The duration of the growing season was determined for the following plants: reed canary grass (Cynodon dactylon and Setaria viridis), which is 167-190 days in the conditions of the zone; reed moliinia – 150-167 days; giant miscanthus – 130-156 days, depending on vegetation conditions. Based on a comprehensive assessment of uncommon perennial grasses, the most suitable species for green energy needs have been identified: Miscanthus giganteus, Phragmites australis, and Leymus cinereus, which provide a yield of vegetative mass per hectare of 7.5-20.9 t/ha (2.8-9.5 t/ha of dry mass), theoretical energy at the level of 12.18-70.61 GJ/ha, which is converted into biogas 580-2983 m3/ha and methane 293-1698 m3/ha, depending on the fertilization system. It has been determined that an optimized fertilization system involving the application of N90+30Р60К90 + SuperAgro NPK(8:24:24+S3) contributed to plant development by 8-23%, an increase in the yield of vegetative plant mass by 31-50%, and energy yield per hectare by 33-61%; the application of N90+30 Р60К90++ Smart Grow 18-18-18 contributed to plant development by 5-13%, 11-32%, and 17-31%, respectively, compared to the control, depending on the type of grass. Raw materials obtained from rare perennial grasses were characterized by levels of contamination with radiocaesium of 8.6–15.20 Bq/kg and strontium of 8.00–26.5 Bq/kg.
