- Abstract
This research was aimed at evaluating some agrobiological peculiarities and the biochemical composition of the harvested fresh mass and hay prepared from a local ecotype of crown vetch, Coronilla varia, grown in monoculture in an experimental field of the National Botanical Garden (Institute), Chişinău, Republic of Moldova. It has been found that the studied local ecotype of crown vetch can be mowed 2-3 times per season starting with the second year of life. The dry matter of harvested plants contains 157-167 g/kg CP, 85-110 g/kg ash, 292-342 g/kg CF, 303-353 g/kg ADF, 450-519 g/kg NDF, 51-58 g/kg ADL; the fodder value is 61.42-65.30 % DMD, RFV=110-135, 9.95-10.53 MJ/kg ME and 5.97-6.54 MJ/kg NEl. Crown vetch hay has a pleasant smell and contains 160 g/kg CP, 90 g/kg ash, 340 g/kg CF, 349 g/kg ADF, 507 g/kg NDF, 56 g/kg ADL, 61.21 % DMD, RFV=113, 9.93 MJ/kg ME and 6.02 MJ/kg NEl. The substrate of crown vetch fresh mass used for anaerobic digestion is characterized by an optimal carbon-nitrogen ratio - C/N = 18.5-20.2, contains 147-166 g/kg hemicellulose, 51-58 g/kg lignin and the biochemical biomethane potential reaches 281-286 l/kg ODM. Coronilla varia can be used to re-cultivate permanent grasslands and to establish temporary grasslands in order to prevent soil erosion, in monoculture or associated with other grasses, and the harvested mass can be used as natural feed or hay for ruminants, or as a substrate for the production of biomethane and renewable energy.
