agrophytocenoses (Trifolium pratense and Medicago sativa sown with the
addition of Bromus inermis, Lolium multiflorum, Festuca rubra),
highlighted their economic and energy advantages over cereal grasses. The
article presents the results of the study of the influence of grass mixtures
on the main indicators of the efficiency of growing sowing phytocenoses
during haymaking in the Carpathians on dark grey soil. Growing
agrophytocenoses without mineral fertilizers ensures the maintenance of
370–520 € ha–1 of net profit, with the profitability of 151–187%, the cost
of 1 ton of feed units – 56.7–66.7 €, bioenergy coefficient – 2.5–2.9,
energy efficiency ratio – 5.8–6.5 and energy consumption per 1 ton of feed
units – 4.0–4.7 GJ. The cultivation of alfalfa-cereal grasses is ensured on
dark-wet soil with three years of use of the best indicators of economic
and energy efficiency. It was found that on both experimental bean–cereal
grasses the highest efficiency is maintained when P60K60 is applied in
combination with inoculation of seeds of bean strains of nodule bacteria
