The research was conducted in the northern forest-steppe of Kuznetsk Depression in a threecourse grain-fallow crop rotation (fallow-wheatpeas-barley, barley intercropped with melilot) in a long-term stationary experiment. Various soil tillage systems were applied (deep moldboard, deep combined, minimum combined, minimum moldboard) preceded by bare fallow and green-manured fallow with rape and melilot. The soil of the experimental plot was leached chernozem. Crops of spring common wheat were sown with all types of soil tillage systems by the tillage and sowing machine Tom’5.1. It was revealed that the main factor influencing the yield of spring common wheat is water availability in the planting periods – full tillering, (r = 0.9579), beginning of earring – yellow ripeness, (r = 0.9611; R = 0.9500). A positive effect on wheat productivity was made by cellulosolytic activity and soil structure. The direct correlation between these factors and the crop yield was established, r = 0.6366 – 0.7298 and r = 0.6343 – 0.7103 respectively. A negative effect on the yield of wheat was made by the development of root decay (Bipolaris sorokiniana (Sacc.) Shoem), (r = – 0.4808). It was established that alongside the above-mentioned fac tors, the significant effect on productivity of spring common wheat was made by the systems of soil tillage (72.4%,) and the predecessor (22.0 %). The optimum conditions in agrocenosis of spring common wheat for formation of its yield during the years of research proved to be created by green-manured fallow (with rape) with minimum moldboard and deep moldboard soil tillage (2.72 and 2.78 t/ha respectively), which is 0.55 and 0.51 t/ha higher compared to analogous soil tillage systems preceded by bare fallow – control. Minimum moldboard soil tillage has an economic advantage over others with profitability of 193.6% and production cost at 5,000 rubles per 1 ton of grain.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>яровая пшеница</kwd><kwd>система обработки почвы</kwd><kwd>урожайность</kwd><kwd>лимитирующие факторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spring common wheat</kwd><kwd>soil tillage system</kwd><kwd>yield</kwd><kwd>limiting factors</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">ПетровскийН.В.,РомановВ.Н.,Литау В.М., Ивченко В.К.
