Resumo: The objectives of this work were to evaluate biomass production and persistence and the desiccation efficiency in plant species used as cover crops, and to quantify its effects on cotton yield in a no-tillage system. The study was carried out in Santa Helena de Goiás, GO, Brazil, using 16 plant species: Panicum maximum, cultivars Mombaça, Tanzânia and Massai; Urochloa brizantha, cultivars Piatã, Xaraés, Marandu and MG4; U. decumbens; Paspalum atratum cv. Pojuca; Sorghum bicolor cultivars Santa Eliza and BRS 700; Pennisetum glaucum cv. ADR 500; Raphanus sativus; Eleusine coracana, Crotalaria spectabilis, and fallow plants as control. The species were sown early in March-2007. The lower dry biomass productivity and persistence were obtained with C. spectabilis, E. coracana, and R. sativus. Cotton seed and lint yield were higher when it was cultivated after the cultivars Tanzânia and Mombaça of P. maximum, in comparison to the ones observed using P. atratum cv. Pojuca, R. sativus, and fallow plants. Generally, S. bicolor, P. glaucum and the cultivars Tanzânia and Mombaça of P. maximum, and MG4, Piatã and Xaraés of U. brizantha have biomass persistence and productivity suitable for cotton cultivation in no-tillage systems in the Brazilian savannah.

O objetivo deste trabalho foi avaliar a produção, a persistência da matéria seca e a eficiência da dessecação em espécies vegetais utilizadas para cultivos de cobertura do solo, e quantificar seus efeitos sobre a produtividade do algodoeiro em plantio direto. O trabalho foi realizado em Santa Helena de Goiás, GO, com 16 tratamentos: Panicum maximum, cultivares Mombaça, Tanzânia e Massai; Urochloa brizantha, cultivares Piatã, Xaraés, Marandu e MG4; U. decumbens; Paspalum atratum cv. Pojuca; Sorghum bicolor cultivares Santa Eliza e BRS 700; Pennisetum glaucum cv. ADR 500; Raphanus sativus; Eleusine coracana, Crotalaria spectabilis, além da testemunha em pousio. As espécies foram semeadas no início de março (2007). As espécies com menores produtividades e persistência da matéria seca foram C. spectabilis, E. coracana e R. sativus. As produtividades de algodão em caroço e fibra foram maiores no cultivo sobre palhas residuais das cultivares Tanzânia e Mombaça de P. maximum, em comparação às observadas com uso de P. atratum cv. Pojuca, R. sativus e pousio. Em geral, S. bicolor, P. glaucum e as cultivares Tanzânia e Mombaça de P. maximum, e MG4, Piatã e Xaraés de U. brizantha apresentam produção e persistência da matéria seca adequadas para o cultivo do algodoeiro no sistema de plantio direto, no cerrado brasileiro.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFIALGO E EMBRAPAFerreira, Alexandre Cunha de BarcellosLamas, Fernando MendesCarvalho, Maria da Conceição SantanaSalton, Júlio CésarSuassuna, Nelson Dias2011-01-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7947Pesquisa Agropecuaria Brasileira; v.45, n.6, jun. 2010; 546-553Pesquisa Agropecuária Brasileira; v.45, n.6, jun. 2010; 546-5531678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7947/6035https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/7947/3585info:eu-repo/semantics/openAccess2014-10-17T18:45:52Zoai:ojs.seer.sct.embrapa.br:article/7947Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-17T18:45:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
