Abstract

The aim of this study was to evaluate the effects of different soil management systems on the soybean yield components intercropped or not with Brachiaria decumbens, in the coastal plateau of the Alagoas State, Brazil. For that, the 9350 Monsoy soybean was cultivated under conventional tillage, minimum tillage, and no-tillage. The experiment was carried out by using a split-plot randomized blocks design (with and without B. decumbens) and four replications. The variables analyzed were: 1) soybean: determination of phenological stages, chemical composition of plants, stand of plants, stem diameter, plant height, first pod insertion height, number of grains per pod, number of pods, number of grains per plant, mass of 1,000 grains, and yield; and 2) B. decumbens: chemical composition of plants and accumulation of dry matter, in five different sampling times. The soil management systems influenced the stand of plants and the concentration of P, Cu, Fe, and Zn, in soybean, besides S, in B. decumbens. The no-tillage system showed higher grain and biomass yield for B. decumbens, under the edaphoclimatic conditions of Rio Largo, Alagoas State, Brazil.

KEY-WORDS: No-tillage; crop-livestock integrated system; minimum tillage.
