Qualidade de grãos de soja produzidos em sistemas integrados

Abstract

To meet the market requirements for a sustainable product and quality one of the alternatives studied is the Integrated production system, that seeks to reduce the impact caused by culture to the environment. The objective of this work to analyze the quality of soya beans produced in an integrated system consisting of soybean crop and eucalyptus. The integrated system was deployed with three eucalyptus tree 30 m apart from each other, being a primary row, and two lateral oriented towards north and south. Each row contained three rows of eucalyptus distanced of 3 m between rows. The distance between lines was used for cultivation of soy. To check the effect of forestry component on quality of soya beans, samples were harvested 4.5; 7.5 and 15.0 m of the eucalyptus tree. The quality of the grains was evaluated by means of its physical properties: water content, apparent density, thousand grain mass, color, chemical makeup and electrical conductivity. It is concluded, in general, that the shading from the eucalyptus tree promoted a qualitative improvement in the soya beans analyzed, so that, the closer of the eucalyptus tree, the greater the apparent density values, thousand grain mass and the lower the electrical conductivity values of exudates of soybean. Shading also caused a positive effect on the content of protein, lipids and carbohydrates
