Resumo: The above ground biomass production and maximum yield (Ym) of sunflower were modeled based on theeffective temperature (Degree-Days) and photosyntheticaly active radiation absorved and accumulated (PARaa), under wellwatered conditions. Experiments were performed at a field sita at Taquari-RS, during two growth seasons 1991/92 and 1992/93. The energetic efficiency of sunflower was 2.457 grams of above ground dry manar per megajoule of PARaa during theperiod from emergence to the end of anthesis. The results also showed that the maximum yield of sunflower can be estimatedbased on the climatic normals of solar radiation and temperature for a given region.

Os experimentos foram realizados a campo no município de Taquari-RS, em duasestações de crescimento, 1991/92 e 1992/93. Os resultados mostraram que a eficiência energética do girassol é de 2,457g demassa de matéria seca aérea por megajoule de PARaa no período que vai da emergência das plantas até o final da antese.Ficou demonstrado que o rendimento máximo do girassol para uma dada região pode ser predito com base nas normaisclimáticas de radiação solar e temperatura do ar.Departamento de Diagnóstico e Pesquisa Agropecuária.
