Abstract
Modern agriculture in Western Siberia requires a scientifically justified approach to selection of soil treatment method. Switching to new soil treatment methods without considerations for soil and climate features of the region leads to unpredicted results and reduced crop yields. The research objective is to study the primary tillage systems in Western Siberia. The experiments were conducted at the research station of the Northern Trans-Urals State Agricultural University, located in the northern forest-steppe of Tyumen oblast. The studied methods included moldboard plowing, non-moldboard loosening and a No-till technology as applied to spring wheat plots. It has been established, that on average the wheat yields amounted to 3.54 t/ha for the 5 years of research. Under the nonmoldboard loosening at 20-22 cm, the grain yield reduced by 12% as compared to the plowed patch. Use of No-till technology in Western Siberia led to an abrupt drop in spring wheat yield. One of the causes leading to lower grain yields is weed infestation of the fields. Under plowing, the number of weeds and their relative share in the agrophytocenosis is minimal. Abandoning crop rotation led to increased weed infestation, despite chemical weeding. In the patch under No-till, the weight of weeds amounted to 1.62 t/ha before the wheat harvest, which is 19% of agrophytocenosis; for the plowed batch, this value was 12%. The research has found that No-till technology is unsuitable for Western Siberia.
