Conteúdo:	Soybean cultivation is one of the main agricultural activities in Piauí, particularly in the Cerrado biome region. It is a rainfed crop, so the soybean sowing date is crucial to its good yield performance. This study aimed to make an evaluation using the CSM-CROPGRO-Soybean model to simulate soybean grain yield for the Cerrado region of southwest Piauí according to the different sowing dates. The CSM-CROPGROSoybean model and historical climate data were used to simulate scenarios for rainfed soybean, sowing dates for eight municipalities in the southwest region of Piauí. Two soybean cultivars were considered: BRS 8980 IPRO (BRS 8980) and the BMX 84I86 cultivar (Dominio). The simulated yield results were analyzed regarding frequency distribution and yield breaks. Sowings made in the first ten days of November had longer cycles, while later, sowings resulted in shorter cycles. This difference in duration was 16.4% for the BRS 8980 cultivar and 13.1% for the Dominio cultivar.
