Examining the yield gap in sunflower farming: Insights from Karnataka’s Chamarajanagar district

Abstract

This study examines the disparity in sunflower production yields between small and large farmers in Karnataka's Chamarajanagar area, which is well-known for growing sunflowers. Data on the discrepancy between potential and actual yields was gathered from 120 respondents in 12 villages using an ex post facto study approach. The actual yields for large farmers and small farmers were 4.12 and 3.31 quintals per acre, respectively, but the potential yield was estimated to be 5 quintals per acre. This led to yield gaps of 0.88 and 1.69 quintals per acre. The yield gap index, which measures differences in knowledge, resource availability and access to better agricultural methods, was much greater for small farmers (33.80%) than for large farmers (17.60%). A statistical study showed that the two groups' yields differed significantly, with small farmers' output being hindered by both biological and socioeconomic factors. The results highlight the necessity of focused interventions, such as resource assistance and training, to close the yield gap and improve the sustainability of sunflower production. Improving food security and lowering India's reliance on imported edible oil require addressing these issues.
