The extension department has been established in 1965 as per the recommendation of ICAR under the scheme of establishment of the extension wing. The post of assistant professor of extension was filled in January, 1965 and that of the professor of extension in December, 1965 which was recognised as extension specialist. As a result of the organisation of the department; the extension departments of the veterinary colleges were merged with the department of extension education and rural sociology of the agriculture faculty in 1968. Thus the extension wing started working soon after its establishment. Dr. R.M. Bakshiwas appointed as head of the department in 1973.
