Resumo: Nitrogen supply and plant population are basic parameters for cereal-legume intercropping. In order to study plant population and nitrogen fertilizer effects on yield and yield efficiency of maize-bean intercropping, a field experiment was established. Three bean plant populations and three nitrogen levels were used. Maize dry matter accumulation decreased with increases in bean plant population. Competitive effect of intercrop beans on maize yields was high at higher plant populations, being decreased by nitrogen fertilizer; application of 50 kg ha-1 N was very efficient in increasing maize cob yield. Intercropping significantly decreased harvest index of beans in all plant population and nitrogen fertilizer situations. The efficiency of intercropping, compared to sole cropping, was evidenced by the values obtained for Land Equivalent Ratio (LER) for biomass, cob and pod yields that increased with increases in bean plant populations and nitrogen fertilizer levels.

Os efeitos de diferentes populações de plantas de feijão e níveis de nitrogênio na produção e eficiência do consórcio milho-feijão foram estudados em um experimento de campo. Foram usadas três populações de plantas de feijão e três níveis de nitrogênio. O acúmulo de matéria seca do milho durante o ciclo vegetativo decresceu à proporção que a população de feijão aumentou. O efeito competitivo do feijão na produção do milho consorciado, que se mostrou maior nas maiores populações de plantas, foi atenuado pela aplicação da adubação nitrogenada; a aplicação de 50 kg ha-1 de N foi muito eficiente no aumento da produção de espiga do milho. O consórcio diminuiu significativamente o índice de colheita do feijão em todas as populações de plantas e em todos os níveis de nitrogênio aplicados. A eficiência do consórcio, em comparação ao plantio isolado das culturas, foi comprovada por meio dos valores do índice Uso Eficiente da Terra (UET) correspondentes às produções de espiga, vagem e biomassa, que aumentaram com os incrementos tanto da população de plantas de feijão como dos níveis de nitrogênio.–Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMorgado, Luiz BalbinoWilley, Robert Williams2003-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6698Pesquisa Agropecuaria Brasileira; v.38, n.11, nov. 2003; 1257-1264Pesquisa Agropecuária Brasileira; v.38, n.11, nov. 2003; 1257-12641678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/6698/3755info:eu-repo/semantics/openAccess2014-08-11T19:41:11Zoai:ojs.seer.sct.embrapa.br:article/6698Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:41:11Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
