1) Four seedling raising treatments that dark and chilling, night cooling and short day, interminent cooling, paper made pot promote the flower bud initiates. The dark and chilling treatment affects under conditions that cutting daughter seedlings until June 20th and to set in the cold dtorage from August 26th. 2) The Gibberellin treatment and cold one before the mother plant transplanting promote production of runner when collecting seedlings. 3) High yield needs basal dressing more than 20kg/10a for elevated cultivation. It is desirable to fertilize basal dressing and side one in the ratio of 8:2. High yield needs nitrogen manure that 6kg/10a as initial and 4kg/10a as additional for cultivation. 4) The intrarow spacing from 20cm to 25cm is good in terms of the yield and workability for elevated cultivation. 5) The more earlier lighting start, the more earlier the harvest day of second fruit cluster is, and the more larger yield until February, but the more longer the fruit branch of second fruit cluster grows because the early lighting makes growth and development strong. It is good that the start of lighting from November 5th.
