Districtwise wheat and rice yield predictions using meteorological variables in eastern Madhya Pradesh

A. K. GIRI, M. BHAN and K.K. AGRAWAL

District wise rice and wheat yield prediction equations were developed for seven districts of eastern Madhya Pradesh using weakly weather data from 1980-2009. The coefficient of determination (R2 ) varied between 0.4 - 0.78 for rice and 0.6 - 0.92 for wheat in different districts. Model performance was evaluated with independent reported data for year 2010 and 2011. As the deviations for both the years were less than ± 15 per cent, the models can be used for predicting the rice and wheat yields in Madhya Pradesh.
