Optimal time for sowing mixed summer crops for green fodder

In most of the territory of the Russian Federation in grain-growing areas, the second half of the growing season (July-August) is more favorable in terms of precipitation and positive temperatures, and by October, summer mixed crops of legumes and cereals can form a fairly large number of green mass. The inclusion of mixed legumes and cereals with different linear growth rates makes it possible to create multi-tiered crops: the lower tier was occupied by lupine and paiza, the upper tier-beans, vetch and peas. This arrangement of plants allows crops to use the energy of sunlight more efficiently and prevent the evaporation of moisture from the soil, especially during the summer sowing period. Quality assessment of the yield of green mass of summer intercropping legume-cereal crop output chromoproteins units per 1 ha showed that late summer time summer mixed sowing has the advantages of not only protein, but also carbohydrates. The maximum collection of protein and forage protein units was obtained in the summer mixed sowing of narrow-leaved lupine, forage beans, spring vetch, forage peas and payza. Therefore, research on obtaining high-protein green feed for herbivorous farm animals in the late autumn period in the Kaliningrad region is promising and requires careful study.
