Resumo: To analyse several production components of dry pea under different soil water regimes, some field experiments were carried out at Centro Nacional de Pesquisa de Hortaliças, Brasília, DF, Brazil, in the years of 85, 86, and 87. Sixteen factorial treatments resulted from applying four levels of soil water tension (25, 50, 100, and 200 kPa) in two stages of plant growing. Best productivities were found at 200 kPa of soil water tension on vegetative and reproductive stages, as a result of the greater grain size and smaller stand reduction. Seed germination was not influenced by soil water status. On the other hand, decoloration and rehydration capacity of grains were reduced as soil water tension increased during the reproductive stage.

Os tratamentos, dispostos num fatorial 4x4, resultaram da combinação de quatro níveis de tensão de água no solo (25, 50, 100 e 200 kPa) em dois estádios de desenvolvimento da cultura (vegetativo e reprodutivo). Na faixa de tensão estu­dada, a produtividade máxima foi obtida quando se permitiram tensões de até 200 kPa nos estádios vegetativo e reprodutivo, o que se deu em decorrência do maior crescimento de grãos e de uma menor redução de estande. A germinação de sementes não foi influenciada pelo status de água no solo, enquanto que a descoloração e a capacidade de reidratação de grãos foram reduzidas com o aumento da tensão de água no solo no estádio reprodutivo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMarouelli, Waldir AparecidoGiordano, Leonardo de B.Oliveira, Carlos A. da S.Carrijo, Osmar A.1991-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3437Pesquisa Agropecuaria Brasileira; v.26, n.7, jul. 1991; 1041-1047Pesquisa Agropecuária Brasileira; v.26, n.7, jul. 1991; 1041-10471678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3437/770info:eu-repo/semantics/openAccess2010-08-19T14:19:04Zoai:ojs.seer.sct.embrapa.br:article/3437Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-19T14:19:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
