Sugarcane is one of the traditional crops grown abundantly across the state of Karnataka. Maize is cultivated for various purposes including grain, fodder, sweet corn, etc. The secondary data on area and production of sugarcane and maize along with the weather parameters of Karnataka was collected for the period of 30 years from 1991 to 2020. In this study an attempt has been made to elicit the trend in area and production of sugarcane and maize along with the forecasting of production of both the crops. Further an attempt has been made to know the impact of area and weather parameters on the production of sugarcane and maize crops. Trend analysis was performed by fitting different models such as linear, quadratic, cubic, exponential models and Generalized additive model (GAM). Based on the maximum R2 value best fitted model was selected. GAM was best fitted for area (64.7%) and production (85.1%) of sugarcane, whereas Exponential and GAM was best fitted for production (49.3%) and area (95.1%) of maize crop respectively. Production of sugarcane and maize crop was forecasted for the period of 5 years from 2021 to 2025 using GAM and Exponential model respectively. By employing Multiple Linear Regression (MLR) and Step-wise Multiple Linear Regression (SMLR) it was observed that area had significant positive influence on production of both the crops.EnglishThesis
