This study is part of the KOPIA project, which aims to enhance Sri Lanka’s self-sufficiency in chilli seed production and support agricultural development. It examines the trends in chilli supply and demand in Sri Lanka, available varieties, cultivation techniques, and pest management practices. By sharing these findings with Korean researchers, the study provides essential data to facilitate the expansion of Korean seeds and agricultural equipment into Sri Lanka. Sri Lanka has an annual per capita chilli consumption of 2.32 kg, which is higher than that of its neighboring countries. While fresh chilli production meets local demand, over 90% of dried chilli is imported, underscoring the need for greater self-sufficiency. Various varieties, including ‘MI 2’, ‘KA 2’, and the MI series, are cultivated according to region and season. Recently, Sri Lanka has begun hybrid seed production with the newly developed ‘MICH Hy1’. This study categorizes chilli cultivation techniques into key stages, addressing climate considerations, seedling management, planting density, soil preparation, irrigation, fertilization, weed control, harvesting, drying, seed production, and pest and disease management strategies. Through agricultural cooperation, KOPIA is establishing standardized cultivation practices by integrating research findings. The project also supports the construction of net houses for hybrid seed production and provides field-based technical guidance, contributing to Sri Lanka’s chilli seed self-sufficiency.
