Abstract：We studied the impact of waterlogging at flower-pod stage on physiological traits and yield of soybean grown in a lysimeter in attempts to improve drainage management of soybean fields. The results showed that the number of pods, weights of 100-pellets and yield of the soybean decreased due to waterlogging, and that the rela-tive yield was negatively related to accumulated depth of waterlogging (R=0.9489). Reduction in soybean yield increased with prolonged duration of waterlogging. To sustain growth and yield of soybean, therefore, the ground-water table should be dropped to below 30 cm of depth in 5 days after waterlogging occurred.
