Produtividade da soja em função de diferentes sistemas de preparos do solo e adubos verdes

Abstract

Green manuring allied to soil preparation systems are practices that aim to preserve the quality of the environment without affecting the high productivity of crops and economic return. The experiment was conducted at the experimental station of the Federal University of Mato Grosso do Sul, Chapadão do Sul campus. The experimental design was in randomized blocks in subdivided plots, where the plots were composed of three different soil managements: conventional tillage (CC), minimum tillage (CM) and no-till farming (PD). The subplots consisted of four ground covers: fallow, millet, turnip and millet+turnip. The following parameters were evaluated: plant height (PA), first pod insertion (PIV), number of nodes (NN), productive branches (RP) and number of grains (NG). It was found that soybean obtained better agronomic characteristics in the no-till crop under millet+node ground cover.
