Complex researches have been conducted in the Tver region on sod medium podzolic sandy loam well-cultivated soil. We have studied implementation of crop yield programmable levels by means of vetch-barley-oats mixtures different in composition. The advantage of their cultivation on grain-and-hay has been revealed, when the program both at the background of 2.5 thous. feed unit /ha and 5.0 thous. feed unit /ha on all variants of mixed crops was exceeded. Program has been carried out only at the programming level on 2.5 thous. feed unit / ha when growing mixtures for grain.
