We studied the quality of the biomass (straw) of perinnal grass seed crop: Festuca arundinacea, Festuca pratensis, Festuca rubra, Pennisetum alopecuroides, Phleum pretense. The biochemical composi-tion of straw: 36-83 g/kg CP, 400-555 g/kg CF, 46-98 g/kg CA, 647-918 g/kg NDF, 424-604 g/kg ADF, 53-86 g/kg ADL, 371-518 g/kg Cel, 223-314g/kg HC, with nutritive and energy value 10.3-39.3 % DMD, 8.8-36.2 % ODM, 7.08-9.14 MJ/kg ME and 3.10-5.45 MJ/kg NEl. We found that the straw substrates for anaerobic digestion, have C/N=37-92 and biochemical methane potential 254-313 l/kg ODM. The theore-tical ethanol yield from structural carbohydrates averaged 432-605 L/t.
