Abstract
Cotton is the main source of commercial fiber. In India's economy, it is one of the most important cash crops. This study used secondary data to look at the growth in cotton crop area, production, and productivity in the Ballari district of Karnataka over the last 46 years (1970–2016).The findings demonstrated that the cotton crop's area, production, and productivity increased significantly over the study period. In terms of area (2.8 per cent), production (3.3 per cent), and productivity, the Ballari district increased significantly (3.0 per cent). To know more about cotton crop acreage, production, and productivity trends in the Karnataka district of Ballari, The quartic model was determined to be the best fit among the various polynomial models fitted for the acreage, production, and productivity of the cotton crop in the Ballari district, with an RMSE of 12.9 and an adj.R2 value of 0.8. The best fit for production was a quartic model with an RMSE of 18.7 and an adj.R2 value of 0.87, while the best fit for productivity was a cubic model with an RMSE of 50.6 and an adj.R2 value of 0.8.
