The study has estimated technical efficiencies and identified the determinants of technical efficiencies among the potato farmers in the Farrukhabad district of Uttar Pradesh. The data for the study have been collected from its 300 respondents, which include 120 farmers, 30 individuals owning cold storage, and a sample consisting of 60 consumers and 90 traders, using a structured questionnaire and analyzed through a stochastic frontier production function for 2022-2023. The results showed that farmers of potatoes within the zone were experiencing diminishing returns to scale in the utilization of farm inputs. It has also been proved that storage conditions are favorable for the maintenance of potato quality, while low losses can be achieved without using chemicals. The researchers demonstrated how the cold storage techniques reduce costs across the value chain in the product and, therefore, keep the farmer's price competitive. The technical efficiency ranged from 63% to 99%, with a mean of 90%, which showed great potential for productivity growth through better efficiency. The main factors influencing the technical efficiencies are the level of education, experience in farming, off-farm income, and variety of potatoes. The study concluded that policy interventions necessary for enhancing technical efficiency in potato farming in the region should target such determinants
