Approach: A linear programming model and a fuzzy multi-objective fractional programming model were applied and then these models were compared. Results: Result of study showed ratio of net return into consumption of inputs and Ratio of consumption of inputs into area under cultivation are improved with applying of FMOLFP. Conclusion: FMOLFP models can be used as an effective tool for optimal cropping pattern when in addition to economical goals, environmental goals are noticed. Managers and decision makers can apply these models for optimization of ratio of objectives.}, journal = {American Journal of Agricultural and Biological Sciences}, publisher = {Science Publications} }
