Resumo: Field experiments were carried out at CNPH-EMBRAPA in 1984, 1985, and 1986 with the objective of establishing soil moisture management for carrot (Daucus carota L.) seed production, based on soil water tension. Treatments consisted of refilling the root zone with water as soil water tension reached values of 25, 50, 100, 200, 400, 800 and 1.500 kPa, at 10 cm depth till flowering and at 20 cm depth after that phase. Regression analysis allowed to conclude that maximum seed productivity was obtained when irrigation was applied each time soil water tension reached 75 kPa. Economical water tension was found to be 80 kPa. Stand, germination and weight of 1.000 seeds were found not to be significantly influenced by the treatments

Os tratamentos consistiram em irrigar quando as tensões, na profundidade de 10 cm até o florescimento e de 20 cm após este estádio, atingiam 25, 50, 100, 200,400, 800 e 1.500 kPa. A análise de regressão indicou que a produtividade máxima de sementes foi obtida com a tensão de 75 kPa, enquanto a tensão ótima econômica foi estimada cm 80 kPa. O estande, a taxa de germinação e o peso de 1.000 sementes não foram influenciados pelas diferentes tensões.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMarquelli, Waldir A.Oliveira, Carlos A.S.Silva, Washington L.C.2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13406Pesquisa Agropecuaria Brasileira; v.25, n.3, mar. 1990; 339-343Pesquisa Agropecuária Brasileira; v.25, n.3, mar. 1990; 339-3431678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13406/7547info:eu-repo/semantics/openAccess2014-04-17T14:30:40Zoai:ojs.seer.sct.embrapa.br:article/13406Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:30:40Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
