This study was conducted to determine the effects of the bottom watering method on seedling growth, temperature of seedbed and working hours. The results of compared conventional watering with bottom watering were as follows: 1. The lowest and highest temperature on surface of bottom watering seedbed were higher about 2-3$^{circ}C$ and 3-5$^{circ}C$ than those of conventional plot, respectively. 2. At 30 days after seeding, flesh and dry weight of seedling in bottom watering seedbed were heavier about 121% and 62% than those of seedling in conventional plot, respectively, while dry ratio of that was lower about 30.2%. 3. Plant height of transplanting seedling in bottom watering seedbed was higher about 4-5cm than that of seedling in conventional plot. Otherwise, ratio of top to root and length of root were not significant. 4. Working hours of bottom watering for growing seedling were reduced 40.9% and 53.4% in primary and secondary seedbeds as compared with those of conventional plot, respectively.
