| Summary: | Rice is an important crop in Nepal. Despite being an important crop, several challenges have
led to the increasing rice imports in the country. A constraint still remains in the proper rice yield
estimation mechanisms still unapplied. Remote sensing technologies have been successfully deployed
in the yield prediction where the satellite collected spectral information is used to derive the vegetative
indices. Such vegetative indices are empirically related to the yield. This research correlates the
vegetation indices (NDVI and EVI) derived from the MODIS satellite data with the district wise rice
yield of Terai region of Nepal. The utilisation of MODIS cropland cover as rice masks also presents its
usability when long term rice mapping is unavailable. The results showed a significant positive
correlation with rice yield and vegetation indices in almost all districts, except some districts showing
no such positive association. The applied method of computing vegetation indices can be applied in
future rice yield prediction. With the growing applications of satellite based remote sensing, this
research presents an example of rice remote sensing in Nepal. |
