Resumo: Nitrogen fertilization is an important management practice in grasses and quite complex, due to several factors which influence it, such as climatic conditions, cropping systems and available levels and sources. This study aimed at evaluating the effect of topdressing nitrogen (N) sources and levels on the productive characteristics of wheat (Triticum aestivum L.) grown after soybean, under no-till system. The experiment was conducted in an Oxisol, in Londrina, Paraná State, Brazil. The experimental design was randomized blocks, in a 3x4 factorial scheme, with four replications. As topdressing N sources, urea, urea + urease inhibitor (NBPT) and polymer-coated urea were evaluated, in 2008, and urea, urea + urease inhibitor (NBPT) and ammonium sulfate, in 2009, in four doses (0.0 kg ha-1, 40.0 kg ha-1, 80.0 kg ha-1 and 120.0 kg ha-1 of N) applied 20 days after emergence. Plant height, lodging percentage, mass of 1,000 grains, grain yield and hectoliter mass were determined, and results showed that increased topdressing N levels promoted plants lodging, decreasing the mass of 1,000 grains, yield and hectoliter mass. The N sources did not affect the yield of the BRS Pardela cultivar grown after soybean.

Este trabalho objetivou avaliar o efeito de fontes e doses de nitrogênio (N) em cobertura sobre as características produtivas do trigo (Triticum aestivum L.) cultivado em sistema de semeadura direta, em sucessão à cultura da soja. O experimento foi realizado utilizando-se Latossolo Vermelho distroférrico, em Londrina (PR). O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial 3x4, com quatro repetições. Como fontes de N na adubação de cobertura, foram avaliados a ureia, ureia + inibidor de urease (NBPT) e ureia revestida com polímeros, em 2008, e ureia, ureia + inibidor de urease (NBPT) e sulfato de amônio, em 2009, em quatro doses (0,0 kg ha-1, 40,0 kg ha-1, 80,0 kg ha-1 e 120,0 kg ha-1 de N) aplicadas 20 dias após a emergência das plantas. Foram avaliados a altura de plantas, percentagem de acamamento, massa de 1.000 grãos, rendimento de grãos e massa do hectolitro, e os resultados mostraram que o incremento nas doses de N em cobertura favoreceu o acamamento de plantas, proporcionando redução na massa de 1.000 grãos, na produtividade e na massa do hectolitro. As fontes de N não afetaram o desempenho produtivo da cultivar BRS Pardela, cultivada após a soja.Escola de Agronomia - Universidade Federal de Goiás2013-04-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/20247Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 43, n. 1, Jan./Mar. 2013; 34-41Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 43, n. 1, jan./mar. 2013; 34-41Pesquisa Agropecuária Tropical; v. 43, n. 1, jan./mar. 2013; 34-411983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/20247/13795Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessPrando, Andre MateusZucareli, ClaudemirFronza, VanoliOliveira, Fábio Álvares deOliveira Júnior, Adilson2020-07-10T12:07:26Zoai:ojs.revistas.ufg.br:article/20247Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:57.772586Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
