DISCUSSION AND CONCLUSION
The LAI of rice is correlated to the use of solar
energy, dry biomass production and accumulation and
the final production, and can be inputted some models
as one of the significant parameters such as the SAIL
(Scattering by Arbitrarily Inclined Leaves) model. The
LAI estimation using remote sensing is superior to the
traditional method. In this study, the vegetation
indices constructed from replacing the red band
reflectance of NDVI with the all combinations of the
visible band reflectances were used to estimate LAI of
rice.
