Abstract:

This research was carried out in Erciyes University Agricultural Research and Application Center trial area in 2019 vegetation period (April-August) in order to determine the effect of different sowing densities on yield and quality in safflower cultivars (Carthamus tinctorius L.). The research, was conducted in "The Randomized Complete Block Design" with 4 replication, included 3 different row spacing and 7 safflower varieties: Dinçer, Asol, Göktürk, Yenice, Remzibey, Linas and Balcı. According to safflower varieties and row spacing, the first flowering period is 79.75-85.24 days, plant length is 52.7-87.17 cm, the first branch height is 29.35-59.40 cm, number of side branches per plant is 4.27-5.45, number of heads per plant is 5.0-7.4, diameter of head 16.76-19.56 mm, weight of head in plant 1.65-2.36 g, number of seeds per head 17.13-29.96 pieces, 1000 seed weight 34.65-42.49 g, seed yield 56.50-122.87 kg / da, oil rate in seed 24.64-37.10% and oil yield was determined to vary between 16.73-38.68 kg/da. According to the results of the research, it can be said that in 20 cm row spacing application, Dinçer variety from which was taken the highest average seed yield , and Linas variety from which was taken the highest average oil yield are more suitable cultivars for sufflower production in Kayseri conditions.
