Resumo: Appropriate use of N fertilizer for irrigated corn increases the yield and the economic return, and it also reduces the risk of water pollution. The objective of this study was to determine corn response to nitrogen. The field experiment was carried out on a clayey typic Haplustox, using a complete split-plot randomized block design with four replications. Nitrogen rates (0, 60, 120, 180 and 240 kg ha-1 N as urea, in dress application split through the season) were the main plots and the rotation cropping systems, corn-corn-corn and corn-soybean-corn, were the split-plots. Nitrogen fertilization increases the corn yield in 28% in relation to control. Greatest grain yield, 11,203 kg ha-1, was obtained with the highest N rate (240 kg ha-1). There was no effect of cropping system in grain yield, but N content in shoot dry matter and in corn grains were larger in corn-soybean-corn system.

O objetivo deste trabalho foi determinar a resposta do milho à aplicação de nitrogênio. O experimento foi realizado em Latossolo Vermelho distroférrico típico, de textura argilosa. O delineamento experimental foi em blocos casualizados com parcelas subdivididas e quatro repetições, tendo como tratamento nas parcelas as doses de N em cobertura (0, 60, 120, 180 e 240 kg ha-1), utilizando a uréia e, nas subparcelas, as seqüências de culturas milho-milho-milho e milho-soja-milho. A adubação nitrogenada proporcionou, em relação à testemunha, aumento de 28% (2.448 kg ha-1) na produção de grãos de milho. A maior produtividade de grãos, 11.203 kg ha-1, foi alcançada com a maior dose de N (240 kg ha-1). O sistema de rotação não teve efeito na produtividade, mas os teores de N na massa de matéria seca da parte aérea da planta e nos grãos de milho foram maiores no sistema milho-soja-milho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAraújo, Luiz Alberto Navarro deFerreira, Manoel EvaristoCruz, Mara Cristina Pessôa da2004-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6837Pesquisa Agropecuaria Brasileira; v.39, n.8, ago. 2004; 771-777Pesquisa Agropecuária Brasileira; v.39, n.8, ago. 2004; 771-7771678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6837/3893info:eu-repo/semantics/openAccess2014-08-21T19:34:37Zoai:ojs.seer.sct.embrapa.br:article/6837Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-21T19:34:37Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
