This study analysed the resource use and technical efficiency of aggregatum onion production in peri-urban areas of Coimbatore city of Tamil Nadu. Cobb-Douglas production function was used to measure the resource use efficiency of the aggregatum onion production. Data Envelopment Analysis (DEA) was used to measure the technical efficiency of the farms. The results showed that the average yield of aggregatum onion was 10 tonnes per hectare with a coefficient of variation of 19 percent. The average net return was 81,175 with the B: C ratio of 1.48. The study on resource use efficiency revealed that the quantity of farmyard manure, phosphorus, and nitrogen had a positive and significant influence on aggregatum onion yield. The MVP ratio to MFC was greater than one for all the significant variables indicating the underutilization of resources, and there existed the possibility of enhancing their yield by increasing their use. The overall mean technical efficiency of aggregatum onion was 0.89, which indicated the possibility of increasing the yield of aggregatum onion by adopting better technology and cultivation practices.
