A study was carried out in order to find out the bio-mass and seed production on the different sowing times of ten oat cultivars under rainfed condition at RARS Nepalgunj in 1998-99. The result showed significant differences on the biomass and seed yields between the cultivars and sowing dates. All tested sowing times were most sensitive to the green fodder cutting frequencies, bio-mass, 1966 kg per hectare seed grain yield were recorded from 20th November sowing and decreasing trend was noted down in the later sowing periods. The oat cultivar Canadian and Omihi were observed less sensitive to late sowing for the bio-mass prooduction, because of the similar dry matter yields on 20 th November to 5th December sowings. But the seed grain production was the lower at the same sowing times. The cultivar bundel-851 produced the highest biomass and seed grain at 20th November to 5th December sowing period.
