Wheat Production Estimates Acreage was estimated using Remote Sensing data Yield was estimated from a combination of Remote Sensing based models, agro-meteorological models and crop simulation model Then, a loss factor was determined by developing an empirical model between NDVI and crop yield (from CCE data) and yield loss per unit NDVI decrease (from 2014 to 2015) was computed. Accordingly estimated yield, at district level, was reduced.
