Abstract
Plant characters related to the utilization of nitrogen were investigated in fifteen barley genotypes. The results showed that differences among the genotypes for all characters were significant. Grain yield, total N yield and grain protein content of genotypes ranged between 2186 and 3222 kg.ha−1, 72.7 and 102.3 kg.ha−1, 12.01 and 13.27 %, respectively. Tokak 157/37 had the highest uptake (1.28 kg N uptake/kg N applied), translocation (72.1 %) and agronomic (40.3 kg grain/kg N applied) efficiency of N. The highest physiological efficiency was obtained from cv. 1515 (32.5 kg grain/kg N uptake). Thus, the potential for developing superior, N efficient genotypes appears to exist.
