Drip irrigation is a highly efficient water management system that has the potential to significantly improve water use efficiency and crop productivity, especially in water-scarce regions. However, despite its advantages, the widespread adoption of drip irrigation faces various constraints, including economic, technical, administrative, and socio-psychological challenges. This study focuses on the constraints encountered by farmers in Tamil Nadu, a state where the government has implemented several initiatives, such as the Tamil Nadu Irrigated Agricultural Modernization Project (TN-IAMP) and the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY), to promote drip irrigation adoption. The research examines the barriers to effective implementation of drip irrigation in eight sub-basins of Tamil Nadu, selected based on the highest number of TN-IAMP beneficiaries. A total of 559 respondents from these sub-basins were surveyed to understand the key challenges they face in adopting and maintaining drip irrigation systems. The findings highlight significant economic constraints, such as high installation costs and limited access to credit, as well as technical issues like clogging of emitters and inadequate maintenance. The study also identifies administrative and socio-psychological barriers that hinder adoption. The paper concludes with recommendations for overcoming these challenges, including improved financial support, better technical training, and more efficient administrative processes, to enhance the sustainable adoption of drip irrigation in Tamil Nadu. However, its widespread adoption faces several constraints, categorized into economic, technical, administrative, and personal & socio-psychological barriers. Economic challenges, such as high initial installation costs, expensive equipment, and limited access to credit facilities, are significant deterrents for farmers. Technically, issues like frequent clogging of drippers, maintenance requirements, and inadequate awareness hinder effective use. Administrative constraints, including unreliable power supply, delays in subsidies, and the non-availability of spare parts, further exacerbate the adoption challenges. Additionally, personal and socio-psychological factors, such as lack of motivation, resistance to change, and frustration from previous system failures, prevent farmers from fully embracing the technology. Addressing these multifaceted barriers through targeted interventions and support systems is crucial for enhancing the adoption of drip irrigation, ensuring sustainable water management, and improving agricultural productivity in the region. The findings highlight the need for comprehensive policy reforms, improved access to financial resources, and increased farmer education to overcome these constraints.
