Abstract: Faba bean is widely used in the Mediterranean region as source of protein in both human and animal nutrition. A legume member so fixes atmospheric nitrogen but with the assumption that nitrogen application to crops often results in yield improvement, a field experiment with N rates was conducted for two consecutive years. In the experiment 12 faba bean genotypes (KITIKI-2003, ERESEN-87, FİLİZ-99, SEVİL, SAKIZ, 95 ETA 225, 95 ETA 249, 95 ETA 276, 97 ETA 718, 97 ETA 727, 98 ETA 296 and 98 ETA 329) at 5 N rates (0, 50, 100, 150, and 200 kg ha−1) were evaluated for dry matter production and grain yield. Genotypes showed significant variation in grain yield and shoot dry weight. Genotype FİLİZ-99 was the highest yielding, whereas genotype SEVİL was the lowest yielding and the remaining genotypes were intermediate in grain yielding potential. Grain yield and shoot dry weight indicated significant quadratic relation with the increasing N rates between 0 and 200 kg ha−1.
