Abstract:
Linear and nonlinear growth models were fitted to identify the best fitted model for the 70 years data of the irrigated area under cereal crops from 1950-51 to 2019-20 and linear & compound growth rates of the data pertaining to the irrigated area under cereal crops were computed. The irrigated area under the rice, jowar, maize, ragi, wheat, barley and other cereal crops was best fitted with the cubic model, where as for bajra the quadratic model was best fitted. Forecasts of irrigated area under different cereal crops for next four years were made. The irrigated area under the wheat crop has recorded with highest significant positive linear and compound growth rates of 2.696% and 3.505% respectively at 1% level. The rice, bajra and maize crops have also recorded with significant positive linear and compound growth rates at 1% level. The ragi, barley and other cereal crops have recorded the significant negative linear and compound growth rates at 1% level.
