Resumo: Bean genotypes react differently to available nitrogen. This research aimed at selecting bean genotypes, concerning their efficiency and reaction to nitrogen absorption. The treatments consisted of twelve genotypes cultivated in two different environments, one simulating a low nitrogen level (20 kg ha-1) and the other a high nitrogen level (120 kg ha-1). The experimental design was randomized complete bocks, with four replications. The grain yield was evaluated, for classifying cultivars in relation to nitrogen use efficiency and response to application, as well as chlorophyll rates, by using a chlorophyllometer. The BRS-Grafite and Princesa genotypes were considered efficient, regarding the nitrogen fertilization, and responsive to the nitrogen application. Bean plants supplied with adequate nitrogen rates presented higher cholorophyll (a, b and total) levels.

Assim, objetivou-se, com este trabalho, selecionar genótipos de feijoeiro, quanto à eficiência e resposta à absorção de nitrogênio. Os tratamentos envolveram doze genótipos cultivados em dois ambientes distintos, um simulando baixo nível (20 kg ha-1) e outro alto nível (120 kg ha-1) de nitrogênio. O delineamento experimental utilizado foi o de blocos completos casualizados, com quatro repetições. Foram avaliados a produtividade de grãos, para classificação das cultivares quanto à eficiência no uso e resposta à aplicação de nitrogênio, e índices de clorofila, com o uso de clorofilômetro. Os genótipos de feijão BRS-Grafite e Princesa foram eficientes, quanto à utilização da adubação nitrogenada, e responsivos à aplicação de nitrogênio. Plantas de feijoeiro conduzidas com adequado suprimento de nitrogênio apresentaram maiores índices de clorofila (a, b e total).Escola de Agronomia - Universidade Federal de Goiás2012-10-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/15413Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 42, n. 4, Oct./Dec. 2012; 368-374Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 42, n. 4, out./dez. 2012; 368-374Pesquisa Agropecuária Tropical; v. 42, n. 4, out./dez. 2012; 368-3741983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/15413/12062Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessSalgado, Fabricio Henrique MoreiraSilva, JoednaOliveira, Taynar Coelho deBarros, Hélio BandeiraPassos, Nathan Gonçalves dosFidelis, Rodrigo Ribeiro2020-07-10T11:46:00Zoai:ojs.revistas.ufg.br:article/15413Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:53.079031Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
