This study was conducted to investigate the effect of seeding dates on grassland productivity and botanical composition in oversown hilly pasture located in Pyeongchang of South Korea. Four treatment groups were established based on the seeding dates of grass mixture: T1, August 13; T2, August 27; T3, September 10; and T4, September 24. Evaluation of seasonal changes in grass botanical composition revealed the highest ratios of grass in T1 and T2 (81-100% grass) and the lowest in T4 (46-90 % grass). In the plant length, the first harvest time was longer than other cutting times and last harvest time was the lowest. The total dry matter yield of grass was highest in T2 (9,042 kg ha-¹) and T1 (8,845 kg ha-¹) and lowest in T4 (5,086 kg ha-¹). The findings of the present study suggest that seeding by late August provide the most desirable results for vegetation and grassland productivity in oversown hilly pasture, Pyeongchang of South Korea..
