In order to determine the appropriate planting date and evaluate the effect of sulfur on yield and yield components of pumpkin (Cucurbita pepo L. ), a factorial experiment was conducted based on a randomized complete block design with three replications and two factors in Khalilabad, Khorasan Razavi, in 2016 cropping year. The experimental factors were three planting dates (20 and 30 April and 10 May) and application of granular sulfur at four levels (0, 150, 300, and 450 kg ha-1). The results showed that planting date significantly affected the main stem length, branch number, total biomass, number of seeds per fruit, seed weight per fruit, 1000-seed weight, fruit and seed yield per hectare and oil percentage. Delayed planting from 20 to 30 April decreased the weight of 1000-seed by 14%. The highest seed yield was achieved by applying 300 kg sulfur per hectare. The fruit yield and seed oil percentage were higher in the first planting date and application of 300 kg sulfur ha-1. In general, this study showed that the first planting date (20 April), with the application of at least 300 kg ha-1 of sulfur fertilizer, would provide the best conditions for pumpkin yield.
