels of the chemical fo-liar fertilizer spraying solutions (Turo-fort and Nami). Carnations plants with foliar fertilizer solution application had higher leaf gas exchange (stomatal conductance (gs), transpiration rate (E), photosynthetic rate (PN) and plant intercellular CO2 concentration (Ci)).

Forty accessions with three check varieties of tossa jute (Corchorus olitorius L.) were characterized on the basis of morpho-ag-ronomic traits in genetic variability at Jute Agriculture Experiment Station, Manikganj during kharif season in 2016. The accessions were characterized for twenty-two morpho-agronomic attributes as per Corchorus descriptor in order to select superior genotypes for the genetic improvement of jute. Considerable ranges of variability were observed in stem colour, petiole colour, stipule colour, plant technical height, base diameter, dry fibre weight and dry stick weight. Considering the major yield contributing characters ac-cession no. 1039, 1115, 1124, 1234 and1245 performed better in most of the cases than the control varieties O-9897 O-3820 and BJRI Tossa Pat-4 (O-72).
26 Effect of the Use of Arbuscular Mycorrhiza for Plant Growth Promotion on Morpho-physiological Properties of Antirrhinum majus L. Under Salinity Stress , Fatma El-Zahara Hussein El-tony
The impact of arbuscular mycorrhizal (AM) fungi inoculation with mixed water irrigation on the vegetative and flowering growth, leaf mineral content, and chlorophyll (Chl) content of Antirrhinum majus L. (snapdragon) plants was studied through two seasons under two irrigation water sources. Five irrigation water treatments were applied as follows: T1 as a control (100% desalinized (DW)), T2 (75% DW + 25% well water, WW), T3 (50% DW + 50% WW), T4 (25% DW + 75% WW), and T5 (100% WW). The imposed salt stress conditions (T5) significantly reduced all vegetative and flowering growth, leaf mineral content (P, Na, K, Cl, and Ca), and chlorophyll content of the plants compared to those of the non-salted plants (T1). Inoculated snapdragon with AM fungi exhibited significantly higher values for most vegetative growth characters, flowering date, and spike length than those of non-mycorrhizal plants. With regard to interaction effects, the highest value of proline content of the leaves was detected with 100% WW (T5) and AM fungi treatments, which improved the salt stress tolerance compared to other treatments. Inoculated snapdragon plants with AM fungi showed both improved vegetative and flowering growth, mostly under salt stress conditions. With (T3) under mycorrhizal treatment, snapdragon plants showed the best results with earlier flowering dates, greater number of spikes, and longer spike length
27 Investigation of the Complex Influence of High- and Low-Molecular Glutenins and Crude Protein on the Quality of Bread Wheat (T. aestivum L.) , Sonya Doneva, Margarita Nankova and Stefan Krustev
The relation between high- (HMW) and low-molecular (LMW) glutenins with the quality indicators - sedimentation value, valorimetric value and bread loaf of a collection of Bulgarian wheat varieties was studied.A total of about 63% of the sedimentation value, 44% of the valorimetric value and 39% of the bread loaf was controlled by the two groups of glutenins and the crude protein. The high-and low-molecular weight glutenins had an almost equal share in controlling the sedimentation value and the valorimetric value. The LMW glutenins had a significantly higher share in controlling bread loaf than that of HMW glutenins. The participation of individual glutenin loci in quality control was not one-sided. It was mainly determined by genetic diversity and by the linking with the quality of the individual glutenin subunits.The relative contribution of crude protein to the control of quality indicators during the various harvest years was highly variable, but its optimum quantity was a necessary condition for showing the positive effect of glutenin subunits on the quality of the wheat varieties.
28 Food Supply Chain Disruptions and Resilience Under the Stress of COVID-19: Evidence from Nepal , Saugat Khanal, Padam Bahadur Poudel, Jeevan Lamichhane and Alagathurai Ajanthan
The food supply chain is a complex web with a number of stakeholders. Though the stocks of cereal at present are at satisfactory level, its stock in future is going to be depleted resulting from the disruptions in the food supply chain. Supply of agric-inputs has been severely affected. Developing countries and low income countries are most vulnerable to the impact of disruptions in the supply chain. Secondary sources of information are used for studying the food supply disruptions and resilience. Supply chain resilience has drained the curiosity of local to multinational companies and policymakers in remodeling the chain. As per the alarming projections to leave the long-term negative consequences, the importance of food availability has further risen. Consumer’s anticipation of future food crises has created panic and chaos in the food market; affecting the demand-supply chain. Transportation and public restrictions including transnational boundaries lockdown have created inconvenience to producers and distributors. With numerous noted obstacles from farm to firm, unemployment and poverty among low and middle class have been particularly hard hit. In this regard there is a need for behavioral change of the consumer, diversification of the supply chain and consumption of the local food.

The present investigation was carried out at Giza Agricultural Experiments and Research Station, Agricultural Research Center (ARC), Giza, Egypt during the two successive seasons 2018 and 2019 to evaluate three soybean genotypes (Giza 35, Crawford and DR10l) to infestation with lima bean pod borer using four bio and chemical insecticides (Diple-2x 6.4% DF, Biover10 % WP, Suncide Agri-pest and Lannate 25% WP) for increasing seed yield and net return. The treatments were four insecticides (Diple-2x 6.4% DF, Biover10 % WP, Suncide Agri-pest and Lannate 25% WP) beside water as control and three soybean genotypes (Giza 35, Crawford and DR10l). Split-plot distributions in a randomized complete block design with three replications were used. Insecticide sources were randomly assigned to main plots and soybean genotypes were allocated in subplots. The results showed that the bacterial insecticide Diple-2x 6.4% DF recorded lower pod infestation and seed damage than the other insecticides. Soybean genotype DR10l had lower pod infestation and seed damage, meanwhile the reverse was true for soybean genotype Crawford. Soybean variety Giza 35 recorded higher most yield traits than the soybean genotypes Crawford and DR10l. Soybean genotypes x insecticide sources interaction was significant for pod infestation, seed damage, seed yield per plant, 100-seed weight, seed yield per ha, and HI in both seasons. Spraying of the bacterial insecticide Diple-2x 6.4% DF in the flowering stage of soybean variety Giza 35 enhanced its tolerance to lima bean pod borer infestation with higher seed yield and net return than the other treatments.
32 Post Pandemic World Scenario and the Road to Food Sustainability , Himanshu Yadav
A century ago, when the world was fighting it’s Great war, which they didn’t know was going to be either the greatest or the first, a flu was spreading. Millions of lives were lost in that decade. Argu-ably, it was the decade which saw most deaths due to anthropo-genic and natural reasons combined. The virus killed 50 million people, while the war killed 38 million. On one frontier, masks were being used to protect self from Mustard gas and on the other, masks were used to prevent infection. The world, specially Europe was in a turmoil. The origin of the flu is still debated but it certainly did not originate in Spain.
33 Study of Physico-Chemical Status for Augmentation of Kamvari River Flow and Restoration of Water Quality in Bhiwandi City (MS)   , Snehal S Donde
Kamvari river was once a huge commercial navigation port, is now a diminishing perennial river of total 34 Km length flowing pol-luted through the Bhiwandi city, Kalyan Taluka, Maharashtra. Researcher being a Jalnayak recognized by Government of Maharashtra has taken initiative to revive and rejuvenate the river Kamvari along with other water bodies to restore its historic glory. The aim is to make all water bodies pollution free. Thus, origin to confluence of river course was located with Google Earth app and remote sensing images and documented for first time the origin in Depoli and Lamaj village and confluence in Thane creek, ultimately drain-ing in Arabian sea. The investigation of point and non-point sources of pollution, showed the establishment of most of the Textile Units, Slaughter houses and Tabelas in blue line area of river and direct release of untreated effluents from these sources along with untreated sewage water in the river. Water samples of river and other water bodies across Bhiwandi city was collected from multiple sites with intercept method, were subjected to Physico-chemical parameters tests. Almost status of all parameters in every sample was against the permissible limits and indicated percolation and mixing of creak water in ground water, among other factors. Re-spondents response during social assessment was very crucial to understand the rising pollution issues and risk to human health.Low capacity Sewage Treatment Plants (28%), no or non- functional Effluents Treatment Plants (ETP) in textile units, solid waste disposal in water bodies, power-looms without toilets need immediate action. An integrated approach working model has been rec-ommended to the administrative authorities in Bhiwandi region and District Collector office to work in tandem for revival of water bodies with appropriate restoration plans.

35 Fresh, Tiny, Crunchy, Green, Healthy… So Many Words Come to My Mind to Describe these Small Leafy Vegetables: Microgreens , Soniyo Yomichan
My lockdown days were boring like everyone’s. Since I travelled from UAE to Kerala, I was asked to stay in quarantine for 14 days initially, then later on more 14 days, a total of 28 days. I seriously didn’t want to waste those days. So, I thought gardening would be a better option and started planting my favorite table roses. The print media and broadcast media these days discuss how the whole economy is suffering from COVID-19. During these days the green leafy veggies, which are inevitable in our daily diet may not be easily available, as most of the markets are closed. I myself re-discovered those ingredients, which are far better than those veg-gies we buy from markets. Which can been grown in our kitchen, that neither require land nor fertilizers
36 Interplanting Soybean with Three Species of Orchard Trees Under Two Soybean Plant Distributions in Sandy Soils , Mohamed AF Selim, Yaser AA Hefny and Mostafa AM Ebrahim
A two-year study was carried out at El-Kassaseen Agricultural Research Station, Agricultural Research Center (ARC), Ismailia government, Egypt, during 2018 and 2019 summer seasons to evaluate the optimum interplanting system of soybean with orange, mandarin and mango for achieving high productivity of crops, land usage, and profitability under sandy soil conditions. Ten treat-ments were the combinations of three orchards trees (mango, orange and mandarin) and two soybean plant distributions with the same plant density (one row/ridge and two rows/ridge) in a strip plot design with three replications were taken. The rhizosphere of mandarin trees had higher soil CO2 and organic carbon (OC), meanwhile the reverse was true for mango trees under interplanting conditions. Wide soybean plant distribution increased fruit yield per ha by 10.23 and 10.06% for orange trees and by 7.49 and 6.29% for mandarin trees in the first and second seasons, respectively than the narrow one as a result of increased soil CO2 and OC, mean-while, all the studied traits of mango trees were not affected. On the other hand, interplanting soybean with mandarin trees recorded higher light intensity at the middle of soybean plant, the number of branches and pods per plant, as well as seed yields per plant and per ha than the other interplanting systems soybean + orange and soybean + mango in both seasons. Also, wide soybean plant dis-tribution gave higher all the studied soybean traits (except plant height) than the narrow one in both seasons. Moreover, soybean of wide plant distribution in soybean + mandarin system gave higher all the studied soybean traits (except plant height) compared with the other treatments in both seasons. Land equivalent ratio (LER) and land equivalent coefficient (LEC) values for intercrops were much greater than 1.00 and 0.25, respectively, indicating the advantage of the interplanting system than solid culture of the studied orchards. Growing four ridges of soybean variety Giza 22 (one row per ridge at distance 25 cm between hills) between mango trees cultivar Naomy is more profitable for Egyptian farmers followed by growing four ridges of the same soybean variety (two soybean rows per ridge at distance 50 cm between hills) with mandarin trees (Fremont cultivar).

A two year study was conducted at Sakha Agricultural Research Station, Kafr EL-Sheikh Governorate during 2017/2018 and 2018/2019 seasons. The objective of this study was to evaluate productivity of fifteen faba bean genotypes under natural infections with chocolate spot and rust diseases. Faba bean genotypes (Giza 40, Atona, Giza 3, Sakha 1, Misr 1, Santamora, Misr 3, Giza 843, Sakha 3, Sakha 4, Nubaria 1, L 1, L 2, L 3 and L 4) were randomly distributed in a randomized complete block design with three rep-licates. The results showed that faba bean genotypes Santamora, L2, Giza 843, Sakha 4, and Sakha 3 showed higher resistance to rust and chocolate spot diseases. This was positively reflected on seed yield in both seasons. However, the reverse was true for Giza 40 and Atona genotypes. A significant positive correlation was obtained between flowering or maturity date and each of rust and chocolate spot diseases. There is a highly negative correlation between days to 50% flowering or maturity date and each of number of pods per plant, seed weight per plant and seed yield per ha. There is a negative correlation between rust or chocolate spot disease and each of number of pods per plant, seed weight per plant and seed yield per ha. Conversely, there is a positive correlation between number of pods per plant and each of seed weight per plant and seed yield per ha. This study indicated that Santamora, L2, Giza 843, Sakha 4, and Sakha 3 genotypes could be grown to tolerate rust and chocolate spot diseases coincided with high productivity under Sakha region conditions.

The purpose of this research was to assess the effects of Gamma Radiation as well as Electron Beam on samples of Brazil nuts that are contaminated with Aspergillus flavus under temperatures of 30uC and a humidity of 93%. The process taked place in fifteen days of incubation where aflatoxins and mycobation are analyzed. The samples was further grouped into three groups namely, control, group 1 and group 2 which receive radiation of 0, 5 and 10 kGy dosage of electron beam (EB) and gamma radiation (GR). Some sam-ples of not inoculated were illuminated with a similar dosage to evaluate the sensors. The results indicated that 0.80 of the samples had an average water capacity. Illumination or irradiation of gamma radiation and electron beam at a dosage of 5 and 10 kGy were able to eliminate the A. flavus fungi in the samples of Brazil nuts. Analyzes of aflatoxin indicated that electron beam doses of 5 and 10 kGy lowers aflatoxins levels by 53.32 and 65.66%, respectively. Moreover, this same dosage of gamma radiation lowered the levels of toxins by 70.61 and 84.15%, respectively, as compared to the control group. Sensory assessment showed that texture and smell or the illuminated samples of Brazil nuts were acceptable
41 Assessment of Soil Microbes and Enzyme Activities in the Degraded Soils Adjacent to Industries and Mines and its Relation with Heavy Metal Contaminants , K Laxminarayana, Sulekha Pradhan, M Madhumita Das and M Nedunchezhiyan
A study was undertaken to assess the microbial diversity and enzyme activities and their relationship with soil properties in the soils adjacent to chromium, iron and coal mining areas of Jajpur, Keonjhar and Jharsuguda districts and adjacent to industrial areas as well as ash ponds of thermal power plant and aluminium refinery of Angul, Koraput, Rayagada, Jagatsinghpur, Sundargarh, Bhadrak, Balasore, Mayurbhanj, Cuttack, and Ganjam districts of Odisha, India. The effluents from the mines are discharged to nearby arable lands and water bodies causing acid mine drainage. The soils of the study area are strongly acidic to slightly alkaline in reaction (pH 4.23 - 7.85), non saline, and having very low to high organic carbon (0.15 - 1.88%), low to medium in available ni-trogen (N), low to high in available phosphorus (P) and potassium (K). The soils contain toxic levels of iron (Fe), manganese (Mn), chromium (Cr), nickel (Ni), lead (Pb) and relatively higher status of available zinc (Zn). Highest available Fe (240.8 mg kg-1) was observed in the soils adjacent to sugar factory of Ganjam district, Mn in the soils of coal mining areas of Jharsuguda (146.0 mg kg-1), highest Cr (178.4 mg kg-1) and Ni (12.4 mg kg-1) in the soils of chromium mining areas of Jajpur and highest Pb (18.9 mg kg-1) in the bauxite mining areas of Koraput district of Odisha. However, highest available Cu (9.02 mg kg-1) and Zn (6.36 mg kg-1) contents were recorded adjacent to Rourkela steel plant areas of Sundargarh district. Toxicity of heavy metals in the soils of Jagatsinghpur district led to very low biological activities in terms of dehydrogenase (0.186 μg TPF hr-1g-1), fluorescein diacetate (0.152 μg g-1 hr-1) and alkaline phosphatase (9.68 μg PNP g-1 hr-1). The study emphasized that toxic levels of heavy metals in these mining and industrial areas and consequently their uptake in to the plant system is very much harmful to the livestock and human beings and there is an urgent need to advocate the people in these areas to adopt proper remedial measures so as to minimize the levels of these elements in the soil-plant-animal-human chain.

45 Potential Use of Angiosperm353 to Help Bio-prospectors Differentiate between Members of the Genus Attalea , Jonathan Daniel Hulse
The family of palm trees, Arecaceae, provides to the incredible biological diversity in the tropics, and currently includes 181 gen-era and over 2600 species. Of these 2600 plus species, only a portion of these species have been molecular characterized because many of these species had little or no economic value to Americans and Europeans, so they have simply not been a priority to bio-prospectors, until now. The advancement of Angiosperm353® a biotechnology kit, can differentiate the inner workings of this vast plant family, and minute details can finally be resolved. In particular, there have been discrepancies between the species of the genera Attalea, which include agriculturally and economically important members, that share similar morphology, which are hard to differ-entiate morphologically. Every member of this genus have not been molecularly characterized at this point in time, and this manu-script proposes the use of Angiosperm353® to help resolve the inner workings of this enormous plant family, to help bio-prospectors correctly identify members of this genus.

47 Assessment of Postharvest Supply Chain Loss of Banana and Tomato in Asella Town , Yonas Tega Gebeyehu, Tesfaye Mekuriyaw and Yidersail Hune
Postharvest loss is quantitative and qualitative food loss in the postharvest system which is a serious problem in Ethiopia. Fruit ripening is a complex process that dramatically changes in colour, texture, flavour, and chemical compositions. Tomato fruit ripening happens after harvest this ripening processes and storage temperature can severely affect the final product. Banana is a climacteric fruit with poor storage characteristics as it presents a high respiration rate after harvest and ethylene production, which make it highly perishable and prone to postharvest losses. This study was conducted in Arsi zone, Asella town. The objective of this research was to assess the postharvest supply chain loss of banana and tomato, Study the extent of loss in the supply chain (from wholesaler to consumer), put suggestive solutions to reduce such postharvest loss of banana and tomato. Asella town was selected purposely to study due it is known as major marketing activity in the region. In this study, the survey was conducted with about 102 respondents to assess for such fruit losses. The result revealed with 18.2% and 11.82% loss of banana and tomato postharvest supply chain re-spectively. Transportation, loading and unloading and storage condition were the main factors in postharvest supply chain loss of banana and tomato and storage condition is identified as the key issue for product loss.

49 Selenium Content in Soil and Wheat Grain in Bulgaria , Stefan Krustev, Violina Angelova, Penka Zaprjanova, Margarita Nankova and Krasimir Ivanov.
Selenium (Se) is an essential but highly toxic element. Its organic compounds play an important role in biochemistry and nutrition of the cells. Shortage or surplus of this element leads to the occurrence of socially significant diseases. Se concentrations in different regions of the world and its levels in different foods vary widely. Bulgaria does not appear in the World Atlas of Se, and the scarcity of data about the neighboring countries shows serious lack of Se, causing concern about human health in the region. As a result of the present study, data on the status of selenium in soils and wheat from 60 points from the main grain-producing regions of Bulgaria. The results show that there is a significant deficiency of selenium in the soil and especially in the grain of wheat, which is a major source of selenium and its entry into the human body for our geographical areas through the bread.
50 Experimental Measurement of Creep Deformations of an Unsaturated Silty Soil with Matric Suction , Tomoyoshi Nishimura and Masafumi Matsumoto
Geotechnical engineers often encourage geological disaster in ground related to saturated soil and unsaturated soil. Landslide, settlement and slope failure related to creep phenomena are typical problems in geotechnical practices. Creep behavior of saturated soils can explain including time-dependent on effective stress of saturated soil by Terzaghi effective stress theory. Some papers al-ready published to apply the practice problems related soft ground settlements. Landslide in unsaturated conditions was induced by changing of matric suction as one stress of unsaturated soil stress variables, and some experimental researchers have reported inter-esting test results and effectively models for unsaturated soil creeping deformations. This study conducted out unsaturated soil creep test, which suction controlling has a low range with two lateral confining pressures using revised unsaturated triaxial compression apparatus. Solving the practical problems regard to unsaturated soils consider the properties of unsaturated soil that are subjected to creep before occurrence instability of natural slope. Excess pore-water pressures were measured and evaluated matric suction in unsaturated creep test using pressure membrane technique that creep stress increased step by step till unsaturated soil was failure. Comparison failure condition obtained from conventional triaxial compression test under undrained condition and mean effective principal stresses against creep stress. It was found out mean effective principal stress reached to failure line. In addition, soil-water characteristic curve was investigated in order to interpret hydro-mechanical properties and relationship between unconfined com-pressive strength and matric suction was obviously useful that shear resistance of unsaturated soil depend on matric suction.

Fruit fly is one of the serious pest of Citrus. Among 16 species of fruit fly reported in Nepal, 6 species of fruit flies were found in citrus fruits. According to pest surveys done in Dhankuta and Sindhuli, the species found are: Melon fly (Bactrocera cucurbitae), Ori-ental fruit fly (B. dorsalis), Peach fruit fly (B. zonata), B. tau, B. scutellaris and Dacus longicornis. Chinese fruit fly, B. minax (Enderlein) (Diptera: Tephritidae) has created devastation in the sweet orange orchards in eastern hills of Nepal and the infestation rate have been found up to 100%. Unlike other Bactrocera species, B. minax is univoltine and oligophagous and adult flies becomes active from April to July. The two highly attractive para-pheromones, Cue lure and Methyl Eugenol used for many Bactrocera species are not at-tractive for this species. For B. minax, food based lure i.e. protein baits are used. Maintaining field sanitation by proper disposal of infested fruits, winter/summer ploughing, visual cue lures such as colored sticky spheres, mass trapping by using para-pheromones and food based lures, foliar insecticidal spray are the pest management strategies adopted in China, Bhutan, Sikkim and Nepal. Area Wide control program has been launched using technologies: monitoring, Great Fruit Fly Bait (Protein Hydrolysate 25%+0.1% Ab-amectin) developed by Ecoman Biotech, China, trapping and field sanitation in the year 2018 which has proved successful in control of B. minax in the sweet orange orchards of Sindhuli.
52 Empowerment of SC/ST Communities Through Watershed Activities in Rayalaseema Region , PVRM Reddy, B Janardha Reddy and BV Ramana Kumar
Semi-arid regions like Rayalaseema of Andhra Pradesh were adopted by programmes like Integrated Watershed Management Program in order to improve productivity and livelihoods especially marginalized sections such as SC/STs. These are poor, asset less, socially depressed, and economically backward. With this aim, IWMP provided financial assistance to improve their lives by engaging them through farm-based and non-farm based activities under the components of Natural Resources Management, Productivity Sup-port Improvements and Livelihoods for the period 2017-2020. To evaluate their performance and improvement, the study carried out a detailed field-based study with extensive field surveys; in-depth interviews focused group discussions, case studies and also collected secondary data for effective analysis. The results can be seen in the target-based activities of financial assistance and works provided to develop their land and livelihoods. This further led them to move towards sustainable development in all spheres of life especially, their self-esteem and social imagery.
53 Comparison Between Value of Indian Major Carps and Air Breathing Carps in Open Inland Fishery Sector , Swapna Ghosh and Pratik Majumdar
In India, 75% population are live in rural area and agriculture fish farming are major occupation of them who are live in village. The total fish production of 10.07 million metric tonnes in India presently has nearly 65% contribution from the inland sector and nearly the same from culture fisheries. Actually Fish constitutes a major source of protein in our diet. Fish apart from being important in human diet, its fatty acid are currently under intense scientific investigation because of numerous health benefits attributed by them. The amount of protein in fish muscle is usually somewhere between 15-20%, but values lower as 15% or as high as 28% are occasionally met with in some species. IMC are demandable and easily acceptable for consumers, it can fulfil population demand for their nutritional value in everyday life and air breathing fish are not easily available and acceptable by all classes of consumer. Among IMC Rohu (Labeo rohita) achieve the 1st position as it can fulfil population demand for their nutritional value at a lower cost for the above reasons. Even induced breeding become more popular in IMC where as the anthropogenic activity is tough for air breathing fishes. Their seeds collected from the natural environment, but due to exposure of chemicals in land and water the population be-come enough less day to day. So we have to save them from the list of endangered species for their nutritious value as compare to protein and lipid.
54 Phytoremediation Potential of Castor Bean ( Ricinus Communis L.) , Violina Angelova and Mariana Perifanova Nemska
The goal of this research was to investigate the potential use of Ricinus communis L. (castor oil plant) for the remediation of metal-polluted sites. This field study was performed in industrially polluted soils that contain high concentrations of Zn, Pb and Cd situated at different distances (0.1, 2.0 and 15.0 km) from the source of pollution – KCM (Non-Ferrous Metal Works) near Plovdiv, Bulgaria. The amount of heavy metals in different part of castor oil plant (roots, stems, leaves, capsule, seeds) and oils was determined by ICP. The castor oil plant is tolerant to heavy metals. Bioaccumulation factor and translocation factor values were greater than one, which suggests that heavy metals accumulate efficiently in the shoots. The presence of low levels of saturated and polyunsaturated fatty acids as well as high levels of monounsaturated acids result in the production of a high quality biodiesel. The castor bean is a plant that can be used simultaneously for phytoextraction of heavy metals from soils and as biofuel. It can be grown on soils heavily con-taminated with heavy metals, which are not suitable for the cultivation of food crops.
55 An Application of Markov Chain Model to Study on Trade Direction of Export of FCV Tobacco from India   , Yogesh HC and SK Srivastava
Tobacco is one of the important commercial crops of India and also called as “golden leaf ”. It provides employment directly and indirectly to 38 millions of people. Indian tobacco is exported to over 119 countries across the globe. During 2015-16, India’s un-manufactured tobacco (FCV and non-FCV) exports accounted for about 86 per cent of total exports of tobacco and tobacco products in terms of quantity and 71 per cent in terms of value in rupees. Out of the total Indian unmanufactured tobacco exports, FCV tobacco exports constituted 72 per cent in terms of quantity and 81% in terms of value. FCV tobacco exports were in the order of 1,51,670 Metric tons valued ₹ 3,495.81 crores ($ 531.48 million) against 1,49,700 Metric tons valued at ₹ 3,201.71 crores ($ 486.73 mil-lion) during the same period last year showing an increase of 1 per cent and 9 per cent in terms of quantity and value, respectively. Therefore, the present study has been conducted with reference to FCV tobacco; to examine the pattern of export destination of FCV (Flue-cured virginia) tobacco. To achieve this, annual export data on region-wise for the period 2010-11 to 2015-16 has been used and analysed by using the first order Markov chain approach. The study reveals that West Europe followed by Africa and North and South America are the best and loyal importer of unmanufactured tobacco from India. Also, it is suggested that India should not only depend on these trade partners only but also diversify its exports to other regions too.

The stabilization of river system is crucial in socio-economic development, especially in agricultural development, for example irrigation water withdrawal, flood drainage to reduce the impacts of flooding on crop production, etc.
57 Stability and Scrutiny Using (Ammi): Model of Bread Wheat Over the Years in Cold Arid Harsh Conditions of Kargil and Zanaskar (Ladakh)- India , Mushtaq Ahmad1, Faizan Ahmad1, Ejaz Ahmad Dar, Rizwan Rashid, Shahnowaz Ahmad, MH Khan, Rohie Hassan and NR Sofi
Field experiments were carried out using 20 genotypes for 3 consecutive years (2017-2019) under two randomly completed conditions (Zanaskar Kargil or irrigation rainfall) to identify high-grain infarct-able wheat genotypes obtained by a single parameter. RBD with three copies in each environment. Combination testing of variation showed significant differences for the GE (genotype-environment) cardinal. The results of AMMI (additive main effect and multiplicative interaction) show that the first two AMMI (AMMI 1 - AMMI 2) are symbolic (P < 0.01). It became clear that the division of whole squares was a major source of environmental impact variability, followed by interplay and genetic type effect. The GE cardinal genotype is three times greater than the effect, indicating the presence of different environmental groups. The AMMI Invisibility Value (ASV) lost the G12, G18, G13, G14 and G11 genotypes, respectively. Differentiation to SE is not a physical selection criterion because most incomplete genotypes do not provide the best yield performance and, therefore, grain yield and ASV can be considered simultaneously in a single parameter-free index. Depending on the rainfall and irrigation conditions, the G1 and G18 genes and the High Grain Genome Type Selection Index (GSI) were matched to the results of the biplot observation.
58 The Role of Indigenous Knowledge and Livelihood to Adapt to Floods in Sustainable Development in Mekong Delta, Vietnam (A Case Study in An Giang Province) , Pham Xuan Phu and Ngo Thuy Bao Tran
This research was carried out to explore the role of the appropriateness of farmer’s indigenous knowledge and their adaptive capacity to floods in An Giang province. KAP (Knowledge-Attitude-Practice), PRA (KIP and focus group discussion) and household survey have been applied to collect data. The results showed that indigenous knowledge plays an important role in adapting to changes in the environment. The Livelihood Vulnerability Index (LVI) in different Zone (upper zone, middle zone, and lower zone) was decreasingly based on major components as social networks, knowledge and skills, natural resources, finance and incomes, livelihood strategies, natural disaster and climate variability. The research also suggested some solutions to conserve the valuable indigenous knowledge in adapting the change of climate of local people.
59 Effect of Larval Parasitoid, Cotesia flavipes on Chilo partellus Under Laboratory Conditions , Zulnorain Sajid, Muhammad Ammar Latif, Muhammad Abdul Basit, Muhammad Usman, Wasim Javaid, Bilal Jafar, Hafiza Sehrish Bashir and Rashid Ameen
Maize is third most important crop of Pakistan that attacked by many insect pests, among all these Chilo partellusis a notorious pest of crop. Chilo partellus is caused huge economic losses of crops in Pakistan. An experimental study was conducted in insect Bio Control Lab at the Department of Entomology, PMAS UAAR during 2018 to check the effect of Cotesia flavipes on Chilo partellus under control conditions. Adult duration of Cotesia sp. was 41.46 hours. Rate of parasitism was 76 percent in 4th instar larvae of C. partellus. Mean number of pupae per larvae were 41-46 pupae per larvae. The mean pupal duration of Cotesia sp. was 8 days. Rate of parasitism was 73 percent in 3rd instar larvae of C. partellus. From each parasitized larvae the mean adult emergence was 28 adults per larvae. The mean pupal duration of Cotesia sp. was 9 days.
60 Breeding Approaches for Climate Resilience in Maize (Zea mays L.): An Overview , Anurag Tripathi, Rahul Kumar, Suresh Yadav, Jeet ram Choudhary, Mukesh Choudhary and H C Lohithaswa
Climate change impacts agriculture in numerous ways including rising average temperatures, rainfall, changes in pests and dis-eases, rise in atmospheric carbon dioxide, ozone concentrations at ground level and changes in the nutritional quality of certain foods. Therefore, achieving global food security for rising global population under limited arable land is a major challenge in the twenty-first century. Maize plays an ever more vital role in the growth of global grains. Maize being a C4 plant has a high yield po-tential as witnessed from highest compound annual growth rate over last decade. However, in many countries maize production has been plateaued due to full exploitation of hybrid and manufacturing technologies. Therefore, maize ideotypes with favourable traits architecture need to be developed for increased stress resistance and higher yield under changing climate. In maize abiotic stress such as drought leads to delay in silking that result in an increase in the anthesis-silking interval, which is a major cause of yield losses. Acidic soils also conflict with maize production (Zea mays L.) resulting in yield losses of up to 69%. In this review, we have discussed the current challenges and different breeding approaches for sustainable maize production under changing climate i.e. climate resilience. With the advent of recent advances in omics approaches including genomics, transcriptomics, proteomics and metabolomics, great opportunity exists for development of elite climate resilient maize cultivars

62 Economic Growth and Expansion of the Agricultural Frontier, Case Study: Ecuador (1985 - 2015) , Rafael Reyes, Wilman-Santiago Ochoa-Moreno, Luis Rojas Ojeda, Elisa Toledo and Viviana Torres
In this research, the relationship between the agricultural frontier and production for Ecuador in the period 1985 - 2015 is ana-lyzed. It begins with a review of the existing literature, then, econometric models of autoregressive vectors and error correction are used. The results show that as production rises, an increase in the agricultural frontier is generated; results that are consistent when additional covariates are added. Among the main results, it is observed that the autoregressive vector model demonstrates that the variables (production and agricultural frontier) have a long-term equilibrium relationship. Also, the error correction model indicates that as the gross domestic product increases, the agricultural frontier expands. In conclusion, the results are coherent with each oth-er and reinforce the idea that the Ecuadorian economy in the period of the analysis is still tied to dependence on livestock products.
63 Linseed (Linnum usitatissimum L.) - An Oilseed Crop with Potential to be Used in Many Ways: Review Article , Anand Paul Bunga and Pragnya Reddy Patlolla
Linseed is an important, yet underutilised oilseed crop of the world. It can be used as food and feed, as raw material for pharma-ceuticals, industrial use, textile industries etc. It is an excellent source of omega 3 fatty acid and can be used as a substitute for non-fish eaters. The fatty acid composition is comparable to that of soybean. Apart from oil, it also contains good amount of proteins and secondary metabolites. The nutritional value of the linseed can be further improved by research in various fields like plant breeding, agronomy, food science etc. More knowledge is needed on how the quality of the oil is affected by various biotic and abiotic factors. New ways should be brought up to include linseed in our daily diet.
64 Is Plant Nitrogen Depletion Really Linked to the Biosynthesis of Carbon-Rich Defense-Related Compounds in Organic Products? , Simona Fabroni and Paolo Rapisarda
Previous studies speculated on the existence of an inverse re-lationship between the available nitrogen and the accumulation of defense-related secondary metabolites in plants [1], as a con-sequence of C:N ratio unbalance. According to this hypothesis, the lower nitrogen contents of organically grown plants lead to a shift from the N-containing compounds to the production of carbon-rich defense-related phenylpropanoids. It has been also suggested that this behavior is putatively linked to the increased resilience to pest attacks and damage exerted by organic plants [2-4]. Re-cent research [5] showed that long-term organic fields have been associated with no consistent difference in nitrogen and carbon content, nor in C:N ratio, between the organic and conventional produces. In parallel, pest attacks were preferentially settled on conventional plants respect to organic ones. Organic management reduced insect population but no evidence about plant nutrient unbalance was directly linked with. The study demonstrated that organic soil management promoted salicylic acid build-up, which resulted in discouraging plant–insect interactions. Indeed, salicylic acid accumulation was not associated with lower nitrogen content of organic plants but it depended on alterations in soil microbial communities associated with long-term organic management. The study showed that over-presence of specific microbial groups in-duced plant resistance to pest attacks. By this way, it can be pos-tulated that organic practices promotes plant resistance through derived changes in soil microflora.

66 Effect of Wheat Plant Distribution, Nitrogen and Potassium Fertilizer Levels on Wheat-sugar Beet Association , Ahmed M Sheha, Amr S Shams and Mohamed M Lamlom
A two-season field experiment was conducted at Gemmeiza Research Station, Egypt, during 2017/2018 and 2018/2019 to study the effect of some wheat plant distribution systems (2, 3 and 4 rows), three N fertilizer levels (80, 100, 120 kg N fed-1) and three K fer-tilizer levels (24, 48, 72 kg K fed-1) on the productivity of both crops and farmers benefit. Sugar beet was planted on both sides of the bed (120 cm width), wheat was planted in all intercropping treatments at 25% of sole culture seed rate. A split-split plot design with three replications was used. Wheat plant distribution allocated to the main plots, N fertilizer arranged in the sub-plots and K fertilizer is presented in the sub-sub plots. Wheat plant height and spike length recorded the highest values by wheat planting in 2 rows fol-lowed by in 3 and 4 rows was showed the lost values in both seasons. Simultaneously; the other characters of wheat i.e. spike grains wt., 1000-grain wt., no. of grains spike-1, no. of spikes m-2, grain yield fed-1 and straw yield ton fed-1 recorded the highest values with 4 wheat rows in both seasons. All studied characters of wheat were increased by increasing N fertilizer levels from 80 to 100 up to 120 kg N fed-1 in both seasons. Most wheat characters were decreased by increasing K fertilizer levels from 24 to 48 up to 72 kg K fed-1in both seasons. Most of the wheat characters were significantly influenced by the different interaction under study in both seasons. Sugar beet yield and its components as well as sugar% recorded the highest values when wheat was planted in 2 rows. Increasing N fertilizer levels increased all studied characters in both seasons. All sugar beet characters were recorded the highest values by using 48 kg K fed-1 followed by 72 and 24 kg K fed-1 in both seasons. Most sugar beet characters were significantly affected by the different interactions between factors under study in both seasons. The best land equivalent ratio (LER) and Land Equivalent Coefficient (LEC) achieved the highest values with treatment included 2 wheat rows with 120 kg N and 24 or 48 kg K fed-1. Simultaneously, Aggressivity (A), wheat was the dominant crop and sugar beet was dominated in both seasons. The treatment of wheat planting in 4 rows with 120 kg N fed-1 and 24 kg K fed-1 recorded the highest values for both total income and net return in both seasons
67 Forest Genetics and Tree Breeding , Kannan CS Warrier
More than 10 million different species of animals, plants, fungi and other micro-organisms inhabit the Earth. They and the habi-tats in which they live represent the world's biological diversity. It has been recorded that humans use about 40,000 species of plants and animals for food, shelter, clothing and medicinal needs. For-ests are the most diverse ecosystems on land, because they hold the vast majority of the world's terrestrial species. Priceless bio-diversity is threatened by deforestation, forest fragmentation and degradation, hunting and the arrival of invasive species from other habitats. We are losing the invaluable treasure at an alarming rate that, it has been estimated that, within the next 10 years, one out of every four known species may have been wiped off the planet. It has also been estimated that to meet the innumerable demands that humans make on nature each year, we may require about more than an additional half of Earth. That is about 1.6 earths to satisfy our greeds!

The management of weeds by chemical herbicides creating adverse effect on human and animal health so there is urgent need for alternative weed control option to save environment by an environmental friendly and sustainable options. Bioactive compound of fungi is great source for the development of new herbicide and its offer an ecofriendly alternative to control weeds. Here We have evaluated mycoherbicidal activity of cell free culture broth (CFCF) of selected strains against Cassia obtusifolia. Phytotoxic contents of natural metabolites present in CFCF of Curvularia lunata (FGCCW#33), Phoma herbarum (FGCCW#07), Myrothecium roridum(FGCCW#03) and Fusarium roseum (FGCCW#61) against Cassia obtusifolia were evaluated by seedling bioassays. In preliminary bioassay, the CFCF of FGCCW#03 of 28 days old were shown maximum phytotoxic effect on seedling of Cassia obtusifolia at 100% concentration. The symptoms were observed as browning and necrosis of weeds. With effective formulation and cheap mass produc-tion of this mycoherbicidal strains can possibly use as mycoherbicide for control of Cassia obtusifolia in future.
69 Alternaria Blight of Tomato: A Review of Disease and Pathogen Management Approaches , Surbhi Garg, Data Ram Kumar, Suresh Yadav, Mohit Kumar and Jagdish Yadav.
Taxonomically, genus Alternaria comes under Deuteromycetes phylum which includes different saprophytic and endophytic spe-cies. It is famous due to its notoriously destructive pathogens. It majorly affects various plant families e.g. Cucurbitaceae, Cruci-feraceae and Solanaceae which are agriculturally important crops possess high nutritional and economical values. The crops suffer from various bacterial, viral, fungal and nematode diseases. Among the above mentioned diseases, early leaf spot disease caused by pathogen Alternaria solani is one of the most devastating diseases resulting in loss upto 78%. Most of the species of Alternaria lacking in teleomorphic stage whereas few species have teleomorphs in their disease cycle. Alternaria being necrotrophic it leads to severe damage to plant and its produce. Besides the involvement of toxins in pathogenesis or invasion, few genes or gene products also have major effect on pathogenicity. In the present review, we described in detail about efficiency of plant and herbal extract, bio control agents, cow by products and fungicides against A. solani, that not only effective in managing the disease but also economic and ecofriendly.
70 Diallel Studies and Heritability Estimates Using Hayman's Approach in Ocimum spp.   , Smita Singh
Diallel analysis of Hayman was performed removing reciprocal in basil, the experimental material consisted of morphological diverse genotypes and their 21 direct crosses i.e. F1 populations. The traits days-to-flowering (50%), plant height (cm), no of branch-es/plant, inflorescence length (cm), fresh herb yield (g)/plant, oil content (%), oil yield (g)/plant, days-to-maturity, methyl-chavicol content (%), linalool content (%), citral content (%), eugenol content (%) explored additive type of gene effects. t2 for all the charac-ters are non-significance so its indicate validity of the hypothesis postulated by Hayman. Regression line for days-to-flowering (50%), days-to-maturity were below the origin showing the presence of over-dominance while for branches/plant, ocimene content, linalool content, camphor content and methyl-chavicol it was above the origin suggesting the presence of partial-dominance. Regression line for plant height, inflorescence length, fresh herb yield, oil content and oil yield were through the origin indicating the presence of complete-dominance. Narrow sense heritability estimates 2∧h(ns)% ranged from 7.9% (lowest) for inflorescence length to 59% (highest) for oil content. Genetic advance over mean ranged from 0.54 (days-to-maturity) to 53.11 (branches/plant)
71 Dwarfing Responses of Leonotis leonurus (L.) R.Br. Lamiaceae Using Foliar Growth Regulator Applications to Induce Compactness in Flowering Potted Plants , Khanyisa Boyce, Charles P Laubscher and Mack A Moyo
The insatiable demand for novel floral forms in the ornamental horticulture industry continues to drive the search for such plant species, particularly in biodiversity-rich regions such as South Africa. The aim of the present study was to evaluate the effectiveness of Cycocel®, a plant growth retardant, in manipulating growth and compactness in Leonotisleonurus, a plant with potential high or-namental value in the potted flower industry. Application of Cycocel®, especially at a concentration of 4 mg/L significantly reduced both height and plant width of L. leonurus plants growing in a soilless hydro culture system. In addition, application of the growth retardant had a significant influence on increasing the shoot proliferation in L. leonurus plants. The number of new shoots produced in week 6 of the 8-week growing period was about threefold higher compared to the control. The reduction in height and width observed in the present study may be due to the interference with key enzymes involved in the gibberellin biosynthesis pathway. Overall, application of Cycocel® had the desired effect in controlling growth parameters in L. leonurus plants, thereby improving com-pactness and enhancing its commercial value in the flowering potted plant market.
72 Assessment of Essential Metals in Selected Fish Feeds and Cultivated Fish Species in Bangladesh and their Impacts on Human Body , Biraj Saha, Md Abdul Mottalib and ANM Al-razee
Cultivated fishes are major protein and microelement sources for all sorts of people in Bangladesh due to its availability and af-fordability. Essential metals are persistent in the environment and are subject to bioaccumulation in the food chain. Fish is at the top of the aquatic food chain and normal metabolism of fish may accumulate large amounts of different essential metals from water, food or sediment. This study was carried out to determine essential metal concentrations in the flesh of some cultivated fish species and commercial fish feeds available in Bangladesh. The essential metal concentration in fish and consumed fish feed were assessed by Inductive Coupled Plasma Optical Emission Spectroscopy (ICP-OES) with significant variation (P < 0.05). The concentration (mg/kg - dry weight) of Fe, Cu, Zn, Na, K, and Ca were observed 23.33 - 63.3, 12.80 - 20.62, 10.00 - 26.25, 214.2 - 367.68, 285.71 - 485.71, 256.89 - 432.65 in selected commercial fish feeds whereas those were found 33.33 - 80.83, 14.00 - 31.80, 20.60 - 49.25, 250.98 - 500.78, 400.76 - 587.32, 408.16 - 857.14 in cultivated fish species. All analyzed metal concentrations were within the acceptable of World Health Organization (WHO, 2004), Food and Agricultural organization (FAO, 2004), European Union (EU, 2010) and US Envi-ronmental Protection Agency (USEPA, 2011) and Total Hazardous Quotient (THQs) value of all the selected metals were lower than 1, which suggesting no remarkable non - carcinogenic health hazards for adult population
73 Agriculture during Pandemic , Lirola Keri
The year 2020 since its inception has started with a situation different from normal. The outbreak of the epidemic in several countries simultaneously led to the creation of the pandemic de-clared worldwide by the WHO itself. This change came unexpect-edly. At the center of world attention was health. The social and economic life of mankind around the world changed suddenly. The prolongation of the pandemic created the belief that isolation was no longer a solution but a choice of the moment. For all sectors to be revitalized and continue their activity they had to adapt to new conditions of physical distancing. But some activities much needed for basic needs could not be accomplished in this form. One of them is also agricultural and livestock activity. The supply of consumers with agricultural and livestock products and products had to continue normally, especially in this period when the de-mand would be higher due to two factors; first, people had enough time to consume food at home, and; second, the closure of restau-rants, bars and hotels. An additional supply had to respond to the increase in demand. But if the pandemic increased demand, the same cannot be said for supply. Not only is the supply of such prod-ucts, as of any other product, limited in the short term, but also because exchanges of goods and products between countries were temporarily suspended. For net exporting countries supply could not have a significant difference from demand. For net importing countries traders had to find other resources to meet demand. Such places where demand remained undiscovered turned their eyes away from domestic production. This situation was presented as a golden opportunity for local producers who had to guarantee the sale of their agricultural and livestock products.

Measuring plant-associated nitrogen fixation in agricultural systems has a potential precision of the δ15N natural abundance method in field estimates of nitrogen fixation by crop and pasture legumes in South Africa thus provided influence of mycorrhizal associations on foliar δ15N values of legume and non-legume shrubs and trees in the fynbos of South Africa, Western Cape province with implications for esti-mating N2 fixation using the 15N natural abundance method
76 Characterization and Distribution of Potyvirus Species Infecting Sweet Potato (Ipomoea batatas) in Burkina Faso , Fidèle Tiendrébéogo, Ezechiel B Tibiri, Koussao Somé, James Bouma Neya and Nicolas Barro
Virus species belonging to the genus Potyvirus are the most common viruses infecting sweet potato crop. Among these viruses, Sweet potato Feathery Mottle Virus (SPFMV) is the most damaging and widespread in the world. To assess the potyvirus disease on sweet potato in Burkina Faso, a total of 300 samples were collected from the nine largest sweet potato producing regions. Samples were analyzed using RT-PCR and products were Sequenced. Bioinformatic analyzes were performed to know the strains of the virus-es. The results revealed that SPFMV is the main Potyvirus infecting sweet potato in Burkina Faso with a prevalence of about 28.33%. A total of seven isolates of SPFMV were successfully sequenced and used for phylogenetic analyzes. These isolates have shown 99% nucleotide identity with the phylogroup A-II (SPFMV-O), and some of them had 95% nucleotide identity with phylogroup B (SPFMV-RC). This study showed that SPFMV is the main Potyvirus-infecting sweet potato in Burkina Faso
