Abstract. The purpose of the research was to determine the effect of different fertilizers on productivity and quality indicators of gramineous grass mixtures with Lolium multiflorum. The experiment was performed in 2014–2017 in the Republic of Tatarstan on typical grey forest soils. We studied the effect of two factors: the type of grass mixture (factor A) – Lolium multiflorum (control), Lolium multiflorum + Festuca pratensis, Lolium multiflorum + Bromus inermis; fertilizer (factor B) – control (without fertilizers); N48P36K20 for the planned yield of green mass of 35 t/ha; Izagri NPK, 6 L/ha; Biocomposite Correct, 6 L/ha. The highest yield of green and dry mass (30.7 t/ha and 7.37 t/ha respectively) was obtsined in the case of cultivation of Lolium multiflorum with Bromus inermis with N48P36K20. It was more than in the control case (without fertilizer) by 54.8% and 68.6% respectively. The yield of dry weight of grass mixture with Festuca pratensis exceeded the value of this indicator in monoculture by 0.36 t/ha, but was lower than in the variant with Lolium multiflorum + Bromus inermis grass mixture by 1.08 t/ha. The application of Biocomposite Correct increased the dry weight of Lolium multiflorum by 26.4%, the mixture of Lolium multiflorum and Festuca pratensis – by 28.7%, and the mixture of Lolium multiflorum and Bromus inermis – by 29.3%. In the case of Biocomposite Correct the content of digestible protein in absolutely dry weight of the mixture of Lolium multiflorum with Festuca pratensis amounted to 10.8%. The amount of sugar was 11.2%. The profitability of the production of feed mixtures from Lolium multiflorum and Festuca pratensis laced with Biocomposite Correct fertilizer was higher (37.8%) than in a similar case with a single-species Lolium multiflorum croo (28.6%) and in the case with the admixture of Bromus inermis (35.5%). However, it was the highest in the case with N48P36K20 (53.9%).
