Resumo: The objective of this experiment was to evaluate the effects of mechanical and chemical management of oat straw and of sowing dates of maize after oat desiccation on maize grain yield and on alexandergrass (Brachiaria plantaginea Link) infestation. In 1997/98, treatments were composed by two mechanical management systems of oat (rolled or not) and bare area as the control, by two herbicides (glyphosate and paraquat) applied to desiccate oat straw and by two maize sowing dates after desiccation (one and 15 days). In the 1998/99 growing season, five management systems of oat straw (rolled, cleared and desiccated with glyphosate, glufosinate and paraquat) and a bare area used as check were tested. Delay of maize sowing date in 15 days after oat straw desiccation increased N accumulation, dry matter production per plant and grain yield of maize. Maize grain yield in succession to oat was not influenced by management system of oat straw. Rolling oat straw provided the best control of alexandergrass infestation.

No ano agrícola de (1997/98, os tratamentos constaram de dois sistemas de manejo mecânico da aveia-preta (rolada e não- rolada) e do pousio invernal (controle), da dissecação da palha de aveia-preta com dois herbicidas não-seletivos (glyphosate e paraquat) e de duas épocas de semeadura do milho após a dessecação da aveia-preta (um e 15 dias). Na estação de crescimento 1998/99, foram avaliados cinco sistemas de manejo da aveia-preta (rolada, roçada e dessecada com glyphosate, com glufosinate e com paraquat), e pousio invernal, como controle. O atraso de 15 dias na semeadura do milho após dessecação da aveia-preta aumentou o acúmulo de N, a produção de massa seca e o rendimento de grãos de milho. O rendimento de grãos de milho cultivado em sucessão à aveia-preta não foi influenciado pela forma de manejo mecânico ou pelo herbicida utilizado na dessecação da aveia-preta. A rolagem da aveia-preta foi mais eficiente em prevenir o estabelecimento de infestação de capim-papuã do que sua manutenção em pé.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraArgenta, GilberSilva, Paulo Regis Ferreira daFleck, Nilson GilbertoBortolini, Clayton GianiNeves, RodrigoAgostinetto, Dirceu2001-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6204Pesquisa Agropecuaria Brasileira; v.36, n.6, jun. 2001; 851-860Pesquisa Agropecuária Brasileira; v.36, n.6, jun. 2001; 851-8601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6204/3269info:eu-repo/semantics/openAccess2010-08-09T13:31:14Zoai:ojs.seer.sct.embrapa.br:article/6204Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-09T13:31:14Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
