RESUMOO trabalho propôs verificar o efeito da aplicação de diferentes níveis de P em semeadura no feijoeiro cultivado sob diferentes plantas de cobertura. A pesquisa foi conduzida no período de inverno de 2010 e 2011, no Município de Selvíria, MS. O delineamento experimental foi o de blocos casualizados, em esquema de parcelas subdivididas com 4 repetições. As parcelas foram constituídas por: milheto, crotalária, guandu, mucuna-preta, milheto + guandu, milheto + crotalária e milheto + mucuna e pousio. As subparcelas foram constituídas por ausência de adubação fosfatada e doses de P 2 O 5 (60, 90 e 120 kg ha -1 ) na forma de monoamônio fosfato (MAP). Avaliaram-se: massa seca e acúmulo de P nas plantas de cobertura, componentes produtivos, P total na parte aérea e produtividade do feijoeiro. Concluiu-se que a Crotalária, os consórcios milheto + mucuna-preta e milheto + Crotalaria, produziram quantidade suficiente de matéria seca para viabilizar o sistema de plantio direto de feijão, o uso de palhada de Crotalaria juncea, milheto + Crotalaria juncea e milheto + mucuna-preta como plantas de cobertura antecessora proporcionou melhor desenvolvimento e produção do feijoeiro de inverno com economia na aplicação de P em sistema plantio direto.Palavras-chave: adubação de semeadura, fósforo, gramíneas, leguminosas, Phaseolus vulgaris L. Phosphate fertilizer plant coverages and on the bean "winter" in no-tillage system ABSTRACTThe survey was conducted during the winter of 2010 and 2011 in Selvíria, Mato Grosso do Sul State, Brazil. The experimental design was a randomized block in a split plot with four replications. The plots consisted of: millet, sun hemp, pea, velvet bean, millet + pigeon pea, millet and millet + Crotalaria and Mucuna fallow. The subplots were represented by the absence of phosphate fertilizers and doses of P 2 O 5 (60, 90 and 120 kg ha -1 ) in the form of monoammonium phosphate (MAP). Were evaluated: plant cover, dry matter of plants, components production, total P in shoots and productivity. It was concluded that Crotalaria juncea, the consortium millet + black velvet bean (Mucuna aterrima) and millet + Crotalaria juncea, produced sufficient amount of dry matter to make possible the no-tillage system and the use of straw Crotalaria juncea, millet + Crotalaria juncea and millet + velvet bean as cover crops provided better development and production of bean winter saving the application of phosphorus in no-tillage system.
