In order to investigate the possibility of early sunflower sowing in the cold temperate regions of Kermanshah province, the current research was conducted in the agricultural research station of Mahidasht in the cropping season of 1401-1400. In this research, five planting dates and four cultivars were evaluated. In this research, important agricultural traits including seed yield, thousand seed weight, number of days to flowering, duration of flowering, number of days to physiological maturity and seed yield were evaluated. The results of simple variance analysis of the data showed that the planting date had a significant effect on all the evaluated traits. The studied cultivars also had significant differences in terms of all studied traits. Comparison of average data showed that the highest seed yield with 3921 and 3720 kg per hectare belonged to the planting dates of Ordibehesht 10 and Farvardin 25, respectively. The calculation of the physical and economic productivity of water in different planting dates showed that the planting dates of Farvardin 10 and 25 have high economic productivity due to saving the amount of water consumed and low risk of environmental stress. The results of the present research showed that according to seed yield and productivity, the most suitable date for sunflowersowing in the cold temperate regions of Kermanshah province is the first decade of Farvardin onwards and Lakomka variety is the most suitable variety for cultivation
