| Abstract: The objective of this work was to evaluate the effect of phytomass accumulation, soil cover, and nutrient cycling promoted by cultivation systems with annual and cover crops on the grain yield of soybean sown in succession in the Cerrado, in the state of Mato Grosso, Brazil. The experiment was carried out in a randomized complete block design with nine cultivation systems and four replicates, in two crop seasons. In 2014/2015, forage grasses and legumes were evaluated, besides fallow treatments. In 2015/2016, forage and legume intercropped or not with corn or sunflower and fallow were assessed; the soybean crop was evaluated following cover crops. Phytomass, soil cover, and nutrient cycling provided by cultivation systems, as well as soybean mass... |
