Potato is a crucial vegetable crop in the north-eastern hilly states of India and ranks among the most widely consumed staple foods in the region. However, productivity remains well below the national average, with yields of 8.55 MT/ha compared to 25.79 MT/ha nationally. Despite advanced technologies, challenges persist regarding data availability, access, and infrastructure in rural Northeast India. Farmers often lack knowledge of efficient irrigation schedules, soil management, and diversification strategies to counter climatic variation due to technological barriers. This study evaluates adoption of recommended potato production technologies and identifies constraints faced by farmers. Data were collected from a purposive sample of 480 farmers across Assam, Meghalaya, Nagaland, and Tripura. Percentage analysis described socio-personal characteristics and adoption levels of recommended practices, while negative binomial regression identified determinants of adoption. Constraints were analyzed using a severity index and weighted mean score. Results indicated that planting time, seed quality/selection, and planting methods were most critical, with adoption rates of 73.12%, 57.91%, and 56.66%, respectively. Of 13 recommended practices, most farmers adopted seven. Regression revealed education and potato farming income had a significant positive effect at the 1% level on adoption. Among nine categories of constraints, production issues were most severe, followed by storage and extension service limitations. Policy interventions should improve access to extension services, ensure timely delivery of inputs, promote credit, and provide targeted training in agronomic practices. Active farmer involvement in decision-making and collective action through cooperatives can further enhance technology dissemination and adoption.
