e0“Under moderate salinity, most measured parameters including shoot dry weight (SDW), shoot N content at active tillering (SNC), effective panicle number (EPN) and GY increased significantly with N levels, but to a lesser extent than those of plants grown under non-saline conditions.”

Other claims from this paper (12)
- Intervention effect High salinity nullified nitrogen effects on rice growth and grain yield.
- Observation Nitrogen efficiency for grain yield was 15.09 under non-saline conditions with increasing N.
- Observation Nitrogen efficiency for grain yield was 6.82 under moderate salinity with increasing N.
- Observation Nitrogen efficiency for grain yield was 1.94 under high salinity with increasing N.
- Intervention effect Under moderate salinity, increasing nitrogen significantly raised effective panicle number and grain yield.
- Intervention effect Increasing nitrogen significantly reduced agronomic NUE at active tillering regardless of salinity.
- Intervention effect Increasing nitrogen did not significantly reduce agronomic NUE at heading or maturity.
- Association At moderate salinity, agronomic NUE correlated positively with absorption NUE at active tillering (0.90).
- Association At severe salinity, agronomic NUE correlated positively with absorption NUE at active tillering (0.97).
- Association At moderate salinity, agronomic NUE correlated with physiological NUE (0.67).
- Association At severe salinity, agronomic NUE correlated with physiological NUE (0.62).
- Recommendation The authors recommend investigating improved nitrogen uptake at active tillering to enhance NUE, panicle number and grain yield under salinity.
