Abstract. Based on the results of the field experiment in the Tver Region, it had presented the data of the growth, development, and productivity of legume-grass mixtures of haymaking type of the fifth year of use on the drained lands of the Nonblack Soil Zone. The legume-grass mixtures provided stable productivity for the fifth year of use. This was due to the inclusion in the mixture a long-term bastard lucern. The introduction into the mixed forage agrophytocenoses of two interchangeable legumes (giant clover and bastard lucern) allowed to reduce the need for nitrogen by 50 % or more, to increase the dry matter yield by 2…3 t/ha, to prolong the forage productivity of the herbage and the nutritional value of the feed. The studied fodder agrocenoses included: VIK 7, Mars, Dymkovskii varieties of giant clover, Nakhodka varietу of bastard lucern, VIK 9 genotype of meadow catmint, Sakharovskaya varietу of meadow fescue grass, Khlynovskaya genotype of orchard grass. During the research, the crops were characterized by the stable dry weight productivity up to 6.9 t/ha and sustainable adaptability to the growing conditions. For the introduction of fodder herbage mixtures in production with haymaking technology, it was not recommended to use Iygeva variety of bastard clover and VIK 90 genotype of festulolium because they could not compete with fast-growing red clover and bastard lucern. As a result of research, the most highly productive and highly nutritious of species composition of complex legume-grass mixtures of new generation varieties were identified. These grass mixtures were based on of varieties of red clover of different ripening groups (VIC 7, Mars, Dymkovsky, Vityaz) used in a mixture with Nakhodka variety of bastard lucern and grass components (VIK 9 genotype of meadow catmint, Sakharovskaya varietу of meadow fescue grass, Khlynovskaya genotype of orchard grass). This will ensure the productive longevity of forage lands and increase the yield of high-protein balanced fodder got from drained land.
