ABSTRACT
This study derives from a concern with the contemporary situation in farming system studies where problems arise when costs are to be allocated to specific crops in a mixed-cropped enterprise. The root lengths of crops were utilized to derive models for cost allocation. It is conceived that if one could compute the ‘area of influence’, or the ‘the lateral nutrient extraction zone’ of each crop in a farm plot, then the area occupied in the whole plot by the specific crop could be estimated. The portion of the farm plot occupied in the whole plot by the specific crop could be estimated. The portion of the farm plot occupied by a given crop relative to the total area is therefore utilized to allocate the costs of joint inputs and operations. Where crop production is stereotyped along sex lines as in the study area, such models would be very valuable in the analysis of inter/intra household relationships in farming.
