oin contact with other government officers, such as education officers; w frequently listens to radio farming programmes or frequently reads magazines; o member of co-operative society; oin possession of title deeds. If Dr Mbula is right, you should pay particular attention to the degree of education and training a farmer has accumu- lated, to his financial and social status, when you are choosing a contact farmer. However, remember that you are responsible for communicating your information to all farmers in your area. You cannot rely, in total, on selective contact farmers with education and financial status. Look hard for the social and other ties that bind the less affluent farmers and their families. Look for other commonalities, such as interests in children's schools, church bodies, and other groups. Media Messages A surprisingly high number of the farmers in the research sample were found to be listeners to the radio, readers of newspapers and magazines, and visitors to agricultural shows and exhibitions. A successful project uses such media sources to reinforce the face-to- face meetings with farmers. To produce such educational and informative material is not your own responsibility; but you will need to be familiar with the kinds of information transmitted through these channels so that you can relate and time your own information and material to these mass media messages. In the world of selling agricultural products, it is said that two factors are vital: Advertisements in the national press and broadcasting; The travelling salesman. However good one of these factors may be, it cannot be really successful without the other. The salesman gains his credibility from the national advertising. But farmers often need the direct contact with a salesman before they actually buy a product. A similar pattern holds for extension projects. You are the salesman.
