Determination of the productivity and quality properties of some safflower varieties (Carthhamus tinctorius L.) in Bayburt conditions

This research was carried out in Bayburt province in 2021 to determine the yield and quality characteristics of some safflower cultivars (Carthamus tinctorius L.) in Bayburt Conditions. The experiment was carried out in three replications according to the Random Blocks Trial Design in the Bayburt University Organic Agricultural Management trial area. In the research, 8 different safflower varieties, namely Hasankendi, Zirkon, Balcı, Dinçer, Koç, Göktürk, Linas and Olas, were used as materials. In the experiment, plant height (cm), first branch height (cm), number of branches (number/plant), number of trays per plant (number/plant), tray diameter (mm), number of grains per tray (number/plate), thousand grain weight (g), grain yield (kg/da), husk rate (%), oil rate (%) and oil yield (kg/da) properties were investigated. As a result of the research; It was determined that safflower cultivars had significant effects on other investigated characters except for the diameter of the tray. The highest plant height and first branch height of Linas (66,11 and 35,83 cm, respectively) cultivar, the highest head diameter, thousand grain weight and number of seeds per tray Göktürk (2,62 cm, 43,89 g and 44,31 respectively) variety, the highest number of heads per plant was obtained from Olas (15,22 units/plant), the highest number of branches was obtained from Koç (9,44 units), and the highest bark rate was obtained from Dinçer (%57,38). When the grain yield, oil rate and oil yield values, which are important for safflower cultivars, are examined, the highest grain yield is Göktürk (164,00 kg/da) and Olas (156,33 kg/da) cultivars, the highest oil rate is Zircon (%35,5) variety and the highest oil yield was obtained from Olas (42,78 kg/da) variety. As a result, although it has been determined that the safflower cultivars Göktürk and Olas grown in Bayburt ecological conditions are in better condition in terms of yield and quality characteristics, we believe that it will be important to continue the adaptation studies for a few years in order to determine the response of the safflower plant to the years.
