Resumo
The common bean requires high levels of nitrogen to achieve high productivity. The cultivation under no tillage and the use of bacteria in seed inoculation contribute to the nitrogen contribution benefiting the grain yield. Aiming to evaluate the effects of different plant coverage and drying times of the agronomic performance of common bean inoculated with rhizobia were conducted two field experiments in winter crop in Santo Antônio de Goiás - GO and Ceres - GO . The experiments were implemented in design of randomized blocks with four replications, in a factorial design with sub split plot 5 x 4 x 2 + 4, five plants cover, four seasons of desiccation, two treatments of common bean seeds and four witnesses. The experiments were conducted in two stages. The first, with the implementation and management of cover crops, and the second, with seeding, management and harvesting of common bean. The variables analyzed in cover crops were fresh weight, dry weight and total-N. The common bean we evaluated the number of nodules, dry mass of nodules, fresh weight and shoot dry, root dry weight and yield components. The results showed that late planting of cover crops did not favor the covering soil. The plant cover and inoculation influenced the agronomic performance of common bean. The beans inoculated with rhizobia performed better. Cultivation in no-till on straw grass stood out regarding the use of legumes.
