Yield of mixtures and their components depending on sowing rate [35]
2.3.2. Soil
The yields of legume-cereal mixtures largely depend on the soil type. On good soils, almost
all plant species can be grown and yield very well, because there are no significant restrictions
in terms of the selection of individual species. Mixtures may, however, be successfully grown
on the worse soils by one quality class than their components grown in sole crops. As a result
of differentiated plant growth and development rhythms of individual components, the plants
better use of habitat conditions in less favorable soil conditions, as well as in the fields with
differentiated soil, deficient water conditions, different forecrops or levels of soil culture [50].
Mixtures of peas with wheat and barley yielded best on Gleyic Phaeozem, Fluvic Cambisol
and Haplic Luviosol. The poorest soils are based on sand [51]. On lighter soils (good rye
complex), the most efficient mixture was spring triticale with yellow lupine, while slightly
worse-triticale with pea and triticale with vetch. Mixtures of oats with yellow lupine and oats
with pea also yielded well in such soil conditions [45, 52]. On good soil (good wheat complex),
there is no need to cultivate spring cereals with lupines (white, yellow or blue), because the
level of their yield has been found not significantly higher than on poorer soils. They are a
valuable component, for cultivation on medium and light soils.
