Other claims from this paper (6)
- Association Plant nitrogen accumulation was significantly related to actual LAI.
- Method / resource Relative LAI was a less biased predictor of NNI than LAI, with R2 values of 0.808 and 0.33.
- Method / resource The authors formulated an LAI-based nitrogen accumulation model.
- Method / resource The authors formulated a relative LAI-based NNI model.
- Method / resource A deterministic model estimated actual LAI from tiller number and height with R2=0.875.
- Recommendation These models could conveniently diagnose rice nitrogen status in the field.
