The ICAR-Central Island Agricultural Research Institute (ICAR-CIARI) organised a Field Day on “Paddy Fallow Sesame Cultivation under Island Conditions” on April 30, 2026, at a farmers’ demonstration field in Chouldari village, South Andaman, to promote summer crop diversification among farmers. The programme focused on creating awareness about the potential of cultivating sesame in paddy fallow lands during the summer season. Scientists from ICAR-CIARI demonstrated the performance of suitable sesame varieties, including JCS-2454 and CUMS-17, and explained recommended sowing time and package of practices for better yield. Highlighting the benefits, the scientists described sesame as a short-duration and remunerative crop with strong potential for diversification in the Andaman and Nicobar Islands. They also emphasised the importance of balanced fertiliser use for sustainable cultivation in paddy fallow areas. Farmers were educated on soil test-based nutrient management, judicious use of macro and micronutrients, and the integrated application of organic manures along with chemical fertilisers to maintain soil health and enhance productivity. Experts noted that balanced fertilisation helps improve yield, optimise input use, reduce unnecessary expenditure, prevent soil degradation, and support long-term agricultural sustainability under island conditions. Addressing the gathering, the Director of ICAR-CIARI urged farmers to utilise paddy fallow lands for sesame cultivation instead of leaving them unused after harvest. He stated that such practices can enhance farm income, diversify cropping systems, reduce dependence on mainland edible oil supplies, and open up opportunities for value addition. Officials from the Krishi Vigyan Kendra (KVK), South Andaman, and the Department of Agriculture, Andaman & Nicobar Administration, also participated in the programme. Around 30 farmers attended the Field Day and interacted with scientists to gain insights into sesame cultivation and its future prospects in the islands.
