Resumo: | Green manure is still a not widely used practice in wheat crop, although economic benefits and conservation of natural resources can be observed due to the adoption of this practice. This study was carried out at the Dourados, Mato Grosso do Sul State, Brazil, with the objective of evaluating the effect of sunn hemp (Crotalaria juncea) and hairy vetch (Vicia villosa), associated with levels of mineral nitrogen topdressing in the agronomic performace of wheat crop under no-tillage. The treatments were constituted by green manures, fallow as a treatment-control and six doses of mineral nitrogen topdressing: zero, 30, 60, 90, 120 and 150 kg ha-1. Urea was used as nitrogen source. Evaluations of dry mass of cover crops, nitrogen contents in green manures shoot and in wheat leaves, plant height, number of productive tillers per plant, one thousand-grains weight, hectolitric weight and yield were made. It was concluded that the use of green manures before wheat seeding promotes significant increases in crop yield, mainly when planted over to sunn hemp. The wheat yield response to mineral nitrogen application varied according to the preceding crop. |

Este estudo foi realizado em Dourados-MS, Brasil, com o objetivo de avaliar o efeito do cultivo de crotalária (Crotalaria juncea) e ervilhaca peluda (Vicia villosa) como adubos verdes, associados a doses de nitrogênio mineral em cobertura, no desempenho agronômico do trigo em sistema plantio direto. Os tratamentos foram constituídos pelos adubos verdes, um tratamento-testemunha em pousio e seis doses de nitrogênio mineral em adubação de cobertura do trigo: zero, 30, 60, 90, 120 e 150 kg ha-1, utilizando-se a ureia como fonte de nitrogênio. Foram realizadas avaliações de massa seca das coberturas vegetais, teores de nitrogênio na parte aérea dos adubos verdes e nas folhas de trigo, altura de plantas, número de perfilhos produtivos, massa de mil grãos, peso hectolitro e produtividade. Verificou-se que o cultivo de adubos verdes antecedendo a semeadura do trigo promove acréscimos significativos na produtividade da cultura, especialmente quando cultivado em sucessão à crotalária. A resposta do trigo à aplicação de nitrogênio mineral variou em função da cultura antecessora.UEL2011-10-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/511110.5433/1679-0359.2011v32n4p1375Semina: Ciências Agrárias; Vol. 32 No. 4 (2011); 1375-1384Semina: Ciências Agrárias; v. 32 n. 4 (2011); 1375-13841679-03591676-546Xreponame:Semina.
