Effect of Different Doses of Nitrogen on the Yield and Yield Components of Safflower (Carthamus tinctorius L.) under Ankara Ecological Conditions

16209

This study was conducted with Dinçer Safflower variety in Ankara ecological conditions in 2010 and 2011. The experiment was established with randomized complete block design with tree replications. Nitrogen doses are N1:0,0, N2: 2,5, N3:5,0, N4:7,5, N5:10,0, N6:15,0 and N7:20,0 kg/da. Plant height (cm), number of heads per plant (number), 1000 seed weight (g), seed yield (kg/da), oil content (%) and oil yield (kg/da) were investigated in the experiment. According to results of this research, nitrogen dose, years and year X dose interactions had positive impacted on the plant height, number of heads per plant, 1000 seed weight, oil content, seed and oil yield. The highest plant height was obtained from X N6 dose interaction (79,70 cm) in 2011. The maximal seed yield (231,20 kg/da), oil content (% 30,50) and oil yield (70,57 kg/da) were obtained from X N7 dose interaction treatment in 2011.
