Resumo: The objective of this work was to evaluate the agronomic performance of the maize and xaraés palisade grass (Urochloa brizantha 'Xaraés') crops in intercropping, grown in no‑tillage and conventional tillage, in an agrosilvopastoral system, with the application of different nitrogen topdressing rates. The experiment was conducted in a maize crop area with the forest species “mulateiro” (Calycophyllum spruceanum). The experimental design was randomized complete blocks, in a split‑plot arrangement with two systems of soil management (no‑tillage and conventional tillage with heavy disk) allocated to the plots and five rates of nitrogen topdressing (0, 50, 100, 150, and 200 kg ha‑1 N) to the subplots, totaling ten treatments. Maize grain yield responded linearly to N application in area of ​​conventional tillage. In no‑tillage area, the dose of 165 kg ha‑1 N topdressing was necessary to obtain satisfactory yields. Nitrogen topdressing in maize crop until the dose of 200 kg ha‑1 N does not influence xaraés palisade grass yield when intercropped between the lines, after maize harvest.

O experimento foi conduzido em área de cultivo de milho com a espécie florestal mulateiro (Calycophyllum spruceanum). Utilizou-se o delineamento experimental de blocos ao acaso, com arranjo em parcelas subdivididas, com dois sistemas de manejo do solo (plantio direto e convencional com grade pesada) alocados nas parcelas e com cinco doses de adubação nitrogenada em cobertura (0, 50, 100, 150 e 200 kg ha‑1 de N), nas subparcelas, o que totalizou dez tratamentos. A produtividade de grãos de milho respondeu linearmente à aplicação de N em área de plantio convencional. Em área de plantio direto, a dose de 165 kg ha‑1 de N em cobertura foi necessária para a obtenção de produtividades satisfatórias. A adubação nitrogenada em cobertura na cultura do milho, até a dose de 200 kg ha‑1 de N, não influencia o rendimento do capim‑xaraés em consórcio nas entrelinhas, após a colheita do milho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBravin, Maísa PintoOliveira, Tadário Kamel de2014-11-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/19529Pesquisa Agropecuaria Brasileira; v.49, n.10, out. 2014; 762-770Pesquisa Agropecuária Brasileira; v.49, n.10, out. 2014; 762-7701678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/19529/12802https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/19529/11791info:eu-repo/semantics/openAccess2014-11-14T18:14:43Zoai:ojs.seer.sct.embrapa.br:article/19529Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-14T18:14:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
