Cover plants, succession of different crops and conservation management of soil aim the environmental preservation and system of crop grain production support. The objective of this work was to evaluate the influence of cover plants, previous crop and soil management on nutrient uptake, agronomical characteristics and grain yield of common bean cultivated during fall-winter. The experiment was carried out in a Typic Hapludox soil. The experimental design used was that of randomized blocks, in a split-split plot scheme, with four replications. Four cover plant and fallow (October-December) were been used in plots. In subplots, two soil management systems were used: no-tillage in implantation phase and conventional tillage (one disk harrow + two levelling harrow). In subsubplots, were growth three previous crops before bean (December to May). The cover plants had influence nutrients uptake but have not affected the agronomical characteristics and grain yield. The common bean grain yield was larger in succession soybean crop than in succession cotton or mayze crops.
Phaseolus vulgaris; crop rotation; no-tillage
