Abstract/Description: | 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. |
