Abstract:

The model of L-Y according to the relationship between the dynamic leaf area index and the cotton yield was established based on the experiment data of the plot and field production, and the agricultural theory. The model has the characteristics of simplicity, flexibility, agility, and so forth. The results showed that the model could accomplish the qualitative estimation in the cotton yield with the measurement of leaf area index, the cotton yield and the multi-time LAI from the cotton canopy hyperspectral reflectance by field spectrum radiometer. The relative error of estimation was about 5.44%, and RMSE was 116.2 kg·ha-1, and correlation coefficient between measured and estimated values was 0.836 with a high significance at the 0.99 confidence interval. The referenced model for yield estimation provided from the present research could contribute the improvement of other crop yield remote sensing estimation using dynamic growth information.

Key words: Cotton yield, LAI Estimation of remote sensing, L-Y model
