Present study was undertaken to assess the impact of ‘Seed Production Project’ of the Department of Agricultural Extension (DAE) by exploring the changes in knowledge, attitude and practices of the beneficiaries. Data were collected by the researchers from randomly selected 205 beneficiaries of 12 villages of three project upazila using pre-designed interview schedule. ‘Before-after study without control’ method was adopted for assessing the project impacts. Seed production project yielded significant improvement in knowledge, attitude and practices (production, processing and storage) of beneficiaries. They become conscious about ‘good quality of seed and seedling’, ‘optimum seedling age’, ‘ use of balanced fertilizer’, ‘critical stages of rice for nitrogen application’ and ‘good quality of seed container’. Focused respondents were moderately to highly maintaining the requirements in production, processing and storage stage to facilitate quality rice seed. However, there is ample scope to improve on proper land selection and preparation, removal of plant debris, storage structure and maintaining atmospheric variables.
