Resumo: | The nitrogen is the nutrient required in greatest quantities by the bean crop and the response to its application depends on the applied N rate as well as the time of its application. The objective of this work was to evaluate yield components, grain productivity and physiological quality of bean seeds, affected by different nitrogen (urea) rates top-dressed at three crop growth stages. The experiment was conducted in no-till system. The treatments were constituted by 0, 40, 80, 120, 160, 200 and 240 kg ha-1 N top-dressed at V4-5, R5 and R6 growth stages, corresponding to 21, 32 and 38 days after plant emergence, respectively. Seed physiological quality was evaluated by germination and vigor tests. Nitrogen applied at different crop growth stages did not interfere on the yield components, but interfered on bean productivity. Maximum grain productivity was obtained with top-dressed 164 kg ha-1 N, independently of growth stage application. Seed physiological quality was not affected by the treatments, fitting in the category of seeds for commercialization. |

A resposta à sua aplicação depende da dose aplicada e da época de sua aplicação. O objetivo deste trabalho foi avaliar os componentes de produção, produtividade de grãos e a qualidade fisiológica de sementes de feijão, decorrentes de diferentes doses de N (uréia) aplicadas em cobertura em três estádios da cultura. O experimento foi conduzido no sistema plantio direto. Os tratamentos foram constituídos por 0, 40, 80, 120,160, 200 e 240 kg ha-1 de N aplicados em cobertura nos estádios V4-5, R5 e R6, correspondendo, respectivamente, a 21, 32 e 38 dias após a emergência das plantas. A qualidade fisiológica de sementes foi avaliada por meio do teste de germinação e testes de vigor. O N aplicado nas diferentes fases da cultura não interferiu nos componentes de produção. A máxima produtividade de grãos foi obtida com 164 kg ha-1 de N em cobertura, independentemente do estádio de desenvolvimento. A qualidade fisiológica das sementes não foi influenciada pelos tratamentos.Universidade Estadual Paulista Júlio de Mesquita Filho Fac. de Engenharia, Caixa Postal 31, CEP 15385-000 Ilha Solteira, SPUniversidade Estadual Paulista Júlio de Mesquita Filho Fac. de Engenharia, Caixa Postal 31, CEP 15385-000 Ilha Solteira, SPUniversidade Estadual Paulista (Unesp)De Andrade Meira, Flávia [UNESP]De Sá, Marco Eustáquio [UNESP]Buzetti, Salatiér [UNESP]Arf, Orivaldo [UNESP]2014-05-27T11:21:18Z2014-05-27T11:21:18Z2005-04-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article383-388application/pdfhttp://dx.doi.org/10.1590/S0100-204X2005000400010Pesquisa Agropecuaria Brasileira, v. 40, n. 4, p. 383-388, 2005.0100-204Xhttp://hdl.handle.net/11449/6817610.1590/S0100-204X2005000400010S0100-204X2005000400010WOS:0002296136000102-s2.0-217444524702-s2.0-21744452470.pdf075650411327366265133398947814522359995407903863Scopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPporPesquisa Agropecuária Brasileira0.546info:eu-repo/semantics/openAccess2023-11-25T06:16:13Zoai:repositorio.unesp.br:11449/68176Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462023-11-25T06:16:13Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false |
