ABSTRACT. The research was carried out on the territory of c. Tsenzhiv of Yamnytsya territorial community of Ivano-Frankivsk region on sod-podzolic degraded soils according to generally accepted research methods. The productivity of miscanthus and switchgrass depends on the biometric indicators of plants, namely the height of plants and the number of stems. Correct models of miscanthus and switchgrass productivity are calculated depending on the dose of sewage sludge. For miscanthus, the correlation coefficient r = 0.952 and for switchgrass r = 0.951, which indicates a high linear relationship between plant height, number of stems and productivity. Dry matter yield in grass energy crops varies according to fertilizer application. The productivity of the agrophytocenosis of miscanthus is much higher than that of switchgrass. With the addition of sewage sludge at a dose of 40 t/ha, the dry matter yield under the same growing conditions in the agrophytocenosis of miscanthus is 12.2 t/ha, or 3.3 t/ha higher than the productivity of agrophytocenosis switchgrass. Significant impact on yield is the use of composts based on SS + straw (3: 1)) - 30 t/ha + N30K55, which provides the highest productivity of miscanthus - 13.0 t/ha, and switchgrass - 9.6 t/ha. To obtain stable biomass productivity of grass energy crops (miscanthus and switchgrass), it is advisable to use compost of sewage sludge and straw in a ratio of 3: 1 at a dose of 30 t/ha. Thus, two important problems are partially solved - increasing the productivity of energy crops and utilization of municipal waste (sewage sludge).
