According to the mean of 2 years, the different mixture ratios and row spacings had a statistically significant effect on all of the properties. At the end of the research, among the different mixture ratios and row spacing interactions, the highest green herbage yield (33.4 t ha -1 ), hay yield (7.5 t ha -1 ), lowest neutral detergent fiber (52.2%), and crude ash (7.8%) rates were obtained from the 60%HV+40%AR mixture and 30-cm row spacing interaction. The highest crude protein (CP) rate (17%), CP yield (1156 kg ha -1 ) and ADF (39.5%) ratios were obtained from the 80%HV+20%AR mixture and 30-cm row spacing interaction. The highest RFV value (107) was obtained from the 80%HV+20%AR mixture and 20-cm row spacing interaction. These results show that increasing the HV ratio in the mixture has positive effects on the yield and quality, whereas raising the row spacing has adverse effects on the forage values. Therefore, 80%HV+20%AR or 60%HV+40%AR with a 30-cm row spacing interaction can be suggested for forage production in an HV and AR intercropping system.
