This study was carried on comparison of forage yields and growth of cropping system as forage (winter & summer) in Cheonan 2015~2016. The species of forage crop used were Barley (cv. Youngyang), Sorghum (cv. SX17), Proso millet (domestic) and Japanese millet (cv. Jeju). Plant height is the lowest when harvested in lough stage than in the harvests of all summer crops. The dry matter yield of lough stage was 1,343 kg/10a in barley. Looking at the dry matter according to cropping systems, the sorghum was higher at 10,018 kg when harvested at the lough stage than at the harvest. Dry matter of Proso millet and Japanese millet also had higher at the lough stage than at other harvest times. ADF content of sorghum was lower than that of harvesting, but Proso millet and Japanese millet showed higher ADF content in lough stage. The NDF content of the three crops was higher than that of the harvests, and crude protein content was higher in harvest than that of at lough stage. Total production of crude protein against dry matter yield was about 761 kg when sorghum was harvested at lough stage. There was no difference in the content of TDN among three crops according to harvesting time.
