Abstract:
Sorghum (Sorghum bicolor Linn.) popularly known as Jowar, is the major cereal consumed in India after rice and wheat. India is the world's fifth biggest producer of sorghum. It is the primary food grain of most of the districts in northern Karnataka. The data on yield and area of rabi sorghum in Bellary district were collected for the period 1985-2017 for prediction purpose. The yield was predicted using different polynomial equations like linear and non-linear models for rabi sorghum crop and also forecasted for 2021 AD. The cubic model was found to be the best fitted model and it was used for forecasting of crop yield. The best-fitted model was chosen based upon the highest coefficient of determination (R²), significant Adjusted R² with least MAPE, MAE and RMSE values.
