Abstract
Cereals have been considered as the principal component of human diet for thousands of years and have played a major role in supplying nutrients to human civilization. Cereals represent around 37 per cent of the total cultivated land in Karnataka state. For the current study three major cereal crops such as Rice, Maize and Jowar was considered. In this research, an effort was made to study the growth rate and trend in area, production and productivity of major cereal crops of Karnataka state using Linear,
Quadratic, Cubic, Exponential and Log-logistic model by considering secondary data for the time period of 15 years from 2005-06 to 2019-20. The best fit model model was selected based on the minimum value RMSE. Linear, exponential and cubic models were found to be best fit. Here in this research an attempt was made to evaluate growth rate in area, production and productivity of major cereal crops in Karnataka using compound growth rate formula. Growth rate was found to be decreasing for both Rice and Jowar but for Maize crop the growth rate was increasing in nature. Further the attempt was made to measure the change in composition that is resource use efficiency was estimated using cobb-douglas
production function. It is observed that for both Rice (1.253) and Jowar (1.614) returns was found to be increasing where as decreasing returns was observed for Maize crop (0.699).
