dc.description.abstractThe vegetal residues maintenance on soil surface, characteristic of no-tillage system have changing the nutrients availability. So, in this sense, the aim of this work was to evaluate the effect of times of N application on corn sowed in no tillage system under vegetable residues of different species used for soil covering and straw supply in the cerrado area. The experiment was carried out in field conditions, in an Oxisol characteristic of this area. The treatments were constituted by the combination of different times of N application: (43+23+20+00); (00+70+20+00); (00+00+90+00); (00+00+20+70); (00+00+00+90) with an control treatment (absence of nitrogen), in kg ha(-1), respectively 30 days before the desiccation, at desiccation, at sowing and at sidedress of corn, sowed directly on Penisetum americanum and Brachiaria decumbens residues. By the results it can be concluded that nitrogen application in soybean, independent of time, does not increase productivity in relation to the treatment without nitrogen application.en
dc.description.abstractA manutencao da palha na superficie do solo no sistema plantio direto tem levado a uma modificacao na disponibilidade de nutrientes. Nesse sentido, o presente trabalho objetivou avaliar o efeito de epocas de aplicaca de nitrogenio na soja em plantio direto sob palha de duas especies utilizadas para a cobertura do solo na regiao de cerrado. O experimento foi desenvolvido em um Latossolo Vermelho Distrofico, caracteristico desta regiao. Os tratamentos foram constituidos pela combinacao de epocas de aplicacao de N: (43+23+20+00); (00+70+20+00); (00+00+90+00); (00+00+20+70); (00+00+00+90) e um tratamento testemunha, em kg ha-1, respectivamente 30 dias antes da dessecacao, na dessecacao, na semeadura e em cobertura, na cultura da soja, semeadas diretamente sobre os residuos de milheto ou braquiaria. A adubacao nitrogenada na cultura da soja, independente da epoca de aplicacao, nao proporciona aumento de produtividade em relacao ao tratamento sem aplicacao de nitrogenio.pt
