One of the most popular and extensively utilized palm trees is the Coconut palm, often known as the "tree of life" or "Kalpavriksha." Agricultural economy of Tamil Nadu heavily depends on the production of Coconuts, especially in the Coimbatore area where productivity levels are significantly high. To enhance nut yield and palm health, the Tamil Nadu Agricultural University introduced the TNAU Coconut tonic, a nutrient formulation designed to supply essential macro-and micronutrients along with growth regulators. This study was undertaken with a sample size of 105 Coconut farmers selected purposively from 3 major Coconut-growing blocks of the Coimbatore district, namely, Kinathukadavu (45), Pollachi North (30) and Pollachi South (30). Primary data were collected through personal interviews using a structured schedule. The study examined the socio-economic profile, adoption behaviour, farmer satisfaction and constraints confronted by farmers in adopting TNAU Coconut tonic. The results revealed that most respondents had higher secondary education, agriculture as their primary occupation, an annual income between ₹5–10 lakhs and operational holdings of 5–10 acres under tall varieties. Agricultural scientists and State Department officials were the primary sources of information and most farmers purchased the tonic directly from TNAU centers and applied it once a year even though the recommendation is twice a year. The paired t-test results indicated a significant increase of 131.24 nuts/tree after application. Kendall’s Coefficient of Concordance Kendall’s (W) was 0.655, showed a high level of farmer satisfaction, mainly due to yield improvement and better palm health. The high cost and limited availability of the tonic were identified as major constraints. While subsidies, demonstrations and integration into government schemes may improve adoption, the study lacks a cost-benefit or economic feasibility analysis, which is essential for evaluating its practicality. This should be considered as a limitation and addressed in future research.
