Rice seedlings of three different age groups,
i.e., 30, 45 and 60 days old were grown with three different
N levels, i.e., 0, 20 and 40 kg ha-1 for two consecutive
years under waterlogged condition. The highest yield was
obtained with 40 kg N ha-1 in crop grown with 60 day old
seedlings in both the years. Higher dosage of N application
as mud ball showed higher stomatal conductance, net
photosynthesis and transpiration. The response of N was
better in crop grown with older seedlings. Grain yield
showed significant positive relationship with net photosynthesis
rate (r = 0.82 * * ) and carboxylation efficiency
(r = 0.81 * *) than with stomatal conductance (r = 0.66),
and could be critical determinant for better yield in crop
grown with older seedlings at higher N level under
waterlogged condition
