In winter, most of the energy for a greenhouse crop is supplied during the night. Since watermelon is grown under high night temperature, the experiments were set up to investigate night temperature influence on watermelon in order to obtain the best economic output. Day temperatures ranged from $25^{circ}C$ and 3$0^{circ}C$ ; night temperatures ranged from 2$0^{circ}C$ to 3$0^{circ}C$ at 5$^{circ}C$ interval. Two cultivars of watermelon(Citrullus vulgaris S. ¡®Binna¡¯ and ¡®Kamro¡¯) treated with 30/3$0^{circ}C$ yielded maximum leaf areas, flowers and leaf numbers. 30(14h)/25(10h)$^{circ}C$ or 30(12h)/25(12h)$^{circ}C$ grown plants had higher germination ratio and more dry weight and chlorophyll than those of 30/3$0^{circ}C$ which were the highest temperature integral. Although 25/$25^{circ}C$ and 30/2$0^{circ}C$ regime are same average temperature, the growth of watermelons at 30/2$0^{circ}C$ was significantly higher than 25/$25^{circ}C$. ¡®Binna¡¯ was growing more than ¡®Kamro¡¯ at the same temperature. Leaf area ratio(LAR) was reduced with increasing DIF temperature from 30/3$0^{circ}C$ to 30/2$0^{circ}C$, but leaf weight ratio(LWR) was increased.
