This experiment aimed to investigate the green  matter production  of  three  different  combinations  of  Oat and  legumes:  (a) oat (aveng sativa L) var.kent  + Common  vetch (vicia sativa),(b) Oat + Field pea (Pisum satiyum var. arvense and (c) Oat + Garden pea  (Pisum satiyum L) at four  levels of Nitrogen  (N0 N 40 N 70 and N100. One half of the N was applied as basal dose at the time of land preparation  and remaining one half  was top dressed after the first cut. Plants were harvested three times during February to April at approximately 35 days interval. The levels of nitrogen significantly influenced (P<O.OI) on the green matter production of all the combinations of oat and legumes.  However, the effects due to the inclusion of three different legumes and Nitrogen x Legumes interaction were not significant. The average GM yield at N 70 (70 kg. N ha-I) was 20.9 MT ha-I i.e. 34 percent higher compared to that of N 0 level (control). An additional amount of N above N70 level had no signifi­ cant effect on the GM production. Oat + c. vetch combination produced highest GM yield of 19.0 MT ha-1compared to that of other combinations, however, differences were not significant.
