다국어 초록 (Multilingual Abstract)

These study was carried out to obtain the basic data which are necessary for producing good quality of fruits required for strengthening the competitiveness of sweet persimmon in the markets.
In 1997, there were 4 irrigation periods: April to July, April to August, April to September and April to October, and in 1998 and 1999, 2 irrigation periods: April to September and from April to October, and persimmon trees were irrigated in amount of 15mm when rainfall was less than 30mm in two weeks during these irrigation periods. The rainfall in 1997 during September and October, which were the main fruit expansion phase, was shorter than average year's rainfall, but no water shortage in 1998 and 1999. During August, September and October, the monthly soil moisture in non-irrigation field was deficit in 1997, as compared to irrigation field, but no differences as affected by irrigation treatments in 1998 and 1999. In 1977 in which rainfall was comparatively shorter than average year's rainfall during fruit growing season, the fruit weight were increased to 19%, 14% in irrigation periods from April to September and from April to October, respectively, as compared to control, but there were no differences in peel color and soluble solids as affected by the irrigation treatments.
