Abstract :To improve grain yield and quality of irrigated winter durum wheat insert ignore into journalissuearticles values(Triticum durum L. cv. Kızıltan-91);, this study was conducted to determine the optimal amount and timing of nitrogen fertilization. Experiments were carried out in 1997-98 and 1998-99 growing seasons with irrigated winter durum wheat in Konya Region, Central Anatolia, Turkey. The amounts of nitrogen were 50, 100, 150 and 200 kg N ha-1 versus control. Timings of nitrogen were “the all at sowing”, “1/2 at sowing + 1/2 at stem elongation”, and “1/3 at sowing + 1/3 at stem elongation + 1/3 at boot stage”. The highest grain yield was obtained with the applications of 150 kg N ha-1 increasing from 3490 and 3060 kg. ha-1 to 4540 and 4150 kg. ha-1 in 1997-98 and 1998-99 seasons, respectively insert ignore into journalissuearticles values(P<0.01);. Split applications of nitrogen increased the grain yield over the single application, the all at sowing. Grain yield for the two seasons were 4380 and 4050 kg ha-1 in the third application timing while it was 3870 and 3600 kg ha-1 in the first application timing insert ignore into journalissuearticles values(all at sowing);, respectively insert ignore into journalissuearticles values(P<0.01);. Protein concentration was increased insert ignore into journalissuearticles values(3 %); by nitrogen application. Split application of nitrogen increased insert ignore into journalissuearticles values(1 %); protein con-centration over single application.
