An on-farm experiment was conducted over six seasons, from March 1999 until December 2001, around Sinana Agricultural Research Center to evaluate six seeding rates of oat/vetch mixtures (80/30, 60/7.5, 40/15, 20/22.5, 80/0 [sole oat] and 0/30 [sole vetch] (kg/ha) for forage yield. Effect of the oat/vetch seeding rates on the yields of the subsequent crop was also studies in a barley-based double cropping system. The results indicate that dry matter (DM) yield increased with increasing oats seed rate in the mixture but decreased with increasing vetch seed rate. The highest mean DM yield (7.0 t/ha) was recorded in the 80/30 (kg/ha) oat/vetch seeding rate followed by the sole oat (6.5 t/ha DM). However, DM yield difference in the 60/7.5, 40/15, and 20/22.5 (kg/ha) oat/vetch seeding rates was no significant (p0.05). However, more information on the effect of seeding rates on growing good quality oat-vetch mixture is required.
