Field experiment was established according to the split plot in randomized complete block design with four replications under dry conditions in Konya. In the work carried out with the aim of determination of nitrogen use efficiencies (physiologic -NPE, agronomic-NAgE and uptake-NUE) of genotypes two treatments (control; 0 kg da-1 N and 8 kg da-1 N) and 8 bread wheat species (Gerek 79, Bezostaya 1, Altay 2000, Bayraktar 2000, Kate A–1, İzgi 2001, Sönmez 2001 and Karahan 99). In trial, nitrogen doses formed main plots and wheat varieties formed sub-plots. In the results of study, effects of N application on physiological, agronomic and uptake efficiency were found statistically significant. In addition, when the average N use efficiency of varieties analysed, while the highest physiological efficiency of N was determined in the Bayraktar 2000 (50.5), the highest agronomic and uptake efficiencies of N were found in the Kate A -1 (15.9 and 0.33). <br /> </p>}, number={4}, publisher={Van Yuzuncu Yıl University}, organization={Selçuk Üniversitesi Bilimsel Araştırma Projeleri Koordinatörlüğü}
