A field experiment was conducted during the winter season for the year 2021-2022 in two locations: the first in the fields of the College of Agriculture and Forestry / University of Mosul and the second in the Badoush Dam location with the aim of studying the effect of three row spacing between lines (30, 45, 60 cm) and three safflower varieties (Gila, Almis, Jordanian) on growth and yield traits. The experiment was applied as a factorial experiment with a randomized complete block design (RCBD) with three replicates. The results showed that there were significant differences between the row spacing in most of the studied traits for both experimental location .The row spacing of 30 cm gave the highest value for plant height in the Badush Dam location, and the distance of 45 cm gave the highest value for the number of seeds/head in both locations .While the row spacing of 60 cm gave the highest value for the number of branches/plant, leaf area, weight of 1000 seeds, seed yield, oil percentage, and oil yield in both experimental location, and the number of heads/plant in college location. The varieties had a significant effect on all studied traits and for both location of the experiment, where Gila cultivar recorded the highest value of 1000 seed weight in both location,While Almis cultivar recorded the highest value for plant height, number of branches/plant, leaf area, number of heads/plant, number of seeds/head, seed yield, and oil percentage and yield.The interaction between cultivation distances and varieties was significant in most of the studied traits.The row spacing was 60 cm, and the Almis cultivar was higher as a result of the number of branches/plant in college location, leaf area in Badush Dam location, and seed yield in both locations.
