Abstract: Intercropping productivity under conventional farming system was carried out in the experimental field of The Trakya Agricultural Research Institute (TTAE) in Edirne province in 2012-2015 growing seasons with 3 replications on randomized complete block design. The experiment consisted of mainly 7 entries for yield components - i.e., three pure stands Hungarian vetch (HV), oat (O) and annual rye grass (ARG) and four different mixtures (66% HV+34% O, 34% HV+66% O, 66% HV+34% ARG, 34% HV+66% ARG) as follow. Seven traits including plant height (PH), stem diameter (SD), leaf/stem ratio (LSR), legume ratio in botanic composition (LRBC), legume fresh forage yield (LFFY), total fresh forage yield (TFFY), total dry forage yield (TDFY), plant height (PH), stem diameter (SD) and leaf/stem ratio (LSR) were measured on 10 random (vying plant) points per plot. Legume ratio in botanic composition (LRBC), legume fresh forage yield (LFFY), total fresh forage yield (TFFY), total dry forage yield (TDFY) were recorded at each plot. In mixtures of Hungarian vetch with annual rye grass, average forage yield (21.86 t ha-1) was lower by 32% than (28.87 t ha-1) that in mixtures of Hungarian vetch with oat average yield. Consequently all of the investigated parameters in the present study, 60% or 40% HV mixture with oat combination, can be recommended for high yield forage production.
