Resumo: The objective of this work was to evaluate the effects of cover crops on the yield of upland rice (Oryza sativa) grown under no‑tillage system, in the presence and absence of N fertilizer, as well as to quantify, in the field, the use efficiency of N from urea and cover crops by upland rice, through the 15N isotope dilution technique. The field experiment was carried out in the municipality of Selvíria, in the state of Mato Grosso do Sul, Brazil, in an Oxisol (Rhodic Hapludox) in the Cerrado (Brazilian savanna) region. The experimental design was a randomized complete block with 15 treatments and four replicates, in a 5x3 factorial arrangement. The treatments were four cover crops (Crotalaria juncea, Cajanus cajan, Mucuna pruriens, and Pennisetum glaucum) + spontaneous vegetation (fallow in off-season), combined with three forms of N fertilization: control treatment, without N fertilizer application; 20 kg ha-1 N at sowing; and 20 kg ha-1 N at sowing plus 60 kg ha-1 N as topdressing. Rice is not affected by N fertilizer application as topdressing, when legume cover crops are used. The use of legume cover crops provides higher grain yield and use of fertilizer‑N by rice than that of millet or fallow. Legume cover crops promote an effect equivalent to that of the application of 60 kg ha-1 N as urea on rice yield.

O experimento de campo foi realizado em Selvíria, MS, em um Latossolo Vermelho distroférrico, na região do Cerrado. O delineamento experimental foi o de blocos ao acaso com 15 tratamentos e quatro repetições, em arranjo fatorial 5x3. Os tratamentos foram quatro espécies de plantas de cobertura (Crotalaria juncea, Cajanus cajan, Mucuna pruriens e Pennisetum glaucum) + vegetação espontânea (pousio), combinados com três formas de adubação nitrogenada: controle, sem aplicação de N; 20 kg ha-1 de N em semeadura; e 20 kg ha-1 de N em semeadura mais 60 kg ha-1 de N em cobertura. O arroz não responde à aplicação de N em cobertura, quando leguminosas são usadas como plantas de cobertura. O uso de leguminosas como planta de cobertura resulta em maior produtividade de grãos e aproveitamento do N do fertilizante pelo arroz do que o uso de milheto ou pousio. As leguminosas proporcionam efeito equivalente à aplicação de 60 kg ha-1 de N na forma de ureia sobre a produtividade de grãos de arroz.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFundação de Amparo à Pesquisa do Estado se São Paulo - FAPESPAg~encia Internacional de Energia Atômica - IAEAConselho Nacional de Desenvolvimento Científico e Tecnológico - CNPqFundação de Amparo à Pesquisa do Estado de São Paulo (Fapesp)International Atomic Energy Agency (IAEA)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Silva, Edson CabralMuraoka, TakashiFranzini, Vinícius IdeSakadevan, KaruppanBuzetti, SalatiérArf, OrivaldoBendassolli, José AlbertoSoares, Frederico Antonio Loureiro2016-08-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/23371Pesquisa Agropecuaria Brasileira; v.51, n.6, jun. 2016; 728-737Pesquisa Agropecuária Brasileira; v.51, n.6, jun. 2016; 728-7371678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/23371/13297https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/23371/15332Direitos autorais 2016 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2016-09-21T12:04:58Zoai:ojs.seer.sct.embrapa.br:article/23371Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2016-09-21T12:04:58Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
