Field studies were conducted to test the effect of four seed rates of spring vetch cv. Kwarta grown in mixtures (by seed weight) with covered oat cv. Dukat (100 + 0, 50+130, 40 + 150, and 30 + 170 kg/ha, respectively) on vetch yield, over a 3-year period (1996-1998). Total yield of the mixtures (oat + vetch) was systematically increased by decreasing seed rates of vetch. Consequently, the highest yield of the mixtures (2.88 t/ha) was obtained from the combination using the lowest seed rate for vetch (30 kg/ha) and the highest seed rate for oat (170 kg/ha). Yield of vetch seeds was conversely related to the total yield of the mixtures. It was also affected by seed rates of vetch and climatic conditions during growing seasons. The highest yields of vetch seeds and vetch seed protein were obtained from vetch grown in pure sowing (3.86 dt/ha and 121 kg/ha, respectively). With increasing contribution of oat to the vetch:oat mixtures, these yields decreased linearly.
