This study assesses the technical efficiency of potato-producing farms in the Samarkand region of Uzbekistan using farm-level cross-sectional data from 121 households. A stochastic frontier approach (SFA) with a Cobb–Douglas production function was applied to estimate the effects of key inputs - including seed quantity, organic and chemical fertilizers, and labor - on potato yield. Results show that average technical efficiency is approximately 0.85, indicating that farms could increase output by 15% using existing resources and technology. The study highlights the need for optimized input use, improved seed quality, and better management practices to enhance potato productivity in Uzbekistan.
