Abstract

The study was carried out across all the districts of Karnataka. The secondary data on area and production of major food grains of all the districts for the duration from 1950-2019 will be collected from ‘Karnataka at a Glance’ published by the Directorate of Economics and Statistics, Government of Karnataka, Bangalore. To analyse the trends in area and production of major food grains (Paddy, Jowar, Bajra, Ragi) of Karnataka using linear, cubic, exponential and log-logistic model. The best fit model was selected based on the minimum value of RMSE. Exponential model was found to be the best fit model for area and production for Bajra, Ragi, area and production had linear growth for Paddy, Jowar had exponential growth over area and linear growth over production crops during 1950 to 2019.
利用线性和非线性统计模型确定卡纳塔克邦主要粮食谷物面积和产量的现有模式
研究在卡纳塔克邦的所有县展开。从班加罗尔卡纳塔克邦政府经济和统计局出版的《卡纳塔克邦概览》中收集 1950-2019 年期间各县主要粮食谷物面积和产量的二手数据。使用线性、立方、指数和对数-逻辑模型分析卡纳塔克邦主要粮食谷物(稻谷、焦瓦尔、巴吉拉、拉吉)的面积和产量趋势。根据均方根误差的最小值选择了最佳拟合模型。1950-2019年期间,巴焦拉、糙米的面积和产量以指数模型为最佳拟合模型,稻谷的面积和产量以线性模型为最佳拟合模型,焦瓦尔的面积以指数模型为最佳拟合模型,产量以线性模型为最佳拟合模型。
