Conteúdo: 	The southernmost region of Brazil (Rio Grande do Sul State) lies between 27oS and 33oS, the most productive areas being located between 27oS and 33oS. Average annual percipitation range from 1300 to 1700mm, distributed along the year. Average temperature varies from 25oC (January) to 11o (July). Sunflower can be grown from August to April in the warmest areas (low altitude). Best results have been obtained when the crop is established during August/September. Besides better yields and oil content (35 to 40%), disease incidence is low and the frequently occurring mid-summer short dry-period can be avoided. Harvest can be proceeded during December-January, allowing a second summer crop in the same growing season. Seeding after october results in low yields an lowoil content. This is due to higher disease incidence (mainly rust) and low rainfall. If seeding is done late in the season (January), the cooler temperatures can restrict yield and oil accumulation. There are good perspectives to reintroduce the sunflower crop in this area based on adequate yields (2000 to 3000 kg/ha) in experimental plots) and high oil content. By antecipating the seeding date, some of the problems that determined the decline of the crop in the past can be avoided. Harvest date makes seeds available for processing in a period of high demand by the oil extraction industry.
