Resumo: The effects of six irrigation treatments and two soil-water tension measurement depths (15 cm and 30 cm) on bean (Phaseolus vulgaris L.) yield were studied. The irrigation treatments consisted of irrigating when soil-water tension reached 125, 250, 375, 500, 625, and 750 mb. There was no significative difference in bean yield when irrigation scheduling was based on soil water tension measurements made at 15 cm or at 30 cm depths. After initial stand establishment, final plant population was not influenced by irrigations carried out at different soil-water tensions. On the other hand, the number of pods per plant, seeds per pod and grain yield decreased as the soil-water tension increased. The intensity of yield decrease depended on the environmental evaporative demand.

Os tratamentos de irrigação consistiram em irrigar o feijoeiro quando a tensão matricial da água do solo atingisse 125, 250, 375, 500, 625 e 750 mb. Não houve diferença significativa com relação à produtividade do feijoeiro, quando a tensão da água do solo foi controlada a 15 cm ou 30 cm de profundidade. A população final de plantas não foi afetada pelos tratamentos de irrigação, quando o "stand" inicial foi adequado. O número de vagens por planta, o número de grãos por vagem e a produção de grãos, entretanto, decresceram à medida que as irrigações foram feitas a tensões crescentes da água do solo. A intensidade do decréscimo de produção dependeu da demanda evaporativa do ambiente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraStone, Luís FernandoMoreira, José Aloísio AlvesSilva, Silvando Carlos da2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13794Pesquisa Agropecuaria Brasileira; v.23, n.2, fev. 1988; 161-167Pesquisa Agropecuária Brasileira; v.23, n.2, fev. 1988; 161-1671678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13794/7832info:eu-repo/semantics/openAccess2014-09-05T19:00:25Zoai:ojs.seer.sct.embrapa.br:article/13794Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-05T19:00:25Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
