In the zone of the Western Forest-Steppe, atypical weather conditions, in particular warming, unevenness of precipitation during the growing season affect the phytocenotic properties of legumes, grasses and their grass mixtures as well as the processes of forming the productivity of meadow agrophytocenoses. Complete mineral fertilization with additional foliar fertilization with microfertilizers allows to preserve their constant productivity over time. The conducted studies showed that the treatment of fodder biomass with microfertilizer Rokohumin on the background of N60P60K90 fertilizer had a positive effect on the productivity of pasture and hay legume-grass stands, regardless of the species composition. However, in 2016-2020, on average, the legume-grass mixture of sedge, reed sedge, perennial fenugreek, hornwort, meadow clover and creeping clover ensured the collection of 9.3 t/ha of dry matter during three-times mowing. The annual productivity of the pastures of this species composition for five years of operation was 6.7 t/ha of fodder units with the highest level of profitability of 205.2% on the biological and mineral background of fertilizer versus 42.7% by haying. Preservation of the highest saturation of agrophytocenosis with legumes (17.9 and 19.6 %) in the fifth year of life is characteristic of pasture grasses, in particular of reed sedge, perennial fenugreek, horned sedge, meadow and creeping clover.
