Other claims from this paper (9)
- Intervention effect Higher N fertilizer rates significantly increased aboveground N concentration.
- Method / resource The hybrid indica critical N dilution model was Nc=4.02DM−0.42 with R2=0.97.
- Method / resource Curve verification root-mean-square error was 0.23.
- Method / resource Curve verification normalized root-mean-square error was 10.61%.
- Observation NNI ranged from 0.58 to 1.31.
- Observation Nand ranged from 109 to –55 kg ha−1.
- Association NNI had a linear relationship with Nand across growth stages.
- Association NNI had a linear-plateau relationship with relative yield.
- Method / resource The authors conclude the models can diagnose N status and support real-time N fertilizer management.
