The histochemical investigation of Jeewanu showed the presence of RNA-like material. The Abiogenesis of RNA-like substances in Jeewanu mixture supports RNA world theory suggesting its primitively.
2 Phytoremediation potential of Brassica juncea L. with reference to Atrazine, Khan Shahana J and Gaikwad Rupali S*
Atrazine is one of the most widely used herbicide in the agriculture today. It is a triazine herbicide that is used for control of broad leaf weeds, mainly in corn and sorghum and also many other crops. Atrazine is highly persistent in soil and is leached directly from the soil into groundwater, surface water, and drinking water. Contamination may pose a significant threat to humans, wildlife, and the environment. Greenhouse experiments were carried out to determine potential capability of Brassica juncea L. plant to remediate atrazine contaminated soil. Persistence of atrazine in the treated soil and its residue were estimated by High performance liquid chromatography (HPLC). Data obtained with soil treated at 1000ppm of atrazine showed that residues of atrazine were less in soil planted with Brassica juncea L. compared with unplanted soil. Considerable concentration of atrazine i.e. 20.5?g/ml and 18.5?g/ml were detected in sterilized unplanted soil and soil planted with Brassica juncea L. respectively after 30 days of sowing. While these values were 17.5?g/ml and 14.0?g/ml in non-sterilized unplanted and planted soil respectively. This study demonstrated that residues of atrazine were reduced at faster rate in treated soil which was planted with Brassica juncea L. than the unplanted soil indicating that Brassica juncea L. was useful for phytoremediation of soils contaminated with atrazine

5 Precision farming: The most scientific and modern approach to sustainable agriculture, Patil Shirish S and Satish A Bhalerao
Precision farming nowadays is an emerging area in agriculture which has a basic goal to maximize output (i.e. crop yield) while minimizing input (i.e. fertilizer, pesticide, herbicide etc) Precision farming can be defined as application of a holistic management strategy that uses information technology to bring data from multiple source to make decision associated with agricultural production, marketing, finance and personnel. The main objectives of precision farming are to increase production efficiency, to improve to improve product quality, to reduce environmental degradation, to conserve energy and protection of soil & ground water. Key components of precision farming are: Information, Technology and Management. Precision farming technologies are classified in to five major groups: Computers, Global positioning system (GPS), Geographic information system (GIS), Sensors and Application Control. Precision farming promises higher yields lower input cost by streamlining agricultural management and thereby reducing the waste and labour. It also helps to minimize environmental pollution.
6 Groundwater Quality at Iron Ore Mines, Indiag: The most scientific and modern approach to sustainable agriculture, Verma SR, Chaudhari PR, Singh RK and Wate SR
The impacts on water environment are inherent part of any major developmental projects in two ways: one is stress on water resources (continuous withdrawal of large quantities of water) and the other is pollution impacts through discharge of effluents. Thes e impacts may be on either or both surface and groundwater resources in the project area depending on the specific situation. In the present study, an environmental aspect of tailings ponds of Bolani iron ore mines Orissa, India was studied. The quantity and characteristics of tailings are among the most important determinants of water quality at mine sites. The slime from the tailing pond showed 59% of material of inferior grade (50% Fe content) and 41% of material with higher grade Fe content (above 56% Fe). The tailing pond water was slightly alkaline with negligible nutrient content and the metals like Cu, Cr, Mn & Fe at trace concentration. The potential hazard of ground water pollution due to seepage from tailings pond was studied by Variably Saturated 2-D Flow and Transport Model (VS2DT) and it was found that the pond seepage of iron from tailings pond to groundwater would be negligible even after 3 years. Therefore groundwater would not be adversely affected.

8 Karyotoxicity of fungal metabolites in Trigonella foenum-graceum L., Bhajbhuje MN
Fungal metabolites are known organic compounds produced by diverse group of fungal organisms in infested host tissues as well as in nutrient growth medium, of them primary metabolites induce growth stimulating response while secondary metabolites appear to create disturbances in normal cell metabolism, growth and karyokinesis in mitotic cell cycle of metabolically active meristematic cells causing cytological abnormalities. The metabolites produced in growth nutrient medium at different growth intervals by Alternaria alternata (Fr.) Keissler, a serious causal pathogen of leaf spot of Trigonella foenum-graceum L, were isolated, confirmed their chemical nature and evaluated for their cytological effects on metabolically active cells of meristematic zone of roots for cultivars, Kasuri and Kranti. An increase in per cent seed germination and seedling emergence without any abnormalities over control were recorded with five days old metabolites treated seeds. The seed germination rate and seedling emergence declined while percent abnormalities increased with metabolites of longer duration. The metabolites from five day old culture filtrate served as growth promoter while metabolites of longer duration as growth inhibitor. The meristematic cells of the root from treated seeds were reported to multiply abnormally due to appearance of many abnormalities such as Anaphase Bridge, laggards, diagonal metaphase and mis-orientation of mitotic spindles. The metabolites responded uniformly in both the cultivars with the parameters undertaken. The U.V. absorption spectrum TLC and phytochemicals tests for isolated toxins confirmed phenolic in nature.

Plants derived bioactive compounds have been the focus of recent research due to their health promoting effects. There is continuous and urgent need to discover new antimicrobial compounds with diverse chemical structures and novel mechanism of action because there has been an alarming increase in the incidence of new and re-emerging infectious diseases. Phytochemicals have great potency as antimicrobial agents. The present investigation was carried out to assess the qualitative phytochemical analysis of leaves of five medicinal plants i.e. Phyllanthus amarus, Clerodendrum viscosum, Ailanthus excelsa, Syzigium cumini and Cassia occidentalis by using polar solvent methanol, non polar hexane and aqueous extract. The phytochemical screening of plant extracts revealed the presence of steroids, Saponin, alkaloids, flavonoids, glycosides, phenolic compounds, tannins, terpenoids and lignin. These phytochemicals have potent antimicrobial efficiency against selected infectious micro-organisms.
10 Assessment of water quality of Libri River, Purnia (Bihar), Mishra AK and Hasan S
Physico-chemical parameters of river Libri of Koshi zone, Purnia were investigated during March 2009 to February 2010. The result revealed well defined seasonal variation. Relatively high temperature, high value of dissolved oxygen and highest production range of alkalinity were observed which are favorable factors for the production of air breathing fishes. On the basis of studied parameters the river water appears to be of moderate trophic level and hard types. On the whole river is getting pollute due to intense human activities and influence infusion of foreign materials from the surroundings. These materials mainly comprise of decomposable organic matters of plants and animals, terrestrial washing and effluents. A large number of dead bodies are burnt on the bank of the river areas using fire wood and thus formed ashes containing huge quantity of minerals and half burnt flesh content are scattered into the river. This causes nuisance in the river water environment and raises a number of water pollution problems. Thus this water neither can be used for irrigation for crop fields nor for bathing can cattle drinking purposes.

12 MODERN BIOTECHNOLOGICAL APPROACHES IN INSECT RESEARCH, Diganggana Talukdar
To meet the growing demand for food it is essential to increase the production of food. Insect pests are major constraints to global production for food and fibre that can be reduced utilizing modern biotechnological tools. In insect research field, the biotechnological tools have been applied to study various issues such as insect identification, insect control and insect genetic relationships. It has a significant role in improving efficacy, cost-effectiveness and in expanding the markets for the bio insecticides. Molecular techniques employed for identifying and monitoring establishment and dispersal of specific biotypes of natural enemies. Production, formulation and storage of entomopathogenic fungi can be dramatically improved through biotechnology and genetic engineering. Proteinaceous insect toxins (scorpion toxin, mite toxin, trypsin inhibitor), hormones (eclosion hormone, diuretic hormone) and metabolic enzymes (juvenile hormone esterase) introduced into NPV and GV genome virus to increase its efficacy to kill insect. Genetic manipulation of Bacillus thuringiensis (Bt) genes encoding for proteins toxic to insects offers an opportunity to produce genetically modified strains with more potent and transgenic plant expressing Bt toxin. In 2011, planting of Bt cotton in India surpassed the historical milestone of 10 million hectare for the first time and occupied 88% of the recorded 12.1 million hectare cotton crops. However, field resistance of Bt crops to various insects have been noticed and to combat this problem two approaches namely refuge and pyramiding were recently introduced. The development of cryobiological method for preserving embryos of insects can significantly save the rearing costs, and the valuable collection of insect natural enemies could be maintained indefinitely. RNAi technology enables engineering of a new generation of pest-resistant GM crops. Insect control strategies that integrate advance knowledge in biotechnology with traditional wisdom and technology will contribute to the sustainability of agriculture.
