Values are means of three replicates ±SE. Values followed by the similar lower case letters within columns for waterlogging treatments don’t differ significantly according to Duncan’s test (P ≤ 0.05).The different application levels of nitrogen were N1 (0 kg ha−1), N2 (30 kg ha−1), N3 (60 kg ha−1) and N4 (90 kg ha−1). D0, refers to without waterlogging; D6, refers to waterlogging for 6 days and D9, refers to waterlogging for 9 days. 0 day refers to the days after nitrogen application.
