Rice is a staple food crop in Tamil Nadu. Ramanathapuram district has 68 percent of rice cultivation area and 82.12 percent of total demand of water. In this study, an attempt was made to know the technical efficiency of rice production in the district. The technical efficiency of rice production was measured using the Data Envelopment Analysis (DEA) model to assess whether rice output can be increased through improved resource use efficiency or by expanding the area under cultivation. The data were collected from 120 farmers during 2023-24 from two blocks of Ramanathapuram district i.e. Nainarkoil and Kamuthi which have the highest concentration of well-irrigated area and rice cultivation among all blocks in the district. The results of Data envelopment Analysis show that the average technical efficiency is 0.907. This indicates that rice farmers are 9.3 percent technically inefficient and 90 percent current inputs are enough to sustain the production. It means that there is less scope for exploration through enhancing resource use efficiency.
