Resumo: The objective of this work was to assess the accumulation of dry matter and nutrients in forage plants intercropped with off-season maize, as a function of nitrogen fertilization. The species Urochloa brizantha cv. Marandu, U. decumbens cv. Basilisk, U. ruziziensis cv. Comum, and Panicum maximum cv. Tanzânia, with seeding in mid-March, were evaluated in four municipalities of São Paulo, Brazil, intercropped with maize. A randomized complete block design was used, with four replicates, in split-plots. The intercropped systems were evaluated in the plots, and four nitrogen topdressing fertilization rates (0, 30, 60, and 90 kg ha-1) were evaluated in the split-plots. Forage dry matter and nutrient accumulation were determined in three stages: flowering, maize physiological maturity, and at forage desiccation, in October. Forage dry matter accumulation increases after the harvest of off-season maize. When forages are planted in the corn inter-rows, topdressing nitrogen fertilization does not influence forage dry matter and nutrient accumulation, and intercropping does not affect off-season maize grain yield.

As espécies Urochloa brizantha cv. Marandu, U. decumbens cv. Basilisk, U. ruziziensis cv. Comum e Panicum maximum cv. Tanzânia, com semeadura em meados de março, foram avaliadas em quatro municípios paulistas, em consórcio com o milho. Utilizou-se o delineamento experimental de blocos ao acaso, com quatro repetições, em parcelas subdivididas. Nas parcelas, foram avaliados os consórcios e nas subparcelas, quatro doses de nitrogênio em cobertura (0, 30, 60 e 90 kg ha-1). Foi determinado o acúmulo de matéria seca e de nutrientes pelas plantas forrageiras em três épocas: no florescimento, na maturidade fisiológica do milho e por ocasião da dessecação das forrageiras, em outubro. O acúmulo de matéria seca das forrageiras intensifica-se após a colheita do milho safrinha. Quando as forrageiras são semeadas na entrelinha do milho, a adubação nitrogenada em cobertura não interfere no acúmulo de matéria seca e de nutrientes pelas forrageiras, e o consórcio não afeta a produtividade de grãos de milho safrinha.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPESPBatista, KarinaDuarte, Aildson PereiraCeccon, GessiDe Maria, Isabella CleiriceCantarella, Heitor2012-01-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/9066Pesquisa Agropecuaria Brasileira; v.46, n.10, out. 2011: Número Temático Sistemas de Integração Lavoura-Pecuária-Floresta; 1154-1160Pesquisa Agropecuária Brasileira; v.46, n.10, out. 2011: Número Temático Sistemas de Integração Lavoura-Pecuária-Floresta; 1154-11601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/9066/6624https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/9066/4440info:eu-repo/semantics/openAccess2014-06-13T17:39:29Zoai:ojs.seer.sct.embrapa.br:article/9066Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-06-13T17:39:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
