Resumo: The economic analysis of the effect of applied nitrogen on a rye-grass (Lolium multiflorum Lam.) pasture was done, utilizing five levels of nitrogen on a field experiment. The data showed that the maximum technical efficiency was reached with the utilization of 154 kg/ha/year of N and the highest economical efficiency with 86 kg/ha/year of N. Since the price of N varies frequently the alternative that was found for maintaining the relation between fertilizer and product up-to-date, a table that shows the highest economical efficiency for any price of nitrogen/product relationship was built. This means that, for any variation in the relation of prices fertilizer/product one is able to find a new optimum level of nitrogen.

Utilizou-se a curva de resposta de um experimento de campo, onde a gramínea foi submetida a cinco níveis de nitrogênio. Os resultados mostraram que a máxima eficiência técnica foi atingida com 154 kg/ha/ano de N; e a máxima eficiência econômica, com 86 kg/ha/ano de N. Para compensar a instabilidade da moeda, construiu-se uma tabela que relaciona a variação de preço insumo/produto com os respectivos níveis de máxima eficiência econômica no uso do fator, ou seja, para qualquer alteração na relação de preços, calculou-se uma nova dose ótima econômica.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSalles, Pedro Afonso Almeida deGonçalves, José Otávio Neto2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16464Pesquisa Agropecuaria Brasileira; v.16, n.1, jan. 1981; 27-31Pesquisa Agropecuária Brasileira; v.16, n.1, jan. 1981; 27-311678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16464/10733info:eu-repo/semantics/openAccess2014-04-15T19:35:55Zoai:ojs.seer.sct.embrapa.br:article/16464Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:35:55Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
