Influence of methods of basic soil tillage on the contamination of soybean crops in Western Siberia

 Soybean is a new agricultural crop for Western Siberia. Agro-climatic conditions of Western Siberia are suitable for cultivation of early soybean varieties adapted to local conditions, but the yield of soybeans is small. The current situation dictates the need to develop a technology of cultivation of soybeans, which would provide a high productivity of this crop. One of the important tasks of tillage is to control weeds. The number of weeds significantly depends on the technology of the main tillage. Weeds reduce yields, inhibiting the growth and development of cultivated plants. Soybeans are very demanding on the quality of the main and pre-sowing tillage, because in the early stages of growth and development, it is subject to oppression from weed vegetation, which further adversely affects the production of high yields. The article presents data on the contamination of soybean crops depending on the method and depth of tillage for two years of research. The contamination of crops in the phase of soybean branching at zero tillage exceeded the control by 2.4 times, for non-dump processing (20–22) by 1.2 times, and for differentiated (20–22) by 0.61 times less compared to the control. As a result of the use of herbicide contamination of crops decreased in the dump (20–22) tillage on 13.5 pcs/m2 (81.8 %), with tillage (20–22) on 14.5 pcs/m2 (69.1 %), with differentiated (20–22) tillage on 9 pcs/m2 (90 %), for small-scale processing on 12.5–21 pcs/m2 (64.4–69.4 %), with zero on 28 pcs/m2 (69.1 %).
