Fodder production determines not only the state of animal husbandry, but greatly influences on development of plant-growing; solves the agricultural concerns and nature use; increases stability of agro systems; promotes restoring of soil fertility. That’s why perennial leguminous grasses are of great importance and significance. The plants are valuable for biologization of agriculture and farming. A vast number of concerns in plant-growing, agriculture and animal husbandry could be solved due to development of new productive and valuable fodder from the varieties of alfalfa and sainfoil. The article discusses productivity and quality of fodder of alfalfa varieties ‘Lyutsiya’(2010), ‘Selyanka’(2013) and sainfoil varieties ‘Veles’(2010), ‘Sudar’(2015), introduced into the State Register. The long-term researches determined that the alfalfa and sainfoil varieties, selected and approved for use, possess better productivity of green mass and dry matter of than of the standard varieties. The studied alfalfa and sainfoil varieties produced fodder units on 8,6%-10,2% more than the standard ones in the first harvesting and on 14,4%-20,3% more in the second harvesting. As for the digestible protein the alfalfa and sainfoil varieties produced it on 8,0% – 9,8% more than the standard ones in the first harvesting and on 12,5% – 18,8 % more in the second harvesting. The new alfalfa and sainfoil varieties possess the same amount of digestible protein per fodder unit as the standard variety. The amount of fodder units of sainfoil varieties exceeded the standard ones on 10,0% – 11,3%, the amount of digestible protein exceeded the standard ones on 14,4% – 19,6%, but the amount of digestible protein per fodder unit was the same as of the standard variety.
