Mungbean in Rajasthan: Growth performance and decomposition analysis

The present study was conducted to examine the growth performance and relative contribution of area and yield to the change in mungbean production in Rajasthan. Three districts, viz., Nagaur, Jodhpur, and Pali, which together contribute more than 50% of the total area under mungbean in Rajasthan, were selected for the study. Time series data were collected from 2000- 01 to 2019-20 and to study the decadal performance, the entire period was bifurcated into two sub-periods: 2000-01 to 2009-10 (sub-period I) and 2010- 11 to 2019-20 (sub-period II). The Compound Annual Growth Rate (CAGR), Cuddy Della Valle Index (CDVI), and Decomposition Analysis Model were employed for analysis. Results revealed that the growth rate was positive for area, production, and productivity of mungbean at the state and district levels. The instability index was found to be greater than 30 in most of the cases, which indicates the high variations in area, production, and productivity of mungbean during the reported period. The sub-period II witnessed a comparatively higher positive growth rate accompanied by a lower instability index than the sub-period I. The study further revealed that the area effect was greater than the yield effect in most of the cases, which indicates its greater share in the increase in mungbean production at state and sampled district levels. With the observed positive growth rate in area and its contribution to change in production, the state has scope to increase the area coverage under mungbean, as 55% of the districts in Rajasthan have less than 1% of the total area under cultivation.
