Resumo: The objective of this work was to evaluate the response of green maize (Zea mays) intercropped with cowpea (Vigna unguiculata) to irrigation depths and phosphorus doses. The experiments were carried out in 2008 and 2009 in a randomized block design, with 25 treatments and four replicates. Treatments consisted of five irrigation depths at 70, 110, 140, 180 and 220% of the crop evapotranspiration, and of five doses of P2O5: 0, 50, 100, 150 and 200% of the recommended P dose. Maize was sown at 0.80x0.40 m spacing, and cowpea was planted inside the lines among maize plants. There was no effect of P2O5doses, but the response to irrigation depths was quadratic for maize and linear for cowpea. The maximum technical yield of green ears of maize with straw (10.76 Mg ha-1) and without straw (7.62 Mg ha-1) was obtained with 530 mm depth, intermediary to the 180 and 220% of the crop evapotranspiration. The highest cowpea green grain (3.40 Mg ha-1) was obtained with the highest water depth, of 644 mm

Os experimentos foram realizados em 2008 e 2009, em delineamento de blocos ao acaso, com 25 tratamentos e quatro repetições. Os tratamentos consistiram de cinco lâminas de irrigação, a 70, 110, 140, 180 e 220% da evapotranspiração da cultura, e de cinco doses de P2O5 a 0, 50, 100, 150 e 200% da dose de P recomendada. O milho foi semeado no espaçamento 0,80x0,40 m, e o feijão-caupi foi semeado dentro das linhas entre as plantas de milho. Não houve efeito das doses de P2O5; porém, a resposta às lâminas de irrigação foi quadrática em milho e linear em feijão-caupi. As máximas produtividades técnicas de espigas de milho verde com palha (10,76 Mg ha-1) e sem palha (7,62 Mg ha-1) foram obtidas com a lâmina de 530 mm, intermediária às lâminas referentes a 180 e 220% da evapotranspiração da cultura. A maior produtividade de grãos verdes de feijão-caupi (3,40 Mg ha-1) foi obtida com a maior lâmina de água aplicada, de 644 mm.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPqBlanco, Flávio FavaroCardoso, Milton JoséFreire Filho, Francisco RodriguesVeloso, Marcos Emanuel da CostaNogueira, Carlos César PereiraDias, Nildo da Silva2011-07-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/10052Pesquisa Agropecuaria Brasileira; v.46, n.5, maio 2011; 524-530Pesquisa Agropecuária Brasileira; v.46, n.5, maio 2011; 524-5301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/10052/6351https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/10052/5376info:eu-repo/semantics/openAccess2014-05-27T18:31:39Zoai:ojs.seer.sct.embrapa.br:article/10052Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-05-27T18:31:39Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
