Leaf biomass provides theoretical energy at the level of 18–45 GJ/ha, which is transformed into biogas, the amount of which is 895–2138 m3/ha and methane – 452–1080 m3/ha (1m3=2kW). It was established that rare perennial grasses are able to provide biomass at the level of 4.5–18.0 t/ha or 2.3–6.3 t/ha in terms of dry matter, depending on the type of grasses and the fertilization system. Less common perennial grasses provide an output from one hectare of theoretical energy of 13.66–52.77 GJ/ha, which is transformed into biogas, the amount of which is 651–2513 m3/ha and methane – 329–1269 m3/ha (1m3= 2kW) . It was established that the fertilization system contributed to the growth of the yield of renewable vegetative biomass by 8–53%. With the use of the complex mineral fertilizer Polifoska 8, the increase in yield was 8–16%, with the use of Krompaks at the level of 26–53%, depending on the variety. The raw yak obtained contains radiocesium 29.0.40 Bq/kg and strontium 0.00–20.52 Bq/kg. The introduction of rare perennial grasses into production will allow the use of overmoistened soils and fields where long-term flooding is observed.
