Resumo: The influence of nitrogen fertilization on the incidenceof brown spot (Helminthosporium oryzae Breda de Hann) on leavesof rice cultivar IAC 47 was studied under upland conditions. Theexperimental area was fertilized with 60 kg/ha P2O5, 30 kg/haK2O and 0, 15, 30, 45 and 60 kg/ha of N, in the form of ammoniumsulfate. Increase in nitrogen levels from 0 to 45 kg/ha decreased thenumber of lesions per leaf. A further increase to 60 kg/hA of Nincreased the lesion number.

Foram usados 60 kg/ha de P2O5, 30 kg/ha de K2O e zero, 15, 30, 45 e 60 kg/ha de N, na forma de sulfato de amônio. O aumento dos níveis de N, de zero a 45 kg/ha diminuiu o número de lesões por folha. O aumento de N para 60 kg/ha resultou em tendência de aumento do número de lesões.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFaria, Josias Correa dePrabhu, Anne Sitarama2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15503Pesquisa Agropecuaria Brasileira; v.18, n.12, dez. 1983; 1377-1379Pesquisa Agropecuária Brasileira; v.18, n.12, dez. 1983; 1377-13791678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15503/9460info:eu-repo/semantics/openAccess2014-04-16T18:50:16Zoai:ojs.seer.sct.embrapa.br:article/15503Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:50:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
