Extension Methods
A variety of methods are employed to transfer research knowledge and technologies to producers. Individual farm visits, regularly scheduled group meetings, technology demonstrations that may involve a field day when hundreds of farmers are invited to observe the latest research results, and transfer of information through mass media are just some of the methods. Some technologies are transferred more effectively through intensive methods such as regular meetings, other are amenable to transfer through less intensive (and usually less expensive) methods such as field days and mass media. Each country must decide what is most cost effective for its public extension system, and each NGO will decide which approach allows it to best achieve its objectives.There is no one method that works best in every situation. Extension
costs and effectiveness will depend on the type of technology, typography of the country, access to mass media, cultural and social factors,and many other variables.
