The aim of this study was to analyze the socio-economic characteristics of paddy farmers of different farm sizes in Kancheepuram District, Tamil Nadu. It also sought to examine their resource usage patterns and assess the technical efficiencies at the farm level in paddy production. The research was carried out in Kancheepuram District and focused on 150 paddy farmer households from five different villages within the district. The study utilized a straightforward proportion and the Cobb-Douglas type stochastic production frontier function model to draw its conclusions. The study's findings are significant for policy-making as they provide efficiency indicators to guide farm production planning and identify areas for improving crop production across various farming systems based on efficiency. They also offer insights into long-term techniques for boosting production without the need for additional resources. Moreover, the findings emphasize the importance of providing both formal and informal education to farmers in the region, as education significantly impacts their ability to utilize technology effectively.
