Relative performance of alternative farming systems was studied by applying residual income measures such as gross margin, net farm income and management income. The results showed that gross margin per Taka of variable cost varied sufficiently among enterprises within each farming system. Among the individual enterprises within the crop component, vegetabale and fruits gave highest gross margin per Taka of variable cost in all the systems of farming. Among the components of the whole farm business, fish component had the highest gross margin per Taka of variable cost in all the systems of farming. Net farm income was reasonably high for all the systems. Except for the Crop-Cattle-PouItryFish system, all the systems earned negative management income. However, return to operator's labour and management was positive for all the systems. In view of the fact that many of the farm fixed resources have lower opportunity costs, it may be plausible to assume that farmers might be content with whatever positive return they earn over their composite input "labour and management".
