Abstract: The purpose of the research is to increase the yield of spring durum wheat grain depending on the method of tillage in the conditions of the Volga forest–steppe. The methods of tillage were studied – plowing, loosening and without autumn tillage, and quantitative indicators – the completeness of seedlings, field germination, the number of plants before harvesting, the safety and survival of plants, biological yield and grain yield of spring durum wheat, as well as the accumulation of straw mass left on the field in the conditions of the Volga forest-steppe. In the plowing variant, the highest values of germination completeness, field germination, survival and preservation of plants were obtained. In the variants with loosening and without autumn mechanical tillage, the studied indicators had lower values: field ger-mination – by 0.6 and 2.9%, germination completeness – by 0.6 and 3%, plant survival – by 2.35 and 2.21%, plant safety – by 0.7 and 1.1%, biological yield – by 2.6 and 3.9%, grain yield – by 5.2 and 10.9%, straw weight – by 4.3 and 11.2%, respectively. The studied indicators of the production process, such as the fullness of seedlings, field germination, the number of plants before harvesting, the safety and survival of plants ensured the optimal, for the prevailing weather conditions, values of biological yield and grain yield of spring durum wheat, as well as the ac-cumulation of straw mass left on the field, depending on the tillage systems – plowing by 20-22 cm, loosening by 10-12 cm and without mechanical processing in the conditions of the forest-steppe of the Volga region. The coeffi-cients of correlation of yield with quantitative indicators – field germination r = 0.63, germination completeness r = 0.71, number of plants before harvesting r = 0.57, plant survival r = 0.75, safety from germination to harvesting r = 0.58 showed a close direct relationship of signs.
