Resumo: The model Cropgro-soybean was calibrated for cultivars CD 202, CD 204, CD 206 and CD 210 in the municipality of Palotina, State of Paraná, Brazil (24º17'S latitude, 53º50'30'' longitude and 333 m altitude). After calibrated, the model Cropgro was used to estimate soybean yield for five planting times, during 25 years (1974 to 1999). Sensitivity analysis of the model showed high response due to changes in genetic coefficients of the cultivars in this study. The highest crop yield was simulated for October 1, but it also gave the lowest estimates. The best planting dates were found to be October 15 and November 1, with mean yields of 2.450 kg ha-1 and 2.303 kg ha-1, respectively.

Após a calibração, o modelo Cropgro foi usado para estimar a produtividade de soja para cinco datas de semeadura, durante 25 safras (1974 a 1999). Análises de sensibilidade realizadas revelaram alta resposta do modelo à variação dos coeficientes genéticos dos cultivares estudados. Das cinco datas de semeadura simuladas, a que apresentou as maiores produtividades foi a de 1 de outubro, porém foi a que também apresentou as menores produtividades. As melhores épocas de semeadura foram consideradas 15 de outubro e 1.º de novembro, por apresentarem médias dos quatro cultivares de 2.450 kg ha-1 e de 2.303 kg ha-1, respectivamente.Universidade Estadual de Maringá2008-02-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/93610.4025/actasciagron.v28i4.936Acta Scientiarum.
