THE EFFECT OF NITROGEN ON THE GRAIN YIELD OF GEREK-79 AND BEZOSTAYA-1 BREAD WHEAT WARIETIES UNDER LEGUME-WHEAT SYSTEM IN NORTHERN TRANSITIONAL ZONE OF CENTRAL ANATOLIA
Öz
The results of 14 experiments conducted in Northern Transitional Zones of Central Anatolia to obtain the optimum N rates for Gerek-79 and Bezostaya-1 bread wheat varieties showed that increased N application resulted in statistically significant increases in grain yields. However the effect of nitrogen differed among the locations. N requirements for wheat varieties were predicted using equations obtained under different precipitation leves at various growing periods of wheat varieties. Thus, 250 mm, 350 mm and 450 mm precipitation levels resulted in 8.6 kg/da, 12.6 kg/da and 15.1 kg/da economic N requirements for Gerek-79; 9.4 kg/da, 10.6 kg/da and 11.8 kg/da for Bezostaya-1, respectively.
