Resumo: Three experiments were carried out under soil and climate conditions of Central Brazil to determine the adequate time to stop irrigations for carrot seed production. The treatments consisted of stopping irrigations at 60, 70, 80, 90, 100, 110, 120, 130 and 140 days after planting. Carrot seed production was found to be a quadratic function of time to stop irrigation. Large productivities were found when irrigation was stopped at 121 days after planting. Irrigation costs were optimized at this time. The weight of 1.000 seed and the crop cicle increased with the time to stop irrigations. Seed germination was not affected by the treatments.

Brasília, pelo sistema raiz-semente. As irrigações foram paralisadas aos 60, 70, 80, 90, 100, 110, 120, 130 e 140 dias após o plantio. A produtividade de sementes apresentou relação quadrática com a época de suspensão das irrgações, sendo observado um valor máximo quando as irrigações foram interrompidas aos 121 dias, época esta que também possibilitou uma otimização dos custos de irrigação. O ciclo da cultura e o peso de 1000 sementes aumentaram linearmente, quanto mais tarde foram paralisadas as irrigações. A germinação de sementes não foi afetada pelos tratamentosPesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMarquelli, Waldir A.Carrijo, Osmar A.Oliveira, Carlos A.S.2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13400Pesquisa Agropecuaria Brasileira; v.25, n.3, mar. 1990; 299-303Pesquisa Agropecuária Brasileira; v.25, n.3, mar. 1990; 299-3031678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13400/7543info:eu-repo/semantics/openAccess2014-04-17T14:30:40Zoai:ojs.seer.sct.embrapa.br:article/13400Revistahttp://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
