Weixing Cao Yingyong shengtai xuebao 2010
Other claims from this paper (7)
- Observation In rice, wave bands most sensitive to canopy leaf nitrogen concentration lay in the red, blue and red edge regions.
- Observation The ratio index SR(533,565) had the highest determination coefficient (R2) with rice canopy LNC.
- Association The blue nitrogen index R434/(R496 + R401) had a significant linear relationship with rice canopy LNC.
- Method / resource The blue nitrogen index significantly improved prediction accuracy of rice canopy LNC compared with SR(533,565).
- Method / resource In tests with independent datasets, R434/(R496 + R401) estimated rice canopy LNC with an RMSE of 9.67%.
- Method / resource In tests with independent datasets, R434/(R496 + R401) estimated rice canopy LNC with an RE of 8%.
- Recommendation The authors recommend the blue nitrogen index R434/(R496 + R401) as a good indicator of rice canopy LNC.
