The agro-energy efficiency of using new varieties of creeping clover (Lugovik), meadow clover (Veteran) and alfalfa changeable (Agnia) in comparison with previously zoned varieties of these species (respectively - VIC 70, Tetraploid VIC and Pasture 88) is determined on the basis of the results on productivity and total anthropogenic costs obtained in the field experience based on the dry-fall type of pastures occupying 92% in the Central region of the European part of Russia. The assessment of agro-energy efficiency was determined according to the methods approved by the Russian Academy of agricultural Sciences. Taking into account a set of indicators (productivity of improved land for the production of exchange energy in GJ / ha and products produced in MJ per 1 GJ, reducing total anthropogenic costs in GJ/ha and increasing their payback), the high efficiency of new varieties is established and the principle of changing varieties in meadow forage production is scientifically justified. At the same time, the effectiveness of previously zoned varieties of leguminous grasses has also been confirmed, which allows increasing their seed production in the regions due to the high demand not only for field, but also for meadow grass.
