This study was conducted to investigate effects of waterlogging on the growth, physiological responses, and yield of Kimchi cabbage. The growth of Kimchi cabbage with applied optimized air temperature (set to 20℃) was greater than those with high air temperature (set to 30℃) and the growth significantly decreased by severe waterlogging treatment. The net photosynthetic rate of outer leaves on one hour after waterlogging treatment was higher at 72 hours waterlogging treatment in 20℃ and lower at 24 hours of waterlogging treatment in 30℃. The root activity was decreased by the elevation of waterlogging periods in 20℃ treatment and lower by the short of waterlogging periods in 30℃ treatment. The ratio of formality with non-waterlogging treatment was approximately 64% under 20℃ air temperature and that of range was from 16 to 30% under 30℃. The yield under 20℃ showed higher than that under high air temperature. The non-waterlogging treatment in 20℃ had 4,463 kg/10a, which was the greatest among all treatments, while yields of non-waterlogging treatment at 30℃ were significantly low as 1,082 kg/10a. Results suggested that additional drainage work should be needed to overcome waterlogged conditions of open field during heavy rainfall and should be drainage as soon as possible if there are waterlogging.
