Nitrogen Use Efficiency Regulates Drought Stress in Pearl Millet Genotypes: Morpho-Physiological Evaluation

In this paper, the author discusses effects of drought stress on pearl millet genotypes during vegetative stage development and plant’s mechanisms for survivability under with various nitrogen treatment regimes. A total six conditions were imposed plants, i.e., N0 (no Nitrogen-0 mM), N0+PEG-10%, LN (low Nitrogen-2.5 LN+PEG-10%, HN (high Nitrogen-7.0 HN+PEG-10%. Five days moderate caused significant morphophysiological changes, as evidenced by a reduction in fresh dry biomass, well relative water content (RWC), electrolyte leakage, chlorophyll fluorescence,. plant biomass RWC when compared to controls was seen. Reactive oxygen species (ROS) lipid peroxidation (MDA) levels increased shoot response along loss membrane integrity. regime regulated stress. relation N0-treated batches, proline accumulation N-treated batches. Results revealed that GHB-538 is less tolerant different N conditions, while RHB-234 223 showed better tolerance treatments. The significance study uncover regulatory role over millet.
