In order for Paldanghomil (winter rye) to be investigated if its grain yield is able to be produced after clipping just before winter season for forage utilization this experiment was carried out under the four sowing dates of four locations in Korea (Chunchon, Suwon, Hwasung and Chongju). In rye clipping plot earlier sowing showed taller plant height, more number of tillers/sqm and higher forage yield before winter season, indicating the highest forage yield (1803 Kg/10a)in Chunchon by sowing of September 11.1911 Forage yield of rye before winter season was mainly influenced by plant height and number of tillers/sqm, showing more effect of plant height. Rye plants were more or less affected by winter damages, late heading and short culm by clipping before winter season. Analysis of variance indicated that only number of spikes/sqm among grain yield components showed the high significance according to the clipping method, and that there showed little variation for other yield components due to the sowing date and clipping plot, indicating the difference of 46Kg/10a. This was resulted from short culm and severe winter damages caused by clipping before winter season. Of the grain yield components, number of spikes/sqm was greatly influenced for grain yield by analysis of stepwise regression. Therefore, grain yield of rye was able to produce after forage utilization before winter season due to the appropriate crop and soil managements, by resulting from the little variation in grain yield between clipping or non-clipping plots and from the higher grain yield by the early so
