Statistical Analysis of Area, Production and Productivity of Chickpea (Cicer arietinum) and Black Gram (Vigna mungo) across Selected Locations in Chhattisgarh, India

This study examines the spatio-temporal trends in cultivation of two important pulses—chickpea (Cicer arietinum) and black gram (Vigna mungo)—across selected agro-ecological locations of the state of Chhattisgarh, India during the period 2015–2019. Using secondary data from state and district agricultural statistics, we analyse changes in area under cultivation, production output and derived productivity (yield = production/area) for the two crops. Further, compound annual growth rates (CAGR), correlation coefficients among area, production and productivity, and regression models are utilized to understand key relationships and variation across locations. The results show that chickpea has witnessed modest growth in area and production but limited improvement in productivity, while black gram displays greater spatial heterogeneity and overall lower yields with little upward trend. Strong area-production correlations indicate production increases are largely driven by area expansion rather than yield improvement. The large yield gaps observed—particularly for black gram—highlight the need for targeted agronomic and extension interventions in low-performing locations. The study recommends enhanced varietal adoption, nutrient management, and location-specific extension support to bridge productivity gaps and promote sustainable pulse production in Chhattisgarh.
