Resumen
The bean plant, for being a protein-rich grains leguminous, have a lot of demand for nitrogen; demanding a continuous supply of this nutrient for its vegetative and reproductive development. If the availability of nitrogen happens only at the seeding moment, the tillage culd be not present good production, been the nitrogen a limiting factor. Cause of its short cycle, the nitrogen’s biologic fixation is not efficient, becoming required, for high production pourposes, the cover fertilization. The experiment was realized at Coronel Vivida/PR. The aim of this study was to evaluate the bean plant accomplishment in consequence of cover nitrogen application in different sources and doses. As base fertilization, was provided 32 kg ha-1 of nitrogen. In cover was applied doses until complete 40, 60 and 80 kg ha-1 of nitrogen, besides the control, using amidic nitrogen, ammonium nitrate and calcium nitrate sources. After data tabulation, these datas was submited a analysis of variance and was tested by F test, with 5% probability. When verified interaction, was accomplished the analysis of regression of quantitative factors and comparison of means, and, for qualitative factors, was accomplished the Tukey test, with 5% probability. The statistical program used was Genes. The nitrogen sources was not interfere in the results of Yield and productivity of common bean. The number of seeds per plant and the number of grain yield and yield components by plant was bigger with larger doses of nitrogen in cover application, however, this yield components increase the productivity.
