Determination of Yield and Quality in Some Safflower (Carthamus tinctorius L.) Cultivars Under Diyarbakır Ecological Conditions

Safflower oil is used as both cooking oil and industrial oil. Safflower is tolerant to cold, drought, and salinity conditions. This study was conducted to determine the safflower cultivars suitable for Diyarbakır ecological in conditions, and was performed during the 2014-2015, 2015-2016, and 2016-2017 growing seasons. The experiments were conducted in the trial field of “GAP International Agricultural Research and Educational Center. This experiment was designed according to the Randomized Block with three replications. Balcı, Dinçer, Linas, Olas and Remzibey-05 varieties were used in the experiment. Seeds were sown with 30 cm row spacing. In terms of three year average values, significant differences were observed at the 1 % level among the safflower varieties for plant height, head number per plant, thousand seed weight, crude oil ratio, and seed yield. According to the results, the highest seed yield was obtained in the Remzibey-05 cultivar (1882 kg ha−1), and the lowest yield was obtained from Balcı variety (1514 kg ha−1). In addition, plant height (110.2-116.7 cm), head number per plant (13.9-17.5), head diameter (2.18-2.21 cm), thousand seed weight (33.4-36.2 g), and crude oil ratio (26.67 - 35.75 %) were determined. To conclude, based on three years of study, it was observed that the Remzibey-05 cultivar could be recommended for Diyarbakır ecological conditions.
