The article presents the results of two years of research on the use of plant waste (wheat straw, sunflower husks, hemp stalks, and sawdust) as a substrate for growing oyster mushroom fruiting bodies, followed by the use of the spent substrate as part of the soil for growing tomato and cucumber seedlings. The composite substrate consisting of a mixture of straw and husks increased the growth rate of the mycelium and the yield of oyster mushrooms. The appearance of fruiting bodies was observed 5-7 days earlier than on substrates of a different composition. The biological efficiency of using such a substrate with mycelium was 27%. The processed mushroom substrate in the composition of soil (OGP) 80% + peat – 10% + river sand – 10% proved to be optimal for growing seedlings of the Yamal tomato variety and the Teshcha cucumber. The germination rate, the speed of seedling growth, the thinning of the crops, and the yield of seedlings in this variant were the best.
