Abstract:
The research and exploitation of the agrobiological potential of the local Fabaceae species that are adapted to the soil
and climatic conditions becomes more and more relevant. The annual leguminous species Lathyrus sativus, Pisum
sativum arvense, Trigonella foenum-graecum, Vicia hirsuta and Vicia sativa grown in monoculture in an experimental
sector in the NBGI Chişinău, served as objects of study. The research results revealed that the dry matter of the
harvested whole plants contained 142-251 g/kg CP, 251-377 g/kg CF, 89-124 g/kg ash, 254-390 g/kg ADF, 416-598
g/kg NDF, 34-65 g/kg ADL, 220-327 g/kg Cel, 155-206 g/kg HC, 64-160 g/kg TSS with nutritive and energy value
62.2-85.1% DMD, 59.3-80.1% DOM, RFV=91-151, 9.51-11.09 MJ/kg ME and 5.53-7.10 MJ/kg NEl. The biochemical
composition, nutritive and energy value of the prepared hay: 131-164 g/kg CP, 244-418 g/kg CF, 50-135 g/kg ash, 294-
436 g/kg ADF, 475-645 g/kg NDF, 36-76 g/kg ADL, 258-360 g/kg Cel, 165-209 g/kg HC, 6-70 g/kg TSS, 53.1-74.5%
DMD, 51.6-68.4% DOM, RFV=85-129, 9.00-10.63 MJ/kg ME and 5.00-6.65 MJ/kg NEl. The green mass substrates for
anaerobic digestion have C/N= 11.8-22.3, with biochemical methane potential 305-378 l/kg. The biomass harvested
from the studied annual leguminous species can be used as fodder for animals or as co-substrates in biogas plants for
the production of biomethane as a renewable energy source.
