Other claims from this paper (5)
- Association Chlorophyll concentration and leaf nitrogen concentration had linear relations across treatments and varieties.
- Method / resource Thickness-adjusted LCC scores related linearly to leaf nitrogen concentration across treatments and varieties.
- Intervention effect Rice leaf spectral reflectance did not show stress-dependent pattern changes.
- Recommendation The authors concluded that SPAD and LCC could aid nitrogen management in moderately unfavorable rice environments.
- Recommendation The authors recommend regional variety calibration to improve precision of leaf nitrogen estimates.
