25. Growth, fenology and yield of cherry tomato crop in hydroponic cultivation / Crescimento, fenologia e rendimento do tomateiro cereja em cultivo hidropônico
The use of a new production system demand to know the behavior of cultures and establish the most appropriate management. It is necessary to understand the relationships that control the operation of the plant, and then understand the way in which these relations are dazzling together to result in final income. The growth dynamic, the fenological characteriz

27. Desempenho produtivo e reprodutivo e parâmetros sanguíneos de vacas leiteiras alimentadas com diferentes fontes de gordura no período de transição e inicio de lactação / Productive and reproductive performance and blood parameters of dairy cows feeding with different fat sources in transition period and early lactation
This study was carried out to evaluate the use of different fat sources in dairy rations, in transition period and early lactation on follicular dynamics, reproductive efficiency, nutrients intake and digestibility, composition and milk yield, composition of protein fraction and energy balance. Third Holstein cows, with production of 30,0 Kg/cow/day on previ

28. Dry matter production and distribution in three cassava (Manihot esculenta Crantz) cultivars during the second vegetative plant cycle
Com o objetivo de uma melhor compreensão da relação entre a produtividade total de massa seca e a proporção de alocação desta nas raízes tuberosas em plantas de mandioca, foi conduzido no município de Araruna-PR, um experimento em delineamento de blocos casualizados, em esquema de parcelas subdivididas com quatro repetições. Nas parcelas foram dis

29. Influência da arborização de pastagens no sistema solo-planta-animal. / Influence of tree planting in pastures on the soil-plant-animal system.
The purpose of this study was to evaluate influence of four leguminous trees species in the production, quality of the grass Brachiaria brizantha cv. Marandu, soil fauna, the microclimate, and the animal behavior in pastures cultivated in a consortium tree-grass system, comparing areas with scattered trees and a single grass pasture. The experiments were con

31. Ecophysiological attributes of hybrid DKB-390 and sthocastic model for predicting grain productivity / Atributos ecofisiológicos do híbrido DKB-390 e modelo estocástico para previsão da produtividade de grãos
Maize is on of the world most important crops, given that the products generated from this cereal are largely used by sectors like starch industry, animal and human nutrition, as well as biomass energy production and refineries. For these reasons, there is frequently a huge interest in knowing the potential adoption of the main available genotypes in relatio

32. Zn, Ni, Cu, Fe and S in sewage sludge: chemical behaviour, adsorption and treatment proposal / Zn, Ni, Cr, Cu, Fe e S em Iodo de esgoto: comportamento químico, adsorção e proposta de tratamento
The increase of the wastewater treated volume in Brazil has demanded alternatives to the sewage sludge final disposal. At first, agricultural use is one of the viable recommendations since sludge is rich in organic matter, macro and micronutrients necessary to the fertility of the soil. However, it is necessary to consider the environmental impact of some of

33. Macroinvertebrados bentônicos como indicadores de qualidade ambiental de afluentes do Rio Uberabinha, Uberlândia - MG / Benthic macroinvertebrates as environmental quality indicators of Uberabinha river tributaries, Uberlândia - MG
The use of biotic indices and different metrics of benthic macroinvertebrates has been widely used in studies on lotic systems in the context of environmental assessment, as well as the knowledge of the biotic and abiotic relationship and longitudinal dynamics of physico-chemical variables of these aquatic environments. This study aimed to evaluate the water

34. NITROGEN IN GRAPEVINE: RECOVERY, ACCUMULATION AND ALTERATIONS IN THE YIELD AND GRAPE COMPOSITION / NITROGÊNIO EM VIDEIRA: RECUPERAÇÃO, ACUMULAÇÃO E ALTERAÇÕES NA PRODUTIVIDADE E NA COMPOSIÇÃO DA UVA
The rate of nitrogen (N) in grapevines in the Rio Grande do Sul (RS) State, Southern Brazil, is established considering N content in leaves or leaves petioles and yield expectation limits. Once N fertilization needs have been diagnosed, the N is applied in indefinite times. However, N fertilization recommendations dont consider the impact of N fertilization

In tropical and subtropical areas, especially, where there is the dry period occurrence, the acidity subsurface (below the 10 cm) it has been pointed as one of the limitation causes to the growth of roots and the agricultural productivity. In the state of Rio Grande do Sul, in the last years, reports exist that areas under no tillage that don t present excha

36. Physical evaluation of a medium texture red latosol, as influenced by the application of swine manure and poultry bed / Avaliação física de um latossolo vermelho textura média, Influenciada pela aplicação de dejetos de suínos e cama aviária
Hog production and poultry raising constitute types of livestock activities which are of paramount social and economic importance for human nutrition in Brazil and also for generating wealth to the country economy through exports. The impressive increase in Brazilian exportation of swine and poultry has lead to intensive raising, that in turn has generated a
