Abstract :This study; was conducted during two yield seasons which are 1996/1997 and 1997/1998 seasons out in the ecological conditions of Haymana and to determine the effects of 3 different irrgation time and 4 different nitrogen fertilization levels (2-20 kg) on grain yield per unit area, 1000 seed weight, proportion of glassy grain, and protein content of grain on durum wheat varieties Kunduru-1149 and Berkmen-469. The experiment was carried out on fallow lands left out after wheat. The experiment was designed as random block strip plot design with three replications and the varieties were considered separately. The main plots were subjected to irrigation levels S1,S2, S3, sub plots were subjected to Ni-trogen levels N1, N2, N3. The highest grain yield per unit area of 429 kg/da during first year, 605 kg/da during 2nd year was obtained from variety Kunduru-1149. Whereas, the highest grain yields per unit area was 415 kg/da during first year and 482 kg/da during second year from variety Berkmen-469. These values were obtained after application of 20 kg/da N application in three splits with 9 kg/da at first application before sowing, 9 kg/da at initial stage of growth and 2 kg/da before tillering with three irrigations. The maximum 1000 grain weight, percentage of glassy seeds, the highest protein of variety Kunduru-1149 during first year was 59.50 g, 98%, 19.07% and 61.30 g, 95%, 15.93% during 2nd year respectively. The maximum 1000 grain weight, percentage of glassy seeds, the highest protein of variety Berkmen during first year was 51.10 g, 90.33%, 18.81% and 50.94 g, 74% and 15.81% during 2nd year respectively. It is concluded that under conditions of Central Anatolia, the highest grain yield in durum wheat could be obtained using three irrigations, summer fertilization with N at leaf emergence and tillering at the rate of 18 kg/da. As per results as yield and quality, the variety Kunduru-1149 should be preferred compared to Berkmen-469.Keywords : makarnalık buğday, camsı tane, protein oranı, bin tane ağırlığı, sulama, azotlu gübreleme
