Summary: The availability of productive varieties, the use of oil for food and fuel purposes, and the utilization of protein meal as feedstuff source, respectively, promote the oilseed sunflower (Helianthus annuus L.) crop in southern Brazil; but certain factors limit yield. Apart from other agronomic problems, one limiting constraint is planting date. In order to study this, four sunflower varieties were seeded monthly from August to December, and from October to January, respectively in 1982 and 1983/84 seasons on Planossol (Albaqualf) soil at the Centro de Pesquisa Agropecuária de Terras Baixas de Clima Temperado (CPATB-EMBRAPA) Experiment Station, in Capão do Leão county (31ºC52' S), RS, Brazil. Eight field trials and bench tests were performed to evaluate this practice on growth duration, seed and oil yields, and oil percentage. The early planting time (late winter and early spring) proportionates better grain yield and oil percentage in the grain, although the elongation of growth duration. This was attributed to favorable temperature and soil moisture incidence during blooming. Early planting promotes, additionaly, healthy crops and raw-material to oil industries in the off-season (from November to February).

Entretanto, entre outros problemas agronômicos, a época de semeadura é um entrave à sua produtividade. Visando estudar essa limitaçáo, quatro cultivares de girassol foram semeadas mensalmente, de agosto a dezembro de 1982 e de outubro a janeiro de 1983/84, em solo tipo Planossolo, do Centro de Pesquisa Agropecuária de Terras Baixas de Clima Temperado (CPATB-EMBRAPA), em Capão do Leão (31°C 52' S), RS. Oito experimentos de campo e testes de laboratório possibilitaram avaliar o efeito dessa prática sobre: ciclo vegetativo, rendimento de grãos, de óleo e a concentração de óleo. A semeadura de final do inverno e/ou início da primavera proporciona rendimentos de grãos e percentagem de óleo elevados, embora aumente o ciclo vegetativo das plantas. Níveis favoráveis de temperatura e umidade do solo, durante a floração, influenciaram essa produtividade. O cultivo precoce proporciona, adicionalmente, lavouras sadias e grãos na entressafra industrial da soja.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilveira, Expedito PauloAssis, Francisco Neto deGonçalves, Paulo RomeuAlves, Gilmar Chaves2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13485Pesquisa Agropecuaria Brasileira; v.25, n.5, maio 1990; 709-720Pesquisa Agropecuária Brasileira; v.25, n.5, maio 1990; 709-7201678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13485/8128info:eu-repo/semantics/openAccess2013-03-04T12:59:55Zoai:ojs.seer.sct.embrapa.br:article/13485Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-03-04T12:59:55Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
