Resumo: A field experiment was carried out in Sousa, PB, Brazil (6o45'33"S and 18o13'56"W) with an "AW" climate according to Köppen, to investigate the effect of row arrangement in cotton (Gossypium hirsutum L.r. latifolium Hutch.) and cowpea (Vigna unguiculata L. Walp. subsp. unguiculata) intercropping. All row arrangement in intercropping showed yield advantages in relation to pure stands of individual crops. Double rows (2:2) were the only row arrangements which satisfied the condition of 75% of the sole cowpea (the most valuable crop) with the highest total LER value (1:30). The alternate rows (1:1) and 2 rows of cotton/1 row of cowpea (2:1) satisfied the minimum condition of 50% of the sole cowpea with LER values of 1.17 and 1.25 respectively. Three rows of cotton/1 row of cowpea did not satisfy the minimum cowpea yield requirement but obtained a considerably high LER value of 1.25. None of the treatments affected consistently the plant growth and fiber quality of cotton.

Walp. subsp. unguiculata]. Todos os sistemas consorciados apresentaram consideráveis vantagens de rendimento em relação às testemunhas individuais das espécies isoladas. Fileiras duplas (2:2) foi a única modalidade de arranjo que satisfez a condição de 75% de rendimento de feijão e a que obteve mais elevado UET (1,30). Os arranjos de fileiras (1:1) e (2:1) satisfizeram a condição de 50% de feijão com UETs de 1,17 e 1,25, respectivamente. A modalidade 3:1, apesar de não satisfazer nenhuma das condições preestabelecidas de rendimento de feijão, apresentou considerável vantagem de rendimento em relação ao sistema isolado (25%). Os diferentes arranjos de fileiras não afetaram consistentemente o crescimento da planta nem a qualidade da fibra do algodão.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Azevedo, Demóstenes Marcos PedrosaBeltão, Napoleão Esberard de MacêdoVieira, Dirceu Justinianoda Nóbrega, Laudemiro Baldoíno1993-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3942Pesquisa Agropecuaria Brasileira; v.28, n.7, jul. 1993; 813-822Pesquisa Agropecuária Brasileira; v.28, n.7, jul. 1993; 813-8221678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3942/1233info:eu-repo/semantics/openAccess2011-08-23T15:05:49Zoai:ojs.seer.sct.embrapa.br:article/3942Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2011-08-23T15:05:49Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
