• Documented sixty agriculturally based ITKs and it’s impact and several technological interventions were introduced in the Sundarban coastal agro-eco system.
• First time; a novel concept of “Social-Dynamic Index” was introduced in extension research and estimated social dynamics among drip and non- drip users of sugarcane, onion and leaf banana cultivators based on eight social indicators.
• Developed a novel concept to estimate the water use efficiency in extension research and water management technologies were evaluated at farmers’ field through FPARP.
• Extensive survey was carried out in 22 districts of Tamil Nadu state and an inventory of farmers’ practices for inclusive development of sugarcane production system was prepared with forty case studies.
• Survey research carried out to study the impact of drip irrigation in cotton cultivation Tamil Nadu, Maharashtra and Gujarat stated.
• Transfer of Sugarcane, Cotton and Banana technologies to different stake holders and through various mass media and print media. Developed several extension teaching aids.
