    Evaluarea indicilor de calitate a fitomasei energetice de Dactylis glomerata L. şi Festuca pratensis Huds
    (CEP USM, 2024-10-07) Ţîţei, Victor; Ababii, Alexei; Blaj Vasile; Doroftei, Veaceaslav; Gadibadi, Mihai; Andreoiu, Andreea; Marușca, Teodor; Gudima, Andei; Tod, Monica; Daraduda, Nicolae
    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%.

    Evaluarea producţiei şi calităţii speciei Alopecurus pratensis în condiţiile specifice Depresiunii Başovului
    (CEP USM, 2024-10-07) Tod, Monica; Bălan, Mironela; Zevedei, Paul; Andreoiu, Andreea
    The study was carried out based on the experience of a comparative culture, which is composed of 11 genotypes of Alopecurus pratensis and presents the production capacity and the quality of the fodder obtained under the specific conditions of the Brașov Depression in the year 2023. The results obtained showed that the production of dry matter of the species was obtained between 8.68 and 10.27 tons per hectare. The fodder quality of the species was good, having an average content of crude protein (CB) of 13.8%, in crude fiber (CF) of 32.6%, and digestibility coefficients (DMD, DOM) varied between 57.4 and 60.5%. Based on the results obtained, it can be concluded that the species Alopecurus pratensis in culture has a high potential, a minimum of three harvests can be made in an agricultural year, at first cut the highest production of dry matter is obtained, representing 45% of the total production, and depending on the phenophase of the vegetation at harvest, the fodder obtained can ensure a high quality.
