| ABSTRACT: The bean (Phaseolus vulgaris L.) is one of the most important constituents of the diet of the population, has an excellent protein source, but their income is low due to diseases such as common bacterial blight caused by Xanthomonas axonopodis pv. phaseoli. The aim of this study is to test the influence of foliar fertilizers in disease severity. For this purpose, bean plants were grown in a greenhouse and in the vegetative stage V2 applied the treatments with foliar fertilizers CaB (calcium and boron), Mn (manganese) and Z (zinc), and control of water, bactericidal Agrimicina (50 mg i.a.L-1 ) and acibenzolar-S-methyl (75 mg i.a L-1), and three days after the pathogen was inoculated. The bacterial suspension was inoculated at a concentration of 5... |

| The objective was to evaluate the productivity, morphological and chemical composition, in addition to the economic viability of the corn crop (Zea mays L.) for the production of silage under different levels of nitrogen and potassium fertilization in coverage. Treatments consisted of four coverage levels: T1 (217 kg ha-1 N + 137 kg ha-1 K2O); T2 (295 kg ha-1 N + 163 kg ha-1 K2O); T3 (374 kg ha-1 N + 190 kg ha-1 K2O); and T4 (452 kg ha-1 N + 216 kg ha-1 of K2O). It was found that the fertilization level had no effect (P> 0.05) in the parameters related to plant height, height of the first insertion spike and grain production, however, higher (P <0.05) dry biomass production was obtained with 374 kg ha-1 N + 190 kg ha-1 coverage K2O (32,346 kg... |

| ABSTRACT - After harvesting of summer crops and before wheat planting, in the temperate region of southern Brazil, there is a time in which it could be possible grows short cycle cover crops. The objective was to evaluate some cover crop species during this period and its effect on wheat crop. The following treatments, in the years 2011 to 2013, were evaluated: fallow – bare soil (check), sunflower (Helianthus annuus), sunnhemp (Crotalaria juncea), forage radish (Raphanus sativus), pea forage (Pisum sativum) and buckwheat (Fagopyrum esculentum). It was also evaluated the effect of time - 0, 15 and 30 days - between the formation of the mulching and the planting of wheat. In the average of the three years the highest wheat yield was obtained in sunflower... |

| The nitrogen is the most absorbed nutrient by maize, and its supply after seeding is common. However, its available for the plants is associate with soil and weather conditions and with kind of genetic material that is used, due the yield potential and the genetic base. This paper had the aim to evaluate two maize genotype groups at levels of nitrogen in covered, in Gurupi, Tocantins State, Brazil, season 2012/13. The experiments with 30 genotypes had two levels of covered nitrogen (0 and 150 kg ha-1) and they were seeding in two dates. The experiments with 12 genotypes had three levels of covered nitrogen (20; 80; 140 kg ha-1) and they were seeding in four dates. The experimental design was randomized blocks with three replications. For the analysis of... |

| Four types of poly unsaturated fatty acids (PUFA) are essential for all shrimp species, linoleic (LOA, 18:2n-6), alfa-linolenic (ALA, 18:3n-3), eicosapentaenoic (EPA, 20:5n-3) and docosahexaenoic (DHA, 22:6n-3) acids. Moreover, the arachidonic acid (ARA, 20:4n-6), even when present, seems to be, in crustaceans, not so important or yet dispensable. It is relevant knowing that cholesterol as much as PUFA are not well absorbed when not followed by a substantial amount of lecithin, reaching 5% of the ration. The sum of PUFA reaches around 3% of the diet, even varying according to the species, stage and ration type. For Penaeus monodon a complex mathematic model was formulated in order to describe the relationships between the... |

| Common beans are legumes of extreme importance for the food security of developing countries. Because it is widely cultivated in tropical and subtropical regions, it is subject to the stress effects caused by this type of climate, such as water stress and heat. Cross-tolerance allows plants to acclimate to a range of different stresses after exposure to a specific short-term stress. The present work had as objective to evaluate the induction of cross-tolerance by heat stress at 38ºC and water stress simulated by polyethylene glycol (PEG) in 3 different osmotic potentials in the germination of the brazilian cultivars IPR Uirapuru and IPR Campos Gerais in a randomized block design, setting up a 2 x 2 x 3 factorial scheme, with eight replicates of 25 seeds.... |

| As cultivares de mandioca apesar de adaptarem-se aos mais diferentes ecossistemas, apresentam alta interação do genótipo com o ambiente. O seu cultivo restringe-se em grande parte em um sistema de revolvimento solo, que altera as propriedades físicas, química e biológica do solo. Diante do exposto, objetivou-se avaliar cinco cultivares de mandioca em dois sistemas de plantio, direto sobre palhada de aveia preta (SPD) e convencional com revolvimento do solo (SPC). O experimento foi conduzido durante a safra de 2016/2017 em Tuneiras do Oeste (Paraná).

| In recent years, Lasiodiplodia theobromae, has become an important pathogenic agent to many crops. It has been widely spread in all tropical and subtropical regions of the world. The increasing extension of diseases caused by L. theobromae in tropical fruits has caused enormous losses. Therefore, the need for basic knowledge about this pathogen is a must. This study aimed to characterize isolates of L. theobromae, evaluating the cultural aspects and pathogenicity in seedlings of Spondias cytherea in Northeast Brazil. The mycelial growth, colony morphology and pathogenicity of isolates on S. cytherea were evaluated. The results showed variation in mycelial growth and pathogenicity of L. theobromae in S. cytherea. It was also observed that there is a... |

| With the aim of evaluating the time in days to silking, plant height and lodging index of wheat genotypes, an experiment was conducted, in 2012, in the experimental field of Central Cooperative for Agricultural Research (COODETEC) in Palotina (Paraná, Brazil). The experimental design was a randomized complete block design with three replications, involving 15 treatments consisting of three cultivars – CD 150, Frontana and Mirante – and 12 parental lines derived from crosses of the cultivars CD 150 and Frontana. The analysis of variance showed differences among genotypes, indicating the presence of genetic variability for the traits days to silking and plant height. The crosses of CD 150 and Frontana resulted in lines from early to mid life cycle, with... |

| The aim of the present study was to evaluate the potential utilization of DDGS on diet of Nile Tilapia by chemical and digestibility analyses. Firstly, the chemical composition of the ingredient was evaluated and then were made two diets: a reference one and a test diet made of 80% with the reference diet and 20% with DDGS, for the digestibility study. For the faeces collection was used the indirect method, using chromium oxide as an inert marker. After the collection, the faeces were destined to chemical composion analysis and so the experimental diets. With the results, the Nile Tilapia coefficient of digestibility of the DDGS nutrients was calculated. Proteins and total lipids mainly compose the DDGS, which gives its high concentration of crude energy.... |
