Potato Production Efficiency: A Data Envelopment Analysis Approach

Abstract

A data envelopment analysis (DEA) was used to determine the technical efficiency of potato producers in Himachal Pradesh, India. The farmers who cultivate the major varieties Kufri Himalini and Kufri Jyothi displayed apparent differences in performance, with an average technical score of 70.8% and 80.3%, respectively. Many farmers operate below the efficiency frontier, highlighting considerable scope for increasing yields without the use of additional inputs. Through the application of k-means clustering and slack variable analysis, this study determines whether excess inputs can be conserved, such as fertilizers, labours, and pesticides. In potato production, optimal input usage can enhance productivity and ensure environmental sustainability. This study provides evidence-based recommendations to help policymakers and extension agencies strengthen the efficiency and sustainability of smallholder agriculture in the country.
