Resumo: The objective of this work was to evaluate cover crops shoot dry matter production and nutrients accumulation and the effect of straw mulch mechanical management on the dry season peanut crop nutrition and yield, in no-tillage system. The experiment was carried out on a dystroferric Hapludox, in Botucatu, SP, Brazil. A randomized blocks design, in a splitplot array, with four replications, was used. The plots were composed by cover crops: palisadegrass – Brachiaria brizantha cv. Marandu; pearl millet – Pennisetum glaucum cv. BN 2; and guineagrass – Panicum maximum cv. Mombaça. The subplots were composed by absence or presence of straw mulch mechanical management, by horizontal crusher use, 20 days after chemical management. Pearl millet presented the largest shoot dry matter production and the lowest nutrient contents, 71 days after emergence, in comparison with palisadegrass and guineagrass. The cover crops presented similar nutrients accumulation in shoot. The cover crops species and straw mulch mechanical management does not affect the peanut leaves nutrient contents and yield in no-tillage system.

O experimento foi instalado em um Latossolo Vermelho distroférrico, em Botucatu, SP. O delineamento utilizado foi o de blocos ao acaso, em parcelas subdivididas, com quatro repetições. As parcelas foram constituídas por três espécies de plantas de cobertura: braquiária – Brachiaria brizantha, cultivar Marandu; milheto – Pennisetum glaucum, cultivar BN 2; e panicum – Panicum maximum, cultivar Mombaça. As subparcelas foram constituídas pela ausência e presença do manejo mecânico da palhada, 20 dias após o manejo químico, mediante o uso de triturador de palha horizontal. O milheto apresentou a maior produção de matéria seca e o menor teor de nutrientes na parte aérea, aos 71 dias após a emergência, em comparação com a braquiária e o panicum. As quantidades de nutrientes acumuladas na parte aérea das plantas de cobertura foram semelhantes. A espécie de planta de cobertura do solo e o manejo mecânico da palhada não influenciam a nutrição e a produtividade do amendoim no sistema plantio direto.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCrusciol, Carlos Alexandre CostaSoratto, Rogério Peres2007-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7732Pesquisa Agropecuaria Brasileira; v.42, n.11, nov. 2007; 1553-1560Pesquisa Agropecuária Brasileira; v.42, n.11, nov. 2007; 1553-15601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7732/4651info:eu-repo/semantics/openAccess2014-10-13T19:28:08Zoai:ojs.seer.sct.embrapa.br:article/7732Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-13T19:28:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
