The paper presents the results of using festulolium herbage for fodder purposes in single-species sowing and in mixture with meadow clover in the forest-steppe of Western Siberia. The aim of the research is to develop methods of cultivation of single-species and mixed crops of meadow clover and festulolium in the conditions of the forest-steppe of Western Siberia. We found that climatic conditions of the zone are favorable for cultivation of festulolium. Preservation of plants on average for two crops in time amounted to 97% (V = 1%), winter hardiness – 88% (V = 2%), survival rate – 85% (V = 1%). Joint sowing of festulolium with clover without the use of mineral nitrogen yields 5–13% more (1.17–3.09 t/ha of green mass) than single-species crops. At the same time, gross yield per hectare of fodder units increased by 17% and amounted to 4.8–5.1 tons, digestible protein – by 16–85% to 507–666 kg. Application of mineral nitrogen had a positive effect on increasing the yield of single-species crops by 26–28% (up to 29.00–31.69 t/ha), mixtures – by 22–23% of green mass (up to 31.99 t/ha) due to increasing the shoot weight of meadow clover by 9–35% (r = 0.28...0.71) and increasing its share in the yield up to 42–52%. The advantage has a variant of joint sowing with the alternation of three rows of clover and one row of festulolium at a row spacing of 15 cm. The profitability level was 339%, net income for three years of use 145,595 rubles/ha, energy yield with yield – 219.2 GJ/ha, KEE = 3.7
