Abstract

Eastern India accounts for more than half of the rice crop area in the country where rainfed rice is
predominant. Rice is main food crop of Monsoon season in Chhattisgarh. Production of rice is mainly
dependant on monsoon rainfall and weather prevailing in the season. Forecasting of yield of rice is useful for
planning of food storage, export and pricing in the country. It is established that rice yield is correlated with
prevailing weather in the season. Modified Hendricks and Scholl model which consider weather from sowing to
week prior to forecast week is employed to develop regression model in different districts. The models used to
forecast district level yield of rice in Chhattisgarh in mid-season of 2014 and 2015. Forecast yield obtained is
validated with actual yield of corresponding year to find the accuracy of developed model. Forecast accuracy is
less than 10% in 6 districts in 2014 and 4 districts in 2015.
