This study carried out to determine the effect of plant
densities on some agronomic characteristics of four safflower cultivars in spring planting. The experiment was conducted at Yazd,
Iran using a factorial in a randomized complete block design with four replications. Cultivars were including Arak, IL, Asteria and Local and plant densities were 10, 13.3, 20 and 40 plantm2. Number
of seedshead, number of headsplant, HI, 1000seed weight and seed yield significantly decreased as planting density increased. With increasing planting density, LAI, plant height, first branch height and
biological yield increased. The highest seed yield was obtained in 13.3 plantm2 (2167 kgha). There were significant differences
between cultivars. Local cv. had higher seed yield than the other cultivars mainly due to higher headsplant and seedshead.
