to the naked forms of these cereals (Table 4). Vetch yields best in a mixture with wheat, but
triticale is also a good component for this legume crop (Figure 1). Other studies show, however,
that spring barley is a better component for self-finishing cultivar of vetch compared to oats
[37]. Lupines yield good in the mixtures with spring triticale and spring wheat, but poorly in
the sowings with oats. In the mixture with oats, the yields of lupine seeds are low and variable
in years, and their share in the yield of mixtures usually does not exceed 10%. In addition,
yellow lupine proves to be more useful for mixtures with spring cereals than blue lupine [38,
39, 40].

On better soils, the choice of cereal species for the mixtures with peas is less important than
the choice of legume variety for the cultivation effects [43]. Pea varieties differ considerably in
