Summary. Researches were carried out to study the productivity of mixes of forage crops used in postcut and stubbly crops for an increase in high quality forage yield during summer-autumn period per one hectare of sown area. The scheme of three-factor experiment included the following variants. Factor A was forage crops: vetch with oats; spring rape; Sudan grass; Sudan grass with soybean. Factor B was sowing date: the first one was after harvesting of winter rye for green fodder since the end of the second and till the beginning of the third decade of May; the second one was after harvesting of winter rye for green fodder since the end of the first and till the beginning of the second decade of June; the third sowing time was after harvesting of winter rye for grain. Factor C was fertilizers: without fertilizers (the control); N₁₆P₁₆K₁₆, N₅₆P₁₆K₁₆. Field experiment was carried out in 2011-2014 on leached black soil in Republic of Mordovia. The use of intermediate forage crops for green mass after winter rye increases efficiency of 1 hectare of an arable land by 1.0…7.31 tons of dry matter or by 0.94…5.08 tons of fodder units. The maximum productivity (24.2 t/ha) of plant green mass was provided by mixed crops of Sudan grass with soybean against the background of full mineral fertilizer at the dose of N₅₆P₁₆K₁₆ when sowing at the end of the second – the beginning of the third decade of May. In the variant with spring rape depending on sowing time the productivity was 9.5…18.3 t/ha of green mass and from 1.4 to 3.84 t/ha of dry matter.

Keywords: winter rye, vetch-oats, Sudan grass, soybean, sowing dates, mineral fertilizers, productivity.
