ABSTRACT
Farm management economics makes its contribution through the existing extension services by identifying appropriate extension content. This chapter identifies the structure of the extension services and government policy on agricultural development strategy as important conditions molding the approach which the discipline must adopt. It deals with extension organization, for the investigational and planning sequences raise guidelines for mounting extension programs in the field, and outlines the responsibilities of the usual three levels of the extension hierarchy in the field: the contact staff, the supervisors, and the local organizer. The investigational phase identifies complementarity between crops in the system, particularly subsistence crops and the various roles for each crop. The planning phase identifies activities with low productivity at critically busy periods of the season. The progression of changes provides the content for extension effort on the farms of adopters identified by their willingness to try out the initial innovation.
