This study was examined for the effect of tuber size, bud and tuber removal, and tuber cutting on growth of Eleocharis kuroguwai Ohwi. Elongation of plumule and radicle, and the weights of tuber, rhizome and shoot were increased as tuber size enlarged. The weights of shoot and tuber reduced by bud planting without tuber at 15 days after budding, however number of tubers were increased compared with normal tuber. When cross-cutting tubers were seeded, the weights of shoot, rhizome and tuber were produced as 84 %, 85 %, 71 %, respectively compared with normal tuber, and the number of tubers was not influenced. The weights of tuber, rhizome and shoot lowered with removal, and there were a great number of tubers at bud removal of 15 days after budding. Tuber of E. k. contained as nonfibrous 78.9gr, phosphorus 77mg, iron 16.8mg, niacin 1.3mg per 100gr edible portion. The positive correlations were observed between shoot weight and tuber weight, and number of tubers
