Growth rate, instability and trend analysis of area, production and productivity of turmeric in India

The present study was conducted to estimate the growth rate, instability and trend in area, production and productivity of turmeric in India from period 1950-51 to 2022-23. Statistical tools like compound annual growth rate and Cuddy-Della Valley Index were used to estimate the growth rates and instability, respectively. The study period 1950-51 to 2022-23 was further sub-divided into three sub-periods, viz., period I (1950-51 to 1989-90), period II (1990-91 to 2022-23) and overall period (1950-51 to 2022-23). The study revealed that the area under turmeric showed the highest positive and significant growth rate per annum during period – II and exhibited less instability in all the periods. Similarly, production and productivity of turmeric in India exhibited the highest positive and significant growth rate per annum during the overall period and exhibited less instability during period -II. The area under turmeric in India showed steady and increasing trend during the study period while production and productivity of turmeric in India exhibited increasing trend with fluctuations throughout the study period.
