1 Natriuresis does not account for urinary concentration inhability in the chronically undernourished rat. , Edinéia Goedert, Ana Durce Oliveira da Paixão, Carmen de Castro-Chaves.
Through different concentrations of sodium in the diet, we investigated whether the natriuresis observed in the DBR rats since weaning resulted from the higher Na + intake or from its lower conservation by the kidney and its effect on the urinary concentration. For this purpose, we used a multicentre diet, locally called the regional basic diet (DBR) and 60 male Wistar rats, treated from weaning with: (i) control diet, by the American Institute of Nutrition (AIN); ii) DBR supplemented with low Na + content (0.06%), the DBR group; (iii) DBR supplemented with normal Na + content (0.3%), the DBRnorm group; iv) DBR supplemented with high Na + content (3.12%), the DBRhiper group. The excretion capacity in relation to sodium intake was similar between these two groups (99.01 ± 0.12 vs 99.02 ± 0.17%). Malnutrition compromised the urinary concentration mechanism.
2 Contagious Ecthyma of Sheep and Goats: the disease and its vaccine , Jailson Honorato, Raimundo Vicente de Sousa, Roberto Soares de Castro
Contagious ecthyma (CE) is an acute viral disease that affects sheep and goats, widespread throughout the world, including Brazil, especially in the Northeast, where sheep and goat rearing is practiced for the production of skin, meat and milk. In the state of Pernambuco, has been reported as one of the major infectious diseases of goats and sheep in semi-arid. Despite the endemicity of the disease and its importance, few research studies have been conducted in the country with the virus CE, that can support the control of the disease, grounded mainly on vaccination of animals. CE is a disease that can be confused with the vesicular such as Footh and Mouth Disease, with the need for differentiation, especially to support the actions of the National Program for the Eradication of Footh and Mouth Disease (PNEFA) of the MAPA.

6 Specificity of Disonycha glabrata (Coleoptera: Chrysomelidae) in caruru and sweet potato genotypes , Mychelle Pires Barbosa, Elias Correa de Freitas Neto, Alexandre IA Pereira, Carmen RS Curvêlo, Gilberto S Andrade, Luiz Leonardo Ferreira
This study aimed to test the feeding preference of Disonycha glabrata (Fabr.) (Coleoptera: Chrysomelidae) between amaranth plants and different genotypes of sweet potato in field and laboratory. Disonycha glabrata demonstrated specificity to the amaranth plant in multiple-choice tests, gained weight with this diet in nonchoice tests and it was found, under field conditions, constantly on this weed host compared with the ten genotypes of sweet potato evaluated. The results indicate that this chrysomelid might be a future candidate for biological control programs of amaranth plants, although further research should be conducted to assess the real potential of this insect as a biological control agent of weeds.
7 Economic and productive feasibility of pasture cattle supplementation in the dry season , Eduardo Gabriel Galavotti, André da Cruz França Lema
The aim of this paper was to evaluate technically and economically non-castrated male cattle performance, supplemented with proteic salt grazzing Brachiaria brizantha cv. Marandu in the dry season, in the northwest region of São Paulo State. The average weight gain was 25.78 kg animal-1 . The average costs were R$124.10 animal-1, which had a profitability of R$0.45 animal-1. Despite small profits, the supplementation allowed to accelerate the productive cycle, since the animals gained weight and were slaughtered right after the end of supplementation intake, thereby lowering the slaughtering age, time and the animal cost in the property.
8 Organisms that host Tetrodotoxin and researches related to its medicinal use , Diego Carvalho Viana, Jorge Diniz de Oliveira, Luís Miguel Lobo, Rennan Lopes Olio, Alanna Carla Farias Couto, Francisco Eduardo Aragão Catunda Junior, Amilton César dos Santos
Tetrodotoxin (TTX) is a highly important animal toxin found in pufferfish, mollusks, arthropods, flatworms and amphibians. Although the toxin is related to several cases of food poisoning in humans, recent search demonstrated that TTX has a potent specific action in the blockage of voltage-gated sodium channels (VGSCs). The aims of current research is demonstrates that TTX is efficient in therapies related to the nervous, circulatory and motor systems, besides those against cancer. TTX-producing organisms, its mechanism and studies on the therapeutic use of the toxin in medicine are provided. Further studies may reveal other therapeutic uses of TTX related to voltage-gated sodium channels due to its efficiency and specificity in the blockage of these channels.

The incidence of tuberculosis lesions in cattle slaughtered in Espírito Santo was 0.23% and varied among study regions from 0.04% to 0.44%, being higher in the south of the state (44%). Muqui stood out as the municipality where it has a greater occurrence of injuries (1%) and the greater relative risk. The results evidenced the necessity of elaboration and adoption of measures according to the intrinsic characteristics of each region.
15 , Erosion and economic valuation of nutritional supplementation in cultivated soil with burned and nonburned sugarcane in Campos dos Goytacazes – RJ
The efficiency of Brazil in the production of sugar and ethanol is unquestionable, however, the challenges still remain for the management of the burning of the straw in the pre-harvest of sugarcane, which has generated negative externalities. Water erosion is one of the most aggressive forms of environmental degradation and which has caused huge losses. This work was carried out in the municipality of Campos dos Goytacazes, RJ, Brazil, in order to estimate soil erosion losses in an area planted with sugarcane under two types of crop management. The Universal Soil Loss Equation (EUPS) was used to obtain the erosion rates and the Replacement Cost Method (MCR) to carry out the economic valuation of the ecosystem service.The results show that the rate of soil loss from sugarcane burned was four times greater when compared to the rate for sugarcane harvested raw for both areas studied. The replacement cost of lost nutrients in the cultivation of sugarcane under harvesting system with previous burning was R$6.73 and R$15.91 per hectare of lowland and coastal tableland, respectively, while in the sugarcane harvesting unburned system the cost per hectare was R$ 1.66 for the lowland and R$ 7.56 per hectare for the coastal tableland. It is concluded that the crop management system influences environmentally the preservation of soil fertility and the cost of fertilization of the crop.
16 Sanity, germination and vigor of creole bean seeds submitted to chemical and biological treatment , Diego Trentin, Daiani Brandler, Silvionei Webber, Maurício Albertoni Scariot, Paola Mendes Milanesi

21 Monitoring of soybean grains (Glycine max L. Merril) stored in metal silos , Letícia Almeida Sorano, Rienni de Paula Queiroz, Guilherme Araújo Brustolin
The main post-harvest concern is with the processing and storage, which plays a fundamental role, since they seek to guarantee the quality of the product that comes from the field. The storage process is the activity that stores and conserves the grains, aiming to guarantee the quality of the product regardless of the time it is kept in storage (BROOKER, 1992 apud LIMA, 2013). The objective of this work is to monitor the classification, temperature and humidity of soybeans at the Coopergrãos Cooperative, located in Nova Andradina – MS, and how these variables interfere with the quality and longevity of grains stored in silos. The temperatures were obtained through thermometry performed with the Thermo Collector MOD. V5 FOCKINK, where weekly temperatures during the months of May, June and July were monitored for each cable and its respective sensors. During this monitoring period, two samples of soybean grains were collected on different days in June to gauge moisture. The samples were withdrawn with the interval of 20 minutes to representatively express the material present in the silo, and were collected at the end of the conveyor belt. There was no proliferation of microorganisms or insect pests, where the grain mass did not present favorable humidity and the temperature was below the optimum for its proliferation. In the classification, we found the total number of defects above the allowed for soybean, but it was framed as Out of Type which does not prevent the sale of grains for other uses in the commercialization.
22 Physiological and phytosanitary quality of treated seeds of Eugenia dysenterica DC. during storage , Évelin Cristiane Castro Silva, José Carlos Moraes Rufini, Nádia Nardely Lacerda Durães Parrella, Wânia dos Santos Neves
This study analyzed the physiological quality and plant in Eugenia dysenterica DC seeds. The treatments were control, drying, fungicide Cercobin® and thermotherapy. It was identified the genus Aspergillus, Fusarium, Penicillium and Rhizopus associated with seed treatment used as a witness. Drying was not an effective phytosanitary control and caused damage to the physiological quality of seeds. The fungicide was more efficient in the seeds prior to storage. Treatment with thermotherapy annulled the presence of Aspergillus and Rhizopus after 100 days of storage and did not cause significant losses in seed quality when compared with fungicide and witness.

Several researches confirm the existence of a high relationship between the magnetic field and many biological processes at cellular scale. There are several methodologies of micro-propagation, however, the obtained results in the acclimatization phase, are not yet desired. The objective of the present study was to characterize the quality of the stomata of vitroplants of pineapple during the acclimatization phase and to evaluate the influence of irrigation with magnetically treated water (MTW) six months after the acclimatization. The magnetizer employed had an induction level of 50-70 mT. When evaluating the results, it was observed that the stomata conserve its anatomy while increasing the stomata and stomatal opening area values, with 64x103 stomata mm-2 in the treated pineapple vitroplants compared to the untreated ones, that presented 61.6x103 stomata mm-2; as well as, also presented 3.06 μm2 of stomatal opening area, in relation to the untreated ones that presented 2 μm2 . These results show the ease of treatment and the potential of MTW technology as an effective management via in the acclimatization areas of plants produced “in vitro”.

41 Productivity of gherkin cultivars in different cropping systems , Herodilson Guimarães da Costa, Ana Francisca T. A. Ferreira e Ferreira, Hiroshi Noda, Jânia Lília da Silva Bentes
Gherkin is a very consumed vegetable in the North and Northeast of Brazil, and over the years it has been cultivated bythe family farmers in a traditional way, with the fruit in contact with the soil, which induces the commercialdepreciation of the fruits and the frequent occurrence of diseases. Several techniques have been implemented for thecultivation of fruit vegetables, being the tutoring one of the most used, for promoting the increase of productivity and toimprove the quality of the fruits. The objective of this work was to evaluate the productivity of three cultivars ofgherkin (North, Northeastern and INPA) in three (undergrowth, in vertical stake and espalier) in the dry and rainyseason in Amazonas. Parameters related to weight, length, diameter and number of fruits were evaluated, andproductivity was estimated. However, the best quality of the fruits was obtained in the cultivation with espalier. Amongthe cultivars, INPA presented the best performance. The period of drought was the one that favored the production andquality of the fruits of maxixe, which is recommended for the planting of this crop in the state of Amazonas.

Contagious ecthyma is a severe and proliferative viral disease affecting ovine and caprine species, and eventually men,caused by the contagious ecthyma virus (ECV) of the Parapoxvirus genus. The disease is spread worldwide, includingin Brazil, where in the state of Pernambuco, due to its endemicity, can be mistaken by other vesicular diseases such asthe Foot and mouth Disease, which requires its diagnostic differentiation. Meanwhile, the control of the infection inendemic regions is limited due to the difficulties in replicating the virus in cell cultures, for the development of vaccines.
49 Urospermia in horses , Jailson Honorato, José Adalmir Torres de Souza, Deyse Naira Mascarenhas Costa, Diego Carvalho Viana
Contamination of the raw semen with urine can result in irreversible damage to the semen. The sensitivity ofspermatozoa to osmotic damage differs markedly between species. Urospermia has been associated with intermittentsubfertility and infertility in the horse. The cause may involve failure of the bladder sphincter occlusion and a functionaldisorder in the components of the autonomic sympathetic and parasympathetic autonomic nervous system that controlurination, erection, and ejaculation. Few studies have been done reporting the effects of urospermia on changes in pH,osmolality and motility of equine semen, but it has been reported in the literature that a urospermic condition leading toa hyperosmolar solution is detrimental to sperm motility in horses.

64 Occurrence of noni anthracnose caused by Colletotrichum siamense in Amazonas, Brazil. , Blenda Naara Santos da Silva, Ana Francisca Tibúrcia Amorim Ferreira e Ferreira, Adolfo José da Mota, Jânia Lília da Silva Bentes
Noni (Morindacitrifolia L.) is native fromSoutheast Asia and was introduced in Brazil recently, where it haswelladapted to the edaphoclimatic conditions.Thefruits are consumed because of their numerous therapeutic properties.FromMarch to November 2018, circular brown spotswith concentric rings were observed on leaves of noniplants,atFederal University of Amazonascampus(UFAM), wherethe temperature and rainfall ranged from 23°Cand 32°C, and 47mmand 335mmin this period.Leaves with typical symptoms of anthracnose were taken to the laboratory and washed with tap water. Fragments (5 mm) were removed from the margin of leaf lesions, superficially disinfested with 70 % alcohol(1 min.) and1,5 %sodium hypochlorite (1 min.) followed by three washeswith distilled water, dried on filter paper and plated in Petri dishes with Potato Dextrose Agar(Kasvi). Plates were incubated at 25 °C.After 48 h, mycelial fragments were transferred to new PDA plates and incubated at 25 °C under fluorescent light (T8 tubular lamps, 40 w, 6400k daylight), located 25 cm above the plates.Morphological characteristicswere observed after 7 days.Colonies were light grey to white and orange conidium masses in the center. Reverse of the colony wasorange to white(Figure 1A).Conidia were hyaline, aseptate, oblong-elliptical and 5.75to 8.26× 1.82to 2.39μm (n= 30) (average ± SD = 7.09± 0.51× 2.09± 0.17μm). The morphological characteristics were similar to Colletotrichumsiamenseinto Colletotrichum gloeosporioides speciescomplex (Sharma et al., 2015; Weir et al., 2012). The 3 Kbp ribosomal, beta-tubulin2(TUB2)and glycerol-3-phosphate dehydrogenase(GAPDH)sequencing (acession number: MK299421, MK821246, MK821247)was carried out using NS1-NS8, ITS1, ITS4,Uni-R primers,T1-T2 and GDF-GDR(White&Lee, 1990; Fell,1993; O’Donnell& Cigelnik 1997; Templeton et al., 1992). Maximum parsimony phylogenetic tree (MEGA v. 7.0)fed with Colletotrichumsequences from noni and the reference isolates of Colletotrichumspp. deposited in GenBank, revealed that the isolate belonged to C. siamensespecies. The pathogenicity test was conducted with healthy noni leaves. The leaves were washed and disinfected superficially. Leaves wereinoculated with mycelial discs and with agar discas a control. Typical anthracnose lesions were observed on noni leaves after 7 days (Figure1B). C.siamensewas reisolated from the lesions, and their identity has been confirmed asdescribed above.Colletotrichumspecies is also responsible for anthracnose of M.citrifoliain the Brazilian statesofGoias, Mato Grosso andCeara. In countries like Mexico and India, anthracnose causes significant losses in noni culture (Ayvar-Serna et al., 2018; Hubballi et al., 2010). To the best of our knowledge this is the first report of C. siamense anthracnose of leaf noniin state of Amazonas (Brazil).

This study was to evaluate the propagation by cuttings treated with auxins, indolebutyricacid (AIB) and naphthaleneacetic acid (ANA) at concentrations of 0, 1000, 3000, 5000 and 7000mg.L-1. The apical and basal cuttings were used in an intermittent nebulization chamber, with 70% luminosity, for a period of 180 days. It was observed that the rooting of apical and basal cuttings is dependent on the application of IBA, and the highest percentage of rooting was obtained in the highest concentration of IBA and ANA (5.000 mg L-1) with rooting percentages of 30, 25% and 33,33%, respectively. Forthe mean number of roots and root length, the best results were obtained in the concentrations of AIB and ANA (5.000 mg L-1). In this sense, there is the potential for propagation of the jabuticabeira by the cutting method.
77 Test Allium cepa as indicator of genotoxical activity of the aveloz Euphorbia tirucalli , Maria Clara Moreira Maia, Caroline Martins Rocha, Tatielle Erins Santos, Janini Tatiane Lima Souza Maia, Priscila Regina Queiroz, João Paulo Gomes Oliveira
The objective was to identify the genotoxic activity of the aveloz, using the Allium cepa method, adapted methodologies applied in scientific literature. The experimental design was a completely randomized design with five treatments: five distinct concentrations of latex: 0; 0.15; 0.50; 0.75 and 1mLL-1, with five replicates. After germination of the onion bulbs, slides were prepared with meristems and examined under an optical microscope. The applied treatments contributed to the presentation of two types of cellular aberrations: binucleate cells and bridges in anaphase and telophase. Further studies are needed to better assess the potential risks of the mutagenic agents present in hazelnut latex, as well as to adjust the methodology used.

The objective of this study was to evaluate the influence of four levels (0, 10, 20 and 30%) of inclusion of wet brewery residue (RUC) on diets for sheep on their ingestive behavior. A 4 x 6 factorial design was used, with six evaluation times. Continuous activities (feeding, rumination, other activities and leisure) and punctual (salt intake, water intake, urination and defecation) were evaluated, as well as food behavior variables. From the inclusion level of 10% of the RUC, an effect (P <0.05) was observed for rumination, other activities and leisure time. The period of the day had an influence on all the behavioral variables studied independently of the inclusion level of wet brewery residue, being the 20% level with the best results.
81 Gene action antibiotics used by rural producers in the municipality of Senador Rui Palmeira –Alagoas , Evandro dos Anjos Machado, Cláudio Galvão de Souza Júnior
This work investigated the most used antibiotics withgene action by rural producers in the municipality of Senador Rui Palmeira, an important center for the immediate geographic region of the Médio Sertão from Alagoas, northeast of Brazil. Semi-structured interviews with cattle rancherswas realized. There has been widespread use of tetracyclines over other antibiotics. Among the chemotherapeutic classes identified, the one of interference in the protein synthesis was the most used. The characterization of the profile of the classes of antibiotics marketed and consumed in this productive center of regional importance should contribute to more advanced studies on livestock development programs and prevention of the growth of resistance to antibiotics.
82 Current scenario of milk active in the rural properties of Presidente Figueiredo, Amazonas, Brazil , Ytaiara Lima Pereira, Mariana Silva Albuquerque, Francisco Martins de Castro, Luiz Aldiney Alves de Oliveira, Paulo Cesar Gonçalves de Azevedo Filho, Jomel Francisco dos Santos
The objective was to characterize the current dairy cattle production of Presidente Figueiredo-AM. In the period from 2017 to 2018, 11 active dairy farms were visited. 57.4% of the producers stated that they only performed one milking daily, justifying this practice due to the low productivity of the animals, on average 40 liters / day. 81.82% of the interviewees know the IFAM, however, all the interviewees havenot yet participated in any action promoted by the institute. Dairy farming in Presidente Figueiredo is characterized by low production and low technology. Most of the producers are new to the activity and require technical instruction to improve sanitary, reproductive, nutritional and milking management to leverage better dairy production results.
83 Economic losses of pre-slaughter management lesions in cutting cattle , Lucas Gomes da Silva, José Eduardo Lippi, Luiz Carlos Pereira, Rafael de Oliveira Lima, João Victor de Souza Martins, Rafaela Thais Benedito Alves, Alexandre de Oliveira Bezerra, Rodrigo Gonçalves Mateus
The objective was to identify and evaluate economic losses due to carcass lesions, with different pre-slaughter cattle management, where 60 male Nelore no-castrated subdivided into treatments by management and transportation. The truck transport with rational management presented smaller injuries and better financial positioning when compared to the cart. Among the management, the rational excelled with minor injuries. The most incident site of injuries was in the rear and numerically considerable in the carriage truck. It is extremely important to rationalize the management throughout the process called pre-slaughter and choose the appropriate transport, minimizing losses due to carcass lesions, increasing economic viability.
84 Serum biochemistry and carcass of broilers, in natural heat conditions, supplemented with organic zinc and vitamin E , Jackelline Cristina Ost Lopes, Jefferson Douglas Martins Ferreira, Agustinho Valente de Figueirêdo, João Batista Lopes, Sidclay Ferreira Maia, Mabell Nery Ribeiro, Vânia de Sousa Lima Aguiar
The objective of this study was to evaluate the effect of organic zinc and vitamin E on diets for broilers exposed to naturalcyclic heat conditions, from 1 to 21 days of age, on carcass and cut yield, skin resistance and serum biochemistry. A total of 600 male and female Ross 308 chicks were used and distributed in a completely randomized design in a factorial scheme. The treatments consisted on inclusion of organic zinc (0 and 120 mg/kg) in association with vitamin E (0, 300 and 600 mg/kg) in the birds' diets. The carcass yield was higher with 120 mg of organic zinc/kg when compared to the treatment without the mineral. Serum triglycerides decreased with 300 mg and 600 mg of vitamin E supplementation. There was interaction between the levels of zinc and vitamin E promoting the fall of blood albumin levels. Organic zinc provides higher carcass yield and vitamin E, associated or not with zinc, improves the serum biochemistry of broiler chickens under natural cyclical heat conditions up to 21 days of age.

86 Canine atopical dermatitis –literature review , Breno Henrique Alves, José Antônio Viana, Natália do Prado Alves e Rodrigues, Ana Luiza de Pádua Pristo, Lauren Silva Maia, Shayene Mara Vaz da Silva, Thaís Rosa Rodrigues da Cunha
Canine atopic dermatitis (DAC) is an allergic, inflammatory, pruritic, allergic skin disease, with very characteristic clinical features. It is directly associated with IgE (immunoglobulin E) antibodies against environmental allergens. The patient becomes sensitized to such environmental allergens which, in non-atopic animals, no longer cause disease. In addition to genetics, parasitic diseases, viral infections, vaccination with live modified viruses, have been shown to increase the production of specific IgE for environmental allergens, these being other relevant factors in the development of atopic dermatitis, although, although the disease has been related to Some breeds are more predisposed to develop atopic dermatitis such as Lhasa Apso, ScothTerrier, Dalmatian, Miniature Schnauzer, Foxhound, Scoth Terrier, West Highland White Terrier, Shar Pei, Boston Terrier, Pug, Belgian Shepherd, Golden Retriever, Shih Tzu, Labrador, English Setter, Boxer. Canine atopic dermatitis may also affect mongrel dogs (Undefined). The age at which clinical signs begin to manifest can range fromsix months to seven years, so that 70% of dogs develop AD between one and three years of age.
87 First report of Diaporthe arecae causing leaf spot on Cenostigma tocantinum in Brazil , Blenda Naara Santos da Silva, Nonato Junior Ribeiro dos Santos, Sulianne Idalior Paião Rosado
The forest species popularly known as “pau-pretinho” (Cenostigma tocantinum Ducke) is one of the most used in urban arborization of the municipality of Manaus, Amazonas (Brazil). It is a native species to the Amazon and has low susceptibility to attack by pests and pathogens. Throughout the year 2018, symptoms were observedon the leaves positioned in the lower third of the crown of C. tocantinum trees. The symptoms were characterized by areas of light brown color in the center and dark brown edges observedon leaves. The symptomatic trees were locatedon campus of Federal University of Amazonas (UFAM), in Manaus, where the temperature and rainfall ranged from 24°C to 33°C, and 113 mm to 335 mm in this period. Small fragments (2 to 3 mm) of symptomatic leaf tissues were surface disinfested, plated on potato dextrose agar (PDA) amended with 0,25 g.L-1of chloramphenicol, incubated at 25°C and hyphal tips were transferred to fresh PDA plates. No presence of conidia in PDA culture medium was observed after 20 days. The pathogenicity test was conducted on C.tocantinum seedlings. Leaves were inoculated with mycelial discs. After inoculation the plants were sprinkled with the mixture of water and fungal mycelium and kept in plastic bags to maintain moisture. The plant control was inoculated with agar disc, sprayed with water, and kept in plastic bags. Symptoms similar to those observed in the naturally infected plant were observed in the C.tocantinumseedlings after 15 days (Figure 2). The symptomatic leaves were placed in a humid chamber and after 48 h spores(measures)were observed at the apex of the conidiomas. The pathogen was reisolated from the lesions, and their identity has been performed by molecular methods. The 3 Kbp ribosomal (SSU, ITS and LSU) and beta-tubulin (TUB2) regions (acession number: MK299422, MN067841), were amplified and sequenced using primers NS1-NS8, ITS1, ITS4, Uni-R primers and T1-T2. Concatenated phylogenetic analyses based on maximum parsimony(MP) analyses using MEGA7 with our sequences and reference isolates of Diaporthe spp. showed high similarity with the sequence of Diaporthearecae (CBS 161.64). To the best of our knowledge this is the first report of Diaporthe arecae causing leaf spot on C. tocantinum in Brazil.
88 Phosphorus sources: effects on mahogany nursery trees , Nonato Junior Ribeiro dos Santos, José Zilton Lopes Santos, Carlos Alberto Franco Tucci, Bruno Fernando Faria Pereira, Arnon Afonso de Souza Cardoso, Elias Paiva Farias, Tainá Azevedo de Jesus
Questions persist regarding the best phosphorus (P) sources for tropical soils, especially for forest species. We evaluated the effects of four different P sources (single superphosphate -SSP; triple superphosphate -TSP; Arad reactive rock phosphate-ARP and Yoorin thermophosphate -YT) on nutrients accumulation, phosphorus use efficiency and growth on mahogany (Swietenia macrophyllaKing.)Mahogany is responsive to P fertilizer, however the high water soluble(TSP and SSP)and citric acid (YT) phosphorus sources had a similar effect on mahogany growth. It suggests that the seedlings producer can use any of thembut should avoid the use of the ARP source in this stage of plant growth.

The objective of this work was to evaluate the reaction of chickpea genotypes to the Embrapa Vegetables germplasm bank for resistance to Meloidogyne incognitarace 1 and M. enterolobii, aiming to identify sources of resistance to these root knot nematodes,and to verify haw this culture is affected byM. enterolobii. Six genotypes of chickpea were evaluated: 'Jamu-96', 'Flipoz-23C', 'Flip 03-34C', 'Flip06-155C', 'FIip03-109C' and the cultivar BRS Cícero. The experiment was conducted in a completely randomized design in a 7x2 factorial scheme (seven genotypes x two species of nematodes), with six replications. The two nematodes species were inoculated in the chickpea genotypes, and 104 days after inoculation were evaluated the egg mass index (IMO) and gall index (IG), number of eggs per gram of root (NOGR) and of the reproduction factor (FR). The data were submitted to individual and joint analysis of variance for the two species of nematodes and grouping of means of the treatments by Scott-Knott test. Was verified that for both species root-knot nematodes were not possible to identify resistant chickpea genotypes, but as field control is difficult, researches such as these to search for sources of resistance are important.
94 Consortium of culture of corn with forage plants , Altamir Matias Pimenta Neto, Ariel Muncio Compagnon, Guilherme Santos Ventura, Fernando Henrique Arriel,  Murilo Lopes dos Santos
The objective of this work was to evaluate the phytotechnical characteristics and corn productivity in a consortium with forages, in different sowing modalities. It was evaluated: dry matter of corn plant, forage and total straw, plant heights, stem insertion, stalk diameters, ear and cob, number of rows of grains, ear masses, ear grains, ear corn, 1000 grains and productivity. The corn consortium with Urochloasdid not change the phytotechnical characteristics compared to single corn. As there were no differences in productivity, the modalities of sowing in the line (seed mixed with the fertilizer) are a good alternative, since they reduce operational expenses.

The objective of the present work was to define the dose of N in the necessary cover to the greater development of the cultivated Vanda cultivar. Five treatments, doses of Napplied in a cover (0, 30, 60, 90 and 120 kg ha-1)and four replicates, were given in equal dosesat 10, 20, 30 days after transplantation (DAT). Harvest was carried out at 60 DAT where they evaluated: leaf number, plant height, leaf width, leaf length, plant width, stem diameter and total productivity. The 98.5 kg ha-1dose of N in cover fertilization provided a better development in field cultivated lettuce.
96 Emergency and initial growth of guandu beans in the function of substrates and salinity of irrigation water , Beatriz de Abreu Araújo, Francisco José Carvalho Moreira, Fernando Lisboa Guedes
One of the factors of greatest concern in current agriculture is the salinization of soil, especially irrigated land, with inadequate management of irrigation and fertilizers used in agriculture, one of the main determinants responsible for increasing the area with degraded soils. In the northeastern wilderness, evapotranspiration overcomes precipitation and, as a consequence, makes it impossible to percolate the water through the profile and, consequently, does not result in the leaching of soil salts. Considering the conditions present in the northeastern semi-arid region and the problems caused by salinization of soils, the present study had the objective of evaluating emergence and initial growth of pigeon pea as a function of two substrates and irrigation water salinity levels. The experiment was conducted at Green House, at the Federal Institute of Education, Science and Technology of Ceará -CampusSobral. The experiment was conducted in a completely randomized design (DIC), in a 5 x 2 factorial scheme, with five salinity levels (0.27, 1.5, 3.0, 4.5, 6.0 dS m-¹), and two types of substrates (sandy and clayey), with 4 replicates of 18 seeds each. The Analysis of Variance (ANOVA) was performed using the statistical program R Development Core Team (2011). According to the results observed in the trial, the cultivar BRS Mandarim obtained a higher survival rate, with the increase of the level of salinity in clayey substrate; All variables analyzed were influenced by treatments; the cultivar normally germinated up to the level 3.0 dS m-1, behaving like a plant with moderate capacity of tolerance to the salinity.

The experiment was a split plot scheme in a randomized complete block design. The plots treatments were the densities and the subplots were the weed control methods. The BRS Arace populations that maximized the interception of irradiance were 166,667 and 181,739 plants ha-1, before flowering and during the full bloom, respectively. The highest numbers of pods per plot and grain productivity were found in the populations of 128,000 and 121,000 ha-1plants in BRS Arace.
98 Development and production of BRS quênia grass submitted to nitrogen fertilization doses. , Fernando Luiz Silva, Karoline Jenniffer Heidrich, Marcus Henrique Martins e Silva, Samoel Oliveira de Castro, Soraia Olivastro Teixeira
The objective of this work was to evaluate the growth and productivity of BRS Quênia grass (Panicum maximum) submitted to nitrogen fertilization in Alta Floresta, MT. The highest dry matter yields occurred at doses 150 and 300 kg ha-1. It was observed the occurrence of green leafhopper (Empoasca kraemeri) in the final period of the experiment. The BRS Quênia grass, under the conditions of the experiment, presented a high response to nitrogen fertilization. The dose of 150 kg of N ha-1is recommended. Further studies are suggested to verify the susceptibility of BRS Quênia grass under the occurrence of the greenleafhopper (E. kraemeri) and to identify the best conditions for the maximum performance of this forage in the region.
99 Concentration of hydrocyanic acid in fresh and conserved maniçoba , Tomás Guilherme Pereira da Silva, Adriana Guim, Cíntia Rafaela de Lima Costa, Carlos Henrique da Silva Mendes, Levi Auto Lopes, Edwilka Oliveira Cavalcante, Júlio Cézar dos Santos Nascimento, Bruno Leal Viana
The objective of this study was to quantify the concentration of hydrocyanic acid (HCN) in the morphological components of fresh maniçoba at different ages of growth and conserved as hay and silage. At the 30th day, the highest HCN values were found in all morphological components and at all ages the HCN concentrations were higher in the leaf. Silage and hay processes promoted a decrease of 67.03 and 91.15%, respectively, in the HCN values in relation to the fresh plant. Maniçoba leaf have a higher HCN content, especially when younger. Forage conservation methods reduce the concentration of HCN in maniçoba.
100 Effects of temperature, rainfall and drought on cassava productivity parameters in southern of Santa Catarina, Brazil , Augusto Carlos Pola, Alexsander Luis Moreto, Eduardo da Costa Nunes
The interrelations between the number of tuberous rootper plant, yield and dry matter content of roots of the Mandim Branca cultivar in 19 years of cultivation were evaluated, as well as the simple linear correlations of these variables with meteorological elements and droughtin Jaguaruna, SC, Brazil. The three productive variables presented statistically significant correlations (p <0.05), positive and moderate among them. Mean temperature and precipitation presented negative and moderate correlation coefficients with yield and dry matter content. The maximum temperature presented a direct relation with the three productive variables. The number of tuberous roots per plant showed positive and strong correlations with maximum temperature and negative with drought duration in the first five months after planting. The duration of drought showed an inverse relation with the three productive variables. The results indicated that both water deficiencies and high precipitation in the post-planting period may decrease cassava productivity under the edaphoclimatic conditions of the present study.
101 Doses of potassium fertilization in arugula (Eruca sativa L.)culture in soil with mean potassium availability , Natália Barreto Meneses, Letícia Serpa dos Santos, Fabricio Simone Zera, Francisco Soler-Neto
This work aimed to evaluate the interference of doses of potassium in arugula culture. The experiment was conducted in a rural property in Borborema-SP. A randomized complete block design with five treatments (0; 50; 100; 150 e 200 kg ha-1de KCl)and four replications was used. Were evaluated Dry mass (g); Root size (cm); Number of sheets. There was no significant difference between the treatments and the control in any parameter evaluated. It is concluded that the supply of this nutrient via fertilization does not provide increases in arugula productivity.

141 Tomato nutrition and initial growth: acid-calcium interaction , Bruno Paulo Moschini, Carlos Alberto Silva
The objective of this study was to evaluate the nutrition and the growth of the tomato as a function of the concentrations of carbon-humic acid (C-HA) and its interactions with sources of calcium (Ca). The experimental design was a completely randomized design, in a 2x5 factorial scheme, where two sources of Ca: calcium carbonate (CaCO3) and calcium sulfate (CaSO4) were combined with four concentrations of C-HA (5,10, 50 and 100 mg kg-1of soil), in additionto a control treatment, in three replicates. The dry matter (DM) of shoot and roots, the availability of Ca in the soil and the concentration of macro and micronutrients in shoot were evaluated. The tomato plants produced more DM when the CaCO3was used. The accumulation and concentration of nutrients were not affected by the addition of C-HA; however, the nutritional state of the tomato is regulated by the source of Ca used.
