ABSTRACT
Labor profiles are built up from the components of operational sequence, timing aid work rates, or from experimental and trial farm records where new operations, or revised sequences and crop calenders, are implicit in the new practices. Existing and potential food enterprises compete to satisfy farmers’ food requirements, in the same supply pattern as the existing system; and cotton activities compete to maximize the productivity of residual family labor resources and the use of 400 shillings’ capital for labor buying. The term “complexity” has a restricted meaning, referring to the number of changes in the timing of labor inputs between monthly periods as a consequence of the new activities in the solution. The labor profiles for subsistence crops and cash crops in the existing system are related to those derived from the acreage values of the solution.
