Application of Hazell decomposition model on turmeric production variability in Karnataka

Abstract

Turmeric is one of the most important tuberous rhizomes or underground stem grown across the world. Turmericis also considered Rhizome which are rich curcumin content, which is responsible for many of its medicinal properties suchas Antioxidant, Anti-inflammatory, Antitumor, Anti-carcinogenic, Anticoagulant and Antifungal. It is considered as greatestnatural medicine available for human beings. The current study is confined to Turmeric crop grown in Karnataka. Toexamine the growth and instability in area, production and productivity of Turmeric for a period of 24 years (2001-2023)data was used. Exponential growth rate, Cuddy valley instability index and hazell’s decomposition analyses were employedto analyse the data. During the study period, there exhibits increasing growth in area (6.22%), production (7.48%) andproductivity (1.18%). The instability analysis revealed that area under turmeric cultivation was moderately unstable thanproduction and productivity. Hazell’s decomposition analysis reported that increase in the mean average production wasmainly due to change in area-yield co-variance (7.86%). Change in mean area (89.87%) and change in mean yield (2.69%)contributed to the variability in the turmeric production.
