Plants were harvested from control and waterlogging
treatments and after termination of waterlogging. Plants
were dug out gently and roots were washed thoroughly
for counting of root nodules. Leaf area was measured
using leaf area meter (Model 3100, LI-COR, Inc
Lincoln, NE, USA). Plant samples were dried in hot
air oven at 80 °C till constant weight was achieved.
Plant growth rate (GR) was computed following the
method of Gardner et al. 1985.
