Abstract: The aim of this study was to evaluate the effects of N levels on chemical composition and energy content of different barley varieties grown under north Anatolian arid condition. Experiment was established as a split-plot design in a randomized complete block, with three replications. Five different winter type barley varieties (Bülbül 89, Tarm 92, Tokak 157/37, Yesevi 93 and Aday 1) were utilized. Five nitrogen levels (0, 45, 90, 135 and 180 kg ha 1) were also applied to each variety. Barley were harvested by hand using a clipper and air-dried. Then, grains were separated from straw and yields were determined. Grains were analyzed for DM, OM, CP, CF, EE, and IVOMD. NFE, ME, NEL values were also calculated. N fertilization had significant effect on concentrations of CP, CF, EE, total and grain yields (p<0.01). The concentrations of DM, CP, CF, NFE and IVODM and total yields were significantly different among barley varieties (p<0.05). In conclusion, approximately 90 kg N/ha seemed to be most proper N levels in general Tokak 157/37, Tarm 92, and Bülbül 89 varieties seemed to be most consistent varieties for the region.
