Productivity of crops of grain-tilled crop rotation in the northern forest-steppe of the Tyumen region
The article presents five-year results on the study of the influence of the methods of basic tillage on the yield and productivity of crops of grain-tilled crop rotation in the northern forest-steppe of the Tyumen region. The research is presented on the experimental field of the State Agrarian University of the Northern Trans-Urals in 2016 - 2020. The soil is leached chernozem. Three methods of basic soil cultivation (dump, dump-free, differentiated) in a three-field crop rotation were studied: corn - spring wheat - oats. The corn yield over the years of research for the studied options varied from 27.31 to 28.91 t/ha. The yield of grain crops by methods of soil cultivation ranged from 3.01 to 4.55 t/ha. The highest productivity was noted in the control variant - 4.75 t feed u/ha, which is 0.59 t feed u/ha higher than in the case of the moldboard-free method. It has been established that the moldboard method of soil cultivation increases the productivity of crops of grain-row crop rotation in the northern forest-steppe of the Tyumen region.
