The effects of sowing dates on some traits including seed and oil yields, flower yield, plant height, Leaf Area Index (LAI), Crop Growth Rate (CGR) and Net Assimilation Rate (NAR), were studied. The results showed that late planting in safflower canopy caused a significant decrease in seed and oil yields. Combined analysis of two years, demonstrated that Padideh cultivar showed the highest grain and oil yields (2850 and 779kg/ha) at plant density of 40 plant/m2 in the first sowing date. Goldasht cultivar with 160 Kg/ha produced the highest flower yield at the highest plant density and first planting time (Sep20).
Key words: Safflower, sowing date.
