Resumo: Intending to define an intercropping system for annual cotton (Gossypium hirsutum L.r. latifolium Hutch), cowpea (Vigna unguiculata (L.) Walp) and sorghum (Sorghum bicolor (L.) Moench), four trials were carried out (two in 1984 and two in 1985) in Umarizal and Rafael Fernandes, RN, Brazil. The annual cotton/cowpea association presented a more efficient land utilization than the annual cotton/sorghum system. Cotton yield when intercropped with cowpea was less affected than when spatially distributed on a (2:1) arrangement. There was no difference regarding the yield as related to the cowpea populations studied. Cotton + cowpea in 2:1 arrangement with 40 thousand cowpea plants per hectare was the most efficient association. Annual cotton + sorghum systems didn't present feasible benefits in term of land equivalent ratio (LER).

Walp.) e sorgo (Sorghum bicolor (L.) Moench), foram instalados quatro ensaios: dois no ano agrícola de 1984 e dois em 1985, nos municípios de Umarizal e Rafael Fernandes, RN. A associação algodão herbáceo + caupi mostrou ser uma prática mais eficiente para intensificar o uso da terra do que a associação algodão herbáceo + sorgo. A produtividade do algodão herbáceo no arranjo espacial 2:1 foi significativamente superior à do algodão no arranjo 1:1. Os rendimentos do algodão nos sistemas algodão herbáceo + caupi foram menos afetados no arranjo 2A:1C, não tendo havido diferenças na sua produtividade em relação às populações de caupi estudadas. O sistema consorciado mais promissor agronômica e economicamente foi a associação algodão + caupi no arranjo 2A:1C com 40 mil plantas/ha de caupi.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNeto, Francisco BezerraFilho, José TorresHolanda, José Simplício deSantos, Edvaldo FerreiraRosado, Carlos Alberto de Sousa1991-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3396Pesquisa Agropecuaria Brasileira; v.26, n.5, maio 1991; 715-727Pesquisa Agropecuária Brasileira; v.26, n.5, maio 1991; 715-7271678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3396/729info:eu-repo/semantics/openAccess2009-12-08T16:29:13Zoai:ojs.seer.sct.embrapa.br:article/3396Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2009-12-08T16:29:13Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
