Resumo: The aim of this study was to evaluate the nitrogen topdressing influence in common bean irrigated (winter-spring), in the first year of no tillage implementation. The experimental design was split-plot with three replications in randomized blocks. The plots were formed by three types of ground cover, corn-grain, corn-grain intercropped with Brachiaria ruziziensis and only B. ruziziensis. The subplots were formed by five doses of nitrogen topdressing (0, 40, 80, 120 and 160 kg ha-1), using urea as nitrogen source. It was determined the dry mass of residue present as ground cover, the full flowering time, the leaf nitrogen content, the 100 grains mass, the grain yield, the processing income, the chemical soil properties and economic analysis of common bean grain yield. It was found the common bean grain productivity in succession to corn-grain was positively influenced by nitrogen fertilization, showing it is economically viable only when given 160 kg ha-1 of nitrogen and the intercropping corn-grain and B. ruziziensis use is the best option when the common bean is sown in succession.

O delineamento experimental utilizado foi o de parcelas subdivididas, com três repetições, dispostos em blocos casualizados. As parcelas foram formadas por três formas de cobertura do solo, milho-grão, milhogrão consorciado com Brachiaria ruziziensis e apenas B. ruziziensis. As subparcelas foram formadas por cinco doses de adubação nitrogenada em cobertura (0, 40, 80, 120 e 160 kg ha-1), utilizando a uréia como fonte de nitrogênio. Foi determinada a massa seca da palhada presente como cobertura do solo anteriormente à semeadura da cultura do feijoeiro, o momento do florescimento pleno, o teor foliar de nitrogênio total, a massa de 100 grãos, a produtividade de grãos, a renda de beneficiamento, os atributos químicos do solo e a análise econômica da produção de grãos de feijão. Verificou-se que a produtividade de grãos de feijão em sucessão ao milho-grão foi influenciada positivamente pela adubação nitrogenada, sendo economicamente viável apenas quando fornecido 160 kg ha-1 de nitrogênio e que o uso do consórcio entre milho-grão e B. ruziziensis é a melhor opção quando o feijoeiro é semeado em sucessão.UEL2012-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Científicoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/893010.5433/1679-0359.2012v33n6Supl1p2825Semina: Ciências Agrárias; Vol. 33 No. 6Supl1 (2012); 2825-2836Semina: Ciências Agrárias; v. 33 n. 6Supl1 (2012); 2825-28361679-03591676-546Xreponame:Semina.
