A study is presented which assesses agricultural production in a Purchase Land area over a seven-year period and tries to identify certain socio-psychological and other variables which might be acting as constraints on farming behavior in terms of change. A survey was conducted of the whole population of 198 resident farm families; it included six questionnaires. Subjects covered included agricultural production and farm information, mass media contact, personal and family characteristics, social participation, extension contact, media exposure, farm practice adoption and farmers' opinions on farming and extension. The investigation confirmed that exposure to all sources of information correlated with farmer efficiency. Data analysis indicates that sound technology and well-organized extension and educational efforts coupled with financial assistance will increase farmer response to extension. (Author/CK)
