The dependencies of yield and grain quality of durum wheat were studied, depends on nitrogen fertilization at rates 0, 60, 80, 100, 120, 140, 160 and 180 kg/ha. It was found that structural elements of the yield length of the spike, number of spikelets per spike, grains per spike, grain weight per spike, productivity grain and grain protein, and grain quality concentration of protein in the grain, content of wet and dry gluten, total vitreousness of the grain were in a strong positive correlation with N applied at rates 0 пїЅ 180 kg N/ha and 1000 kernel weight and test weight of grain less depended on nitrogen fertilization. Grain and protein yields strongly and positively associated with the structural elements of the yield and grain quality parameters without the 1000 kernel weight and test weight. Without nitrogen of durum wheat might expected grain yields of 330.8 kg/ha and grain protein yields 43 kg/ha. The potential additional yield per kg N input per hectare was 13.1 kg grain and 1.99 kg grain protein. From durum wheat grain without nitrogen fertilization was projected grain containing total vitreousness 59.9%, crude protein concentration пїЅ 13.2%, wet gluten content of 24.3% and dry gluten пїЅ 8.89%.
