Abstract The results of the research on economic and bioenergetic evaluation of different types of sainfoin growing depending on fertilizer, grass mowing height, seed inoculation and years of use were presented. Sainfoin is one of the most productive legumes with a high protein content, the green mass of which exceeds both cereals and some perennial legumes by the protein content. However, despite the significant advantages of sainfoin, the areas under this crop remain insignificant, especially in the Forest-Steppe zone. One of the reasons for this state is the undeveloped zonal technology of growing of different varieties of sainfoin with their economic and energy evaluation. Research methodology. Experimental studies were conducted during 2016–2018 at the research site of the SS of NULES of Ukraine “Agronomic Research Station” located in Pshenychne village of Vasylkiv district of Kyiv region. Scheme of the experiment: Factor A. Varieties of sainfoin (Common (Ametyst Donetsky variety); Transcaucasian (Adam variety); Hungarian (Smaragd variety). Factor B. Fertilizers, inoculation (without fertilizers and inoculation; N45Р60К90 + seeds inoculation with rhizotorphine; Р60К90 + seeds inoculation with rhizotorphine). Factor C. The height of grass mowing (5, 10, 15 cm). Method of sowing – by row, spring coverless. Rhizotorphine was used for inoculation. Conclusions. It was found that the highest conditionally net profit and the lowest prime cost of fodder unit and crude protein were obtained under common sainfoin growing, economic indicators of growing of Transcaucasian sainfoin and Hungarian sainfoin were much lower than the aforementioned. The highest energy efficiency coefficient and the lowest energy costs for growing of 1 ton of fodder units were obtained on the sowings of common sainfoin of Ametyst Donetsky variety.
