Understanding the Adoption Dynamics and Impact of TNAU Coconut Tonic: A Study among Coconut Farmers in Tamil Nadu, India

Abstract

Background: In an effort to enhance productivity and address micronutrient deficiencies in coconut palms, the Tamil Nadu Agricultural University (TNAU) introduced the Coconut Tonic, a nutrient-rich formulation applied through root feeding. This tonic contains essential macro and micronutrients that aim to improve the overall health and yield of coconut palms. Aim: To understand the adoption dynamics and impact of TNAU coconut tonic among coconut farmers Methodology: The study adopted an Ex-post facto research design. The sample consisted of Coconut growers in the western zone (Coimbatore, Tirupur and Erode) of Tamil Nadu. A well-structured Interview schedule was developed and applied as a data collection tool to 100 sample. Results: This study, conducted in the western zone of Tamil Nadu, explores the underlying reasons for non-adoption, identifies constraints faced by users, and proposes actionable recommendations to improve uptake. Among the surveyed farmers, 26% had not adopted the TNAU coconut tonic despite being aware of it. Key reasons cited included lack of technical knowledge (35%), high cost (27%), unavailability of the product (27%), and doubts about its effectiveness (8%). Additionally, existing users reported several usage constraints, including irregular product availability, inadequate guidance on dosage and application, labour scarcity, and initial costs. These issues hinder consistent and effective application, especially among small and marginal farmers. To address these gaps, the study recommends strengthening local supply chains, conducting field-level demonstrations, offering financial incentives, and promoting collective action through Farmer Producer Organisations (FPOs). Conclusion: Furthermore, the involvement of trained rural youth and Self-Help Groups (SHGs) in application support could enhance farmer confidence and ensure proper use.
