Comparative assessment of sowing complexes in the growing of grain crops in Western Siberia

The article describes the comparative technical-operational assessment of the parameters of sowing complexes with powerful tractors in comparison with K-701 + 6SKP-2,1 (control variant) in the growing of spring wheat in the south forest-steppe of Western Siberia agro landscape. The seasonal productivity of sowing complexes with powerful tractors in 2.5-4.5 times exceeded the parameters of performance the control aggregate and reduced the operating costs by 15-27% were distinguished. A distinctive feature of cultivated multifunctional complexes is a way of sowing, which depends on the design of the coulter. It has been established that the selection of the type of coulters to ensure a quality way of seeding, is largely determined by the applicable farm tillage technology. The choice of types of cultivated plants and ways of planting grain crops depending on the basic and pre seeding soil tillage were recommended.
