Linear, quadratic, cubic, quartic, exponential and log-logistic models were used for trend analysis. The best fit model was selected based on the least MAPE. Quartic model was the best fitted model for area of chickpea and sorghum. Same model was the best fit for productivity of all selected rabi crops. Quartic model was also fit the best for the production of selected rabi crops except chickpea. Exponential, log-logistic and cubic models were the best fit for production of chickpea, area of wheat and safflower respectively. Further, an attempt was made to predict the production of rabi crops based on best fit model. Increasing trend was noticed in all the crops for next five years in production. The extent of agriculture diversification in Dharwad district was studied using Herfindahl, Simpson and Entropy indices by considering sixteen major crops viz rice, wheat, sorghum, maize, chickpea, minor pulses, groundnut, safflower, sunflower, soyabean, sugarcane, cotton, garlic, coriander and fruits and vegetables. District showed greater degree of diversification under all three indices for entire study period from 2000-01 to 2019-20.EnglishThesis
