Investigation of yield and yield components of safflower (Carthamus tinctorius L.) genotypes sown at different seasons under yozgat conditions

This research was conducted during 2013-2014 in different seasons using randomizde block design with three replications aiming to determine the most suitable safflower cultivar for Yozgat conditions and therefore the yield and yield components of three reeased safflower cultivars (Dinçer, Remzibey 05 and Balcı) were detrmined. The variation was determined comparing winter and spring sowings in this three cultivars. According to the results of the study; whereas in spring sowing the obtained values were 51,29 cm for plant height, first height of branching 28,67 cm, number of branches 4,156, number of heads per plant 8,111, thousand seed weight 56,05 g, seed yield 96,44 kg/da, crude oil yield 24,44 kg/da, protein yield 12,86 %, flower yield 9,51 kg/da, oleic acid 17,43 %, linoleic acid 72,68 % and linılenic acid 0,56 %; the values for autumn sowing were 63,74 cm plant height, 32,1 for height of first branching, 8,83 for number of branches, 18,75 for number of heads, 58,73 g for thousand seed weight, 209,37 kg/da for seed yield, 50,44 kg/da for crude oil yield, 33,61 % for protein yield, 16,93 kg/da for flower yield, % 19,93 for oliec acid, 19,93 for linoleic acid and 0,5 % for linolenic acid. The highest yielding cultivar was determined as Dinçer with an seed yield of 310,792 kg/da in winter sowing ranking before the cultivars remzibey-05 and Balcı.
