Different ways of improving grain quality varieties of spring durum wheat in north and west zone of the Rostov region. The region is characterized by gradual climate change, which is reflected in the growth of its continentality. Studied four varieties of spring durum wheat – Volnodonskaya, Elegy of Don, Melody of Don. The precursor used legumes and winter cereals. The system of fertilizer provided the basic introduction of phosphate-based fertilizers for tillage, nitrogen (urea) in the late feeding on the leaf (heading stage). Seeding rates – 3, 4 and 5 million/ha. The results showed that the amount of protein in grain of spring wheat depending on weather conditions during the growing season. The more arid the conditions, the higher the amount of protein in the grain to 0,6%. Seeding rates have a definite impact on the amount of protein in the grain. However, this appears only when hard drought. Effective means of improving grain quality and rational use of mineral fertilizers. Based on the results obtained, it can be concluded that nitrogen fertilization increased the amount of protein in each class at any level of soil fertility. With medium to high level of mineral nutrition the amount of protein when feeding increased compared with baseline soil fertility at 0,2-0,4%, with a low power level of 0,5. The results of the experiment allow concluding that the loss in quality of grain of spring wheat associated with damage to her pests, in particular by turtle bug. quality of the wheat. Established a strong negative correlation between yield and protein content in grain of spring wheat. Sowing of spring wheat on the best predecessors (bean) allows you to increase the
