Abstract Results of researches about mineral fertilizers and inoculation influence on the growth and plants development of Common, Transcaucasian and Hungarian sainfoin for growing on green feed are shown. The experimental part of the work was done during 2016-2018. Experimental plots were laid on typical low-humus coarsesilty, light-loamy in terms of mechanical composition chernozems, soils characterized by a high content of gross and mobile forms of nutrients. Weather conditions during the years of research were not sufficiently favorable for perennial grasses growing, only 2016 had precipitation close to normal, but increased temperature of the air did not contribute to the high yield of perennial grasses. It was found that the high levels of organic raw substances in the feed during the period of full flowering has herbages of Hungarian sainfoin variety Smaragd, and the content of free-nitrogen extract substances (FNE) had the lowest indicators. With mineral fertilizers introduction was obtained a tendency of increasing organic substances content in the feed, regardless to sainfoin type. Mineral elements content in the feed significantly depended on sainfoin type and mineral fertilizers application. With introduction of mineral fertilizers, the content of all certain mineral elements increased regardless to the type of sainfoin.
