Resumo: Field experiments were conducted in 1990 and 1991 in Tucson, Arizona, to examine the effects of spatial arrangement and density on yield and biomass of an annual cotton/cowpea/maize intercrop. In the 1990 experiment, treatments were combined in an unconfounded 4 x 4 factorial, which consisted of four spatial arrangements of cotton, cowpea, and maize crossed with four cowpea/maize densities. In the 1991 experiment, treatments were combined in an unconfounded 5 x 2 + 1 factorial, which consisted of five densities of cotton crossed with two densities of cowpea and maize, plus one additional treatment. The results of these experiments indicate that component-crop yield and biomass in an annual cotton/cowpea/maize intercrop can be significantly affected by the manipulation of spatial arrangement and density as management factors. The most appropriate arrangements and densities in particular circumstances depend on either the combined intercrop yield and biomass or the yield and biomass of a specific component crop that is more highly valued.

No experimento de 1990, estudaram-se quatro arranjos espaciais de algodão, caupi e milho, e quatro densidades de caupi e milho em um delineamento fatorial 4 x 4. No experimento de 1991, estudaram-se cinco densidades de algodão e duas densidades de caupi e milho, mais um tratamento adicional, em um delineamento fatorial 5 x 2 + 1. O rendimento e a biomassa das culturas componentes em um consórcio algodão herbáceo/caupi/ milho podem ser afetados de maneira significativa pelo manejo do arranjo espacial e da densidade de plantas. Os arranjos espaciais e as densidades de plantas mais adequadas dependem do rendimento e da biomassa total do consórcio ou do rendimento e da biomassa de uma cultura componente específica que tenha preço mais elevado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNeto, Francisco BezerraRobichaux, Robert H.1997-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4752Pesquisa Agropecuaria Brasileira; v.32, n.10, out. 1997; 1029-1037Pesquisa Agropecuária Brasileira; v.32, n.10, out. 1997; 1029-10371678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/4752/7284info:eu-repo/semantics/openAccess2015-03-27T20:08:11Zoai:ojs.seer.sct.embrapa.br:article/4752Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-27T20:08:11Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
