Other claims from this paper (15)
- Method / resource Before merging, the leaf calibration correlation coefficient for nitrogen content in rice was 0.945.
- Method / resource Before merging, the stem calibration correlation coefficient for nitrogen content in rice was 0.928.
- Method / resource Before merging, the whole-plant calibration correlation coefficient for nitrogen content in rice was 0.864.
- Method / resource The leaf calibration model was recorded with relatively high accuracy compared with the models for each part of the rice plant.
- Method / resource The PLS-developed calibration equation was more accurate than the MLR-developed equation for rice plant nitrogen.
- Association The calibration equation was sensitive to variety and location variations in rice.
- Method / resource After merging samples, the leaf R2 value of the calibration was 0.950.
- Method / resource After merging samples, the stem R2 value of the calibration was 0.974.
- Method / resource After merging samples, the whole-plant R2 value of the calibration was 0.940.
- Method / resource After removal of outliers, R2 values increased to 0.998, 0.995 and 0.997 for the calibration models.
- Association Biases of the calibration were reduced in the leaf, stem and whole plant.
- Association Slopes of the calibration were high in the stem.
- Association Standard deviation was reduced in the stem.
- Association R2 was high in the stem and whole plant.
- Recommendation The authors conclude that a robust calibration equation can be updated by the merge function and multivariate calibration.
