Effects of different plant spacing on yield and yield components of safflower (Carthamus tinctorius L.)

This research was conducted to determine the efficiency of different rows to rows (15,30 and 45 cm) and (5,10,15,20 and 25 cm) plant to plant distance of yield and quality parametersof safflower cultivar of Remzibey-05 under Diyarbakır conditions during growing season of 2013-2014 in the trial area of Field Crops Department, Faculty of Agriculture, University of Dicle.The research was carried out in 3 replications according to the design of "Split plot in Random Blocks". In this study, properties such as plant height, number of branches, number of capitula per plant, diameter of capitulum, number of seeds per capitulum, 1000- seed weight, seed yield, oil content, oil yield and protein content were examined. According to the results of the study, the highest seed yield and oil yield were obtained from 45 cm rows to rows and 5 cm plant to plant distance with (581.97 kg/da) and (160.05 kg/da) respectively. The highest oil content was obtained from the rows to rows 30 cm and plant to plant distance of 20 cm with (29.34%).
