Objectives of the present study were to determine the variations in hay yield and hay quality of different Hungarian vetch genotypes. Experiments were conducted for three years in 2014-2015 and 2016 in randomized blocks design with three replications. A total of 5 Hungarian vetch cultivars and 5 local Hungarian vetch were used as the plant material of the experiments. Genotypes on hay yield and hay quality of Hungarian vetch were found to be highly significant (P<0.01) and the years were on yield and chemical composition were found to be highly significant (P<0.01). Present finding revealed that that plant height of the Hungarian vetch genotypes varied between 90.16 cm and 105.20 cm, green herbage yield between 1429.58 kg/da and 1936.22 kg/da, hay yield between 298.28 kg/da and 380.66 kg/da, crude protein yield between 50.81 kg/da and 77.06 kg/da, crude protein ratios between 15.50% and 20.89%, crude ash ratios between 7.32% and 8.75%, acid detergent fiber (ADF) ratios between 34.32% and 40.74%, neutral detergent fiber (NDF) ratios between 46.36% and 50.01%, dry matter digestibility (DMD) ratios between 57.17% and 62.16%, dry matter intake (DMI) ratios between 2.41% and 2.60% and relative feed value (RFV) between 106.73 and 124.65 depending on the cultivars. Local Hungarian vetch genotypes were found to be prominent with yield and crude protein ratios and they will be use to breeding program.
