The agrobiological features, the quality of the green mass and haylage from the local ecotype of Glycyrrhiza glabra and Onobrychis arenaria have been the subject of a recent study. It has been found that the dry matter of harvested green mass of the studied crops contained 162-167 g/kg CP, 302-307 g/kg CF, 88-100g/kg CA, 467-471 g/kg NDF, 317-321 g/kg ADF, 48-54 g/kg ADL, 267-269 g/kg Cel, 150 g/kg HC, 100-103 g/kg TSS, 64.7-67.7 % DDM, 54.3- 59.9 % ODM, RFV= 125-127, 10.23-10.28 MJ/kg ME and 6.34-6.56 MJ/kg NEl. The biochemical composition of the dry matter of the haylage and its nutritive value: 155-184 g/kg CP, 267-301 g/kg CF, 114-123 g/kg CA, 429-550 g/kg NDF, 299.333 g/kg ADF, 47-50 g/kg ADL, 249-288 g/kg Cel, 130-187 g/kg HC, 79-91 g/kg TSS, 62.4-67.8 % DDM, 53.6-54.0 % ODM, RFV= 113-142, 10.20-10.57 MJ/kg ME and 6.20-6.59 MJ/kg Nel. We found that the studied substrates for anaerobic digestion have C/N=16.54-19.85, optimal amount of lignin and hemicelluloses, the biochemical methane potential varied from 283 to 301 l/kg ODM. The studied ecotype had optimal quality as fodder for livestock and as substrate for biomethane production.
