Resumo: | From 1984 to 1993, in Guarapuava, Paraná, Brazil, the effect of crop rotation systems on wheat were assessed. Four rotation systems for wheat were studied: system I (wheat/soybean); system II (wheat/soybean and common vetch/corn, from 1984 to 1989, and wheat/soybean and white oats/soybean, from 1990 to 1993); system III (wheat/soybean, flax/soybean, and common vetch/corn, from 1984 to 1989, and wheat/soybean, common vetch/corn, and white oats/soybean, from 1990 to 1993); and system IV (wheat/soybean, legume/corn, barley/soybean, and white oats/soybean). The economic analysis on that period is presented in this paper. From 1984 to 1989, systems I, II, III, and IV showed no differences in their net return means. Similarly, from 1990 to 1993, systems II, III, and IV mean net returns did not differ significantly in relation to the system I; however, considering the annual comparison, the system II showed higher profit than the system I in six years and did not differ in four years, making it a good alternative, mainly in the first period. |

A análise econômica do período é apresentada neste trabalho. De 1984 a 1989, os sistemas I, II, III e IV não mostraram diferenças entre as médias quanto à receita líquida. Da mesma forma, de 1990 a 1993, os sistemas II, III e IV não diferiram significativamente no tocante a receita líquida, em relação ao sistema I; no entanto, considerando-se as comparações anuais, o sistema II apresentou maior lucratividade do que o sistema I, em seis anos, e não diferiu em quatro anos, sendo, portanto, aquele, uma boa alternativa em relação a este, principalmente no primeiro período.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Henrique Pereira dosAmbrosi, IvoIgnaczak, João CarlosWobeto, CELSO1999-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5568Pesquisa Agropecuaria Brasileira; v.34, n.12, dez. 1999; 2175-2183Pesquisa Agropecuária Brasileira; v.34, n.12, dez. 1999; 2175-21831678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5568/2759info:eu-repo/semantics/openAccess2010-06-29T16:28:34Zoai:ojs.seer.sct.embrapa.br:article/5568Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-06-29T16:28:34Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
