    We studied the quality indices of the energy phytomass from perennial grass Dactylis glomerata and Festuca pratensis, collected from the experimental field of the National Botanical Garden (Institute) MSU, Chişinău. The quality indices of green mass substrates for anaerobic digestion: 92-98 g/kg CP, 359-389 g/kg CF, 76-80 g/kg CA, 648-682 g/kg NDF, 380-412 g/kg ADF, 33-41 g/kg ADL, 347-371 g/kg Cel, 269-270g/kg HC, with C/N=32.74-34.72 and biochemical methane potential 337-350 l/kg ODM. The quality indices of phytomass (straw) substrates: 771-799 g/kg NDF, 478-484 g/kg ADF, 54-65 g/kg ADL, 419-424 g/kg Cel, 293- 315g/kg HC and theoretical ethanol yield from structural carbohydrates averaged 522-533 L/t. The quality indices of solid biofuel–pellets: 8.01-9.03% ash, 18.10-18.44 MJ/kg GCV, 16.73-17.07 MJ/kg NCV with bulk density 595-652 kg/m3 and durability 93-96%.
