Resumo: | The recent literature on field experimentation in the state of Rio Grande do Sul, Brazil, with early sunflower cultivars sown in the beginning of spring, has shown the possibility for the obtention of economic yields in that state for the springtime. Considering those cultivars and this sowing time, most of the state area is climatically suitable for sunflower. Adopting the criteria of the sum of the degree-days above 50, higher than 1,400°C, and water deficiency in summer below 25 mm, three regions were identified; the largest one is the north-central part, with no climatic restrictions and considered perfect for that culture; the southern and litoral regions with a small water deficiency in summer but with economic yields, and the northeast highlands; and a small region, suitable only for very early cultivars due to a lack of heat for the maturation of other cultivars. |

Considerando estas cultivares e esta época de semeadura, a maior parte do Estado apresenta condições climáticas adequadas para o plantio do girassol. Com a adoção da soma dos graus-dias acima de 5 ºC, superior a 1.400 ºC e a deficiência hídrica no verão, inferior a 25 mm, foram identificadas três regiões quanto à sua aptidão climáfica para a cultura do girassol; a maior delas ocupa a parte centro-norte, sem restrições para a cultura, sendo considerada plenamente apta; a região sul e o litoral apresentam uma pequena deficiência hídrica no verão, que, entretanto, não impede a obtenção de rendimentos econômicos; e, uma pequena região na serra do nordeste do Estado, com falta de calor, sendo adequada apenas para cultivares muito precoces.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMota, Fernando Silveira da2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13335Pesquisa Agropecuaria Brasileira; v.25, n.1, jan. 1990; 39-42Pesquisa Agropecuária Brasileira; v.25, n.1, jan. 1990; 39-421678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13335/7512info:eu-repo/semantics/openAccess2014-04-17T14:24:18Zoai:ojs.seer.sct.embrapa.br:article/13335Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:24:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
