that covered various growth stages. Coinciding with hyperspectral measurement,Â biophysical parameters such as leaf area index (LAI), SPAD value were measured on
ground during the airplane passed over area of interest (AOI). Rice yield was measuredÂ at the time of final harvesting by random selected yield (ubinan method) for eachÂ sampling area. In finding the best correlation among canopy hyperspectral reflectanceÂ with crop development, optimal individual waveband explored with involving all possibleÂ waveband combinations to obtain the best fitted two-pair waveband related to cropÂ biophysical parameters. Normalized Difference Spectral Index (NDSI) was applied
from spectral transformations (obtained from optimal waveband selected by exploringÂ all possible waveband) to improve sensitivity analysis on plant. Canopy hyperspectral
provided information about plant, soil and water background when plant canopy donâ€™tÂ completely cover soil surface yet. The present study was directed to examine spectral
indices and establish the relationships between biophysical parameters of rice by usingÂ partial least square regression (PLSR) technique.Â
