Effects of sowing date and plant population on seed yield of Cucurbita pepo L. were investigated. The experimental treatments included plant population at three levels (0.6, 1.3 & 2.2 plant m-2) as the main plot and sowing date at three levels (April 18, 29 & May 9) as the sub-plot. Seed yield per unit area, the number of seeds per fruit, fruits per plant, flowers per plant and auxiliary branches per plant were recorded. The highest seed yield was recorded in plots having 2.2 plant m-2 sown on April 18. Thus, present results revealed that suitable plant density cannot improve yield and yield components of pumpkin if sowing date was delayed.
