Sowing Time, Variety and Yield Relationship in Safflower

This research which aims to determine the performances showed in the autumn and spring sowing times of four different safflower varieties was carried out during 2013-2015 years. the study has arranged according to the split plot trial design in randomized complete block as three replications. in the study,plant height, number of side branch attached to main branch, head number per plant, seed number in the head, 1000 seed weight, seed yields and, correlation relationships in the between of this characteristics were examined. sowing time for examined all characteristics has established significant differences. superior performances to spring sowings from autumn sowings were obtained. remzibey-05 variety has received first place in terms of number of side branch attached to main branch,head number per plant seed number in the head and seed yield. when consideringtheperformancesof varieties according tosowing times, the highest seed yield was given remzibey-05 variety sown in the autumn with 3156.6 kg ha^-1. yenice variety that sown in the spring has occured the lowest seed yield with value 1098.3 kg ha^-1.
