In the present study, Knowledge Index (KI) and Adoption Index (AI) were developed to measure the knowledge level and Adoption level of Chilli Technology of farmers in Char Area of Bangladesh. A preliminary test of thirty knowledge items related to chilli cultivation technology was administered to 38 chilli farmers who were involved in chilli production in island char areas. Data were collected during February to March 2008 through interview schedule. The Knowledge Index (KI) ranged from 71 to 99 and Adoption Index (AI) ranged from 68 to 98. A correlation coefficient of KI and AI was 0.97 which indicated that a high relation exists between Knowledge Index (KI) and Adoption Index (AI). The major constraints are ignorance about improved seeds and cultivation practices, chemicals with doses and method of application, scientific method of storage, etc. The major economic and physical constraints are the high cost of the seed of improved cultivars, non-availability of funds, etc. It was recommended that the farmers be guided through extension visits to teach them adoption of new technologies related to Chilli production. The study will help researcher, agricultural extension worker, policy maker and NGOs to address and analyse the issues related to knowledge, adoption and constraints of not only chilli production but also other field and horticultural crops production.

Key words: Knowledge index, adoption index, chilli, constraint analysis, island char area, Bangladesh
