This study was conducted in Cheonan of central region in South Korea to evaluate the forage characteristics of early-maturing Italian ryegrass (IRG) within September, 2021 to June, 2023. The three different varieties of Italian ryegrass were prepared in this study 'Kogreen', 'Kospeed' and 'Kowinearly'. The results of heading date in this study, 'Kogreen' was the earliest in among cultivars and recorded 24th of April, whereas 'Kowinearly' was recorded the latest. In case of plant length parameter, 'Kowinearly' was the highest, in addition lodge tolerance score 'Kowinearly' also superior in whole cultivars. The dry matter yield of 'Kowinearly' was recorded significantly the highest (11,027 kg/ha), in contrast 'Kospeed' was recorded significantly the lowest (8,455 kg/ha). As a result of ADF and NDF content 'Kospeed' was recorded excellent value as compared the other two cultivars. The CP content of this study was excellent in the order of 'Kospeed' > 'Kowinearly' > 'Kogreen'. In case of the monosaccharides content 'Kogreen' had relatively higher glucose and fructose content than other four cultivars, therefore the 'Kogreen' has advantage for preparing high quality of silage. In conclusion, among the three different early varieties of Italian ryegrass, 'Kowinearly' was the superior in forage productivity, 'Kospeed' was the highest in feed value and 'Kospeed' had the highest in glucose and fructose content.
