Abstract

To estimate leaf area index (LAI) and total dry matter (TDM) of rice canopy by a non-destructive method, the spectral reflectance from the canopy was measured weekly by the spectroradiometer during the growing season. The reflectivity of visible band remained less than 0.1 throughout the growing season, but that of near infrared band varied from 0.1 to 0.5, showing the positive correlation with LAI. Vegetation index by narrow band (10 nm), R910/R460 showed strong correlation with LAI and TDM
