Resumo: The effect of five levels of nitrogen (0, 50, 100, 150 e 200 kg N/ha) on the dry matter production of "common" annual ryegrass (Lolium multiflorum Lam.) was studied during a two-year period. The experiment was carried out at field conditions in the UEPAE - Cinco Cruzes - EMBRAPA, Bage, Southwest of Rio Grande do Sul – Brazil. The soil under the experiment is mapped as a Planosolo Vértico. Urea was used as the nitrogen source. The treatments were arranged in randomized blocks design with four replications. Results showed that "common" annual ryegrass dry matter yields - increased with nitrogen application. However, dry matter yields were not proportionally increased when higher levels of nitrogen were applied. For the experimental conditions here defined, the level of 50 kg N/ha was the most efficient.

Realizou-se o trabalho sob condições de campo, na UEPAE "Cinco Cruzes" de Bagé, EMBRAPA, situada na região sudoeste do Estado do Rio Grande do Sul, em um Planosolo Vértico da unidade de mapeamento Bagé. O delineamento usado foi o de blocos completos ao acaso, com quatro repetições. Como fonte de nitrogênio usou-se a uréia. Os resultados mostraram que o azevém anual "comum" respondeu à aplicação de nitrogênio. O fato, contudo, não resultou em aumento quando se elevaram os níveis deste elemento. Para as condições de realização do trabalho, o nível de 50 kg N/ha foi o que se mostrou mais eficiente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGonçalves, José Otávio Neto2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16641Pesquisa Agropecuaria Brasileira; v.14, n.1, jan. 1979; 47-51Pesquisa Agropecuária Brasileira; v.14, n.1, jan. 1979; 47-511678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16641/10947info:eu-repo/semantics/openAccess2014-04-15T19:21:30Zoai:ojs.seer.sct.embrapa.br:article/16641Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:21:30Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
