This research was conducted to determine the productivity of switchgrass - Panicum virgatum and common millet - Panicum miliaceum, grown in monoculture in the experimental plot of the NBGI Chişinău. It was determined that the dry matter yield and its biochemical composition varied among the Panicum species: 8.2-14.1 kg/m2 with 61-132/kg CP, 352- 419 g/kg CF, 82-101 g/kg ash, 372-433 g/kg ADF, 608-692 g/kg NDF, 39-59 g/kg ADL, 124-127 g/kg TSS, 333-381 g/kg Cel, 236-259 g/kg HC and the nutritive and energy values of the fresh mass fodder reached 55.2-59.9 % DDM, 9.04-9.73 MJ/kg ME and 5.05-5.75 MJ/kg NEl. The hay prepared from the studied Panicum species contained 56-132 g/kg CP, 79-104 g/kg ash, 348-384 g/kg Cel, 243-272 g/kg HC with 54.5-58.8 % DDM, 8.94-9.57 MJ/kg ME and 4.96-5.59 MJ/kg NEl. The prepared silages had pH index = 4.06-4.14, 30.6-32.5 g/kg organic acids with 88.0-93.5% lactic acid. We found that the biochemical methane potential of the studied substrates varied from 302 to 364 l/kg ODM. Panicum virgatum and Panicum miliaceum may be used as forages for livestock and as feedstock for renewable energy production in Moldova.
