Decomposition and Instability Trends in Cumin Production: A Study of Rajasthan

Cumin is an important seed spice crop, with significant medicinal properties. India, the leading producer of cumin, accounts for 70% of the world’s production with Rajasthan and Gujarat contributing nearly 80% of the total area under cumin cultivation. This research addressed the growth instability and variability of Rajasthan’s cumin production. Certain statistical methods, such as the compound growth rate, Cuddy-Della Valle Index, and Decomposition model were used in this research. Area, production, and productivity also revealed positive and significant growth rates, according to the statistics; Jaisalmer recorded the highest productivity growth (18.57%). Rajasthan’s cumin production was primarily driven by the rise of cultivated area, contributing 67.70% to the overall growth, while yield improvements contributed for 11.23%. The interaction effect, representing increased yield on increased acreage, further improved production, especially in the study area. The study concludes that although area expansion significantly influenced cumin production growth, improvements in yield and interaction effects also played a crucial role. This research provides valuable guidance for policymakers and researchers to improve cumin production in Rajasthan under unstable environmental conditions like uneven rainfall, pest and disease etc.

⓿ The area revealed strong growth rates, cumin productivity and production with area expansion accounts for 67.70% of total production growth.

⓿ There was significant variation in cumin production among the major five districts with Jaisalmer displaying a significant variation in productivity and Nagaur revealing the highest variability in both area and productivity.
