Growth rate and instability analysis of sugarcane in selected states of India

The present paper deals with the analysis of growth and instability in production, area and yield of sugarcane for some selected states of India by estimating compound growth rate (CGR) and Cuddy-Della Valle (CDV) instability index on the basis of time series data on production, area and yield of sugarcane pertaining to the period 2010–2019 for the concerned states. The statistical measures viz. percentage change and percentage share have also been incorporated in the study. The percentage change is used for exploring the trend pattern of sugarcane during the concerned period by considering the base year as 2010. Moreover, the values of statistical coefficients viz. coefficient of variation (CV) and coefficient of determination (R²) have been obtained for the production, area and yield of sugarcane in the concerned states. The values of R² have been computed by fitting linear models to the respective time series data on production, area and yield of sugarcane in the concerned states.

• The present study is based on secondary time series data on sugarcane pertaining to the period 2010-2019.

• The percentage change in production, area and yield of sugarcane has been computed for exploring the respective trend pattern of sugarcane in selected states of India.

• The percentage share of production, area and yield of sugarcane for the entire states of India in the year 2019 have been depicted graphically.

• The instability index developed by Cuddy-Della Valle is obtained in the study to measure the level of instability in production, area and yield of sugarcane.

• The compound growth rates (CGRs) for production, area and yield of sugarcane have been obtained in selected states of India.
