Resumo: The development of new technologies that aim at increasing the efficiency of nitrogen (N) fertilizers is essential for the agricultural sustainability. Thus, this study aimed at evaluating the cotton plants response to different topdressing N sources, under no-till system, in the Brazilian Savannah, in the 2008/2009 and 2009/2010 growing seasons. Treatments consisted of three N sources (urea, urea with urease inhibitor and ammonium nitrate) and two topdressing N fertilization applications (one application at V5 and two applications, as it follows: 50% at V5 + 50% at B6), plus a control (without topdressing N). The ammonium nitrate application provided the best results for both seasons, while the urea with urease inhibitor differed from urea only in the first season. The topdressing N fertilization provided different results among crops, being dependent of environmental conditions. If there is sufficient rainfall to incorporate the N to soil, better yields can be expected, when all the topdressing fertilization takes place at the V5 stage.

Assim, este trabalho objetivou avaliar a resposta do algodoeiro a diferentes fontes de nitrogênio (N) em cobertura, aplicadas em sistema plantio direto, no Cerrado, nos anos agrícolas 2008/2009 e 2009/2010. Os tratamentos constituíram-se de três fontes de N (ureia, ureia com inibidor de urease e nitrato de amônio) e dois manejos da adubação de N em cobertura (uma aplicação em V5 e duas aplicações, como se segue: 50% em V5 + 50% em B6), além de uma testemunha (sem N em cobertura). O nitrato de amônio promoveu melhor resultado, nos dois períodos avaliados, enquanto a ureia com inibidor de urease diferiu da ureia comum apenas no primeiro ano. O manejo do N em cobertura propiciou resultados diferentes entre os cultivos, sendo dependente das condições ambientais. Caso ocorra precipitação suficiente para incorporação do N ao solo, pode haver melhores produtividades, quando o adubo de cobertura for aplicado todo na fase V5.Escola de Agronomia - Universidade Federal de Goiás2013-04-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/19581Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 43, n. 1, Jan./Mar. 2013; 57-63Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 43, n. 1, jan./mar. 2013; 57-63Pesquisa Agropecuária Tropical; v. 43, n. 1, jan./mar. 2013; 57-631983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/19581/13862Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessKaneko, Flávio HiroshiLeal, Aguinaldo José FreitasAnselmo, Jefferson LuísBuzetti, SalatiérTosta, Fábio da Silva2020-07-10T12:01:27Zoai:ojs.revistas.ufg.br:article/19581Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:57.111591Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
