In order to search adaptable varieties for the use of soiling and ratooning rice in forage rice cultivation, using 9 high yielding rice varieties including Japonica, Indica and Japonica-Indica cross varieties, dry matter yield, digestibility and nitrogen content were investigated. As a result, among varieties used, the highest dry matter yield over 3kgm-2 was obtained in RAYADA (FRC 14) which is a deepwater rice and extremely late maturing variety. This variety lodged in control plot, because of the high plant length. However the lodging was prevented by soiling. Furthermore, the digestibility and the total nitrogen content of ratooning rice were improved by soiling. Ii is suggested that the use of soilihg and ratooning rice is effective for the variety with high dry matter yield but easy to lodging, and that with low digestibility and low nitrogen content.
