The research results for 2018–2020 on the formation of fodder productivity of the yield of the dry mass of different varieties of meadow clover from 1 ha depending on the sowing methods on different backgrounds of fertilizer on typical low-humus chernozems of the Forest-Steppe of Ukraine were presented. On average, for the first three years of growth and use, meadow clover provided productivity of yield of the dry mass of 8.22–9.88 tons from 1 ha, which depended little on sowing methods. Productivity increased by 8–12 % when inoculating seed with nodule bacteria combined with the application of N60P60K90 compared with the variant without fertilizers and only by 4–6 % under separate application of fertilizers (Р60K90 or N60P60K90) or seeds inoculation on the background without fertilizers. The application of N60 on the background of Р60K90 provided the highest payback of 1 kg of fertilizer (6–7 kg of dry mass) among fertilizers. In the first year, sowing under cover of spring barley provided higher productivity by 22–25 %, and in the second and third years, coverless sowing was provided by 7–10 %. The most productive variety was Taifun, which was 0.10–0.66 t/ha of dry mass superior to Lybid and Tina varieties. The factor of fertilization was the most influential in yield of dry mass from 1 ha and the sowing method with a share proportion of 55 % in the first year. Meadow clover annually provided three mowings of fodder biomass with the share of the first mowing of 44–50 %, the second – 32–34 %, and the third – 18–24 %, and the uneven distribution of the yield by mowing by 30–47 %
