Recently, the interest and consumption of mini watermelon (Citrullus lunatus Thunb.) are increasing due to nuclear family and one person household. However, there's no research for mini watermelon. Therefore, the purpose of the study is to develop standard cultivation method of mini watermelon. The test cultivar is 'Minimi', which is a small-sized fruit, the rootstock is 'Bullojangsaeng', which is a cucurbit line. Grafted plants were transplanted on April 5, 2017, and harvested in early July. Cultivated types were 3 methods, which are ∩-form, arched, and runner type, and plant spacing were 40, 60, and 80 cm, respectively. The rowth and yield in ∩-form was higher than that of the arched and runner types, and the sugar content was higher a bit. The yield per unit area was about 50% higher than ∩-form, which can be plant density cultivation than that of the runner type. The number of seeds per fruit of 'Minimi' was similar to that of 'Sambokggul', but seed weight was one third lower than that of 'Sambokggul'. The content of lycopene was 30% higher than that of 'Sambokggul' watermelon, and the main sugar content is similar to or slightly less. In conclusion, the ∩-form staking cultivation was superior to the runner type or arched cultivation in terms of fruit setting ratio, yield and quality.
