Abstract:

This research was determined the effect of sowing dates on some agronomic and technological characters of safflower cultivars. The research was conducted in Samsun during the season 2017-2019 using 4 sowing dates (30 October, 14 November, 29 November and 14 December) and two safflower cultivars (Olas and Linas). The result of research, plant height 82.3-158.7 cm, the number of head 4.15 to 9.47 head-1 plant, seed weight per head 0.84 to 1.39 g, thousand seed weight 34.65 to 47.69 g, seed yield per plant 3.14 to 7.67 g, oil content 24.64 to 29.29% and oil yield per plant 0.83 to 2.25 g were determined. The result of interaction between sowing date and variety showed that for Olas variety the highest agronomic and technological traits were obtained in the 2nd sowing date, for Linas variety the highest values except for plant height and thousand seed yield were obtained in the 2nd sowing date. In addition, it was concluded that the second sowing date (14 November) is more suitable for safflower cultivation in the winter season in Samsun ecological conditions.
