This experiment was carried out to investigate the effect of remaining leaf numbers after flower stalk cutting, corm digging time, and corm size on the corm production and flowering in next culture. The less leaves remained after flower stalk cutting, the less corms and cormels were produced. After flower stalk cutting, the minimum number of leaves was four for new corm and cormel production and flowering in next culture. The optimum digging time of corms was 60 days after flowering for the use in next culture. In order to use corm only, it is possible to harvest 30 days after flowering. Nitrogen, phosphorus and potassium content decreased, but starch content increased 30 days after flowering. The larger the corm size was, the more corm numbers and flowering ability increased. But there was no differences in number and flowering ability and cormels produced by corms planted between 4-5cm and above 5cm diameter
