Evaluation of efficiency machinery technologies for cultivation spring wheat in forest-steppe of Western Siberia

Recently, in agricultural production, combined sowing units have been widely used, combining a number of operations and reducing the number of passes in the field. The aim of the research was to conduct an agro technological comparative assessment of the sowing complexes equipped with various sowing working bodies under sowing spring wheat in the forest-steppe of the Omsk region. As a result of the studies, comparative observations were made of the quality of sowing according to four options for autumn tillage with the sowing unite Salford-1203 complex and the SSU-7.4 tillage sowing unit on two grounds using intensification and control. It was established that the average depth of seed placement in the sowing of spring wheat with disc coulters at the sowing unite Salford-1203 was 57 mm, and the SSU-7.4 aggregate was 65 mm. The reduction in the intensity of the main tillage from dump to zero when sowing SSU-7.4 led to a decrease in seedling density by 8-10.5%, and when sowing unite Salford-1203, the density of the emergence decreased to 5%...
