Fruits and vegetables have been identified as potential production alternatives to use available farm resources. Several "market window" studies have been undertaken to evaluate such feasibility. These state and regional studies are analyzed and compared to identify underlying assumptions and methodologies. Recommendations of the studies are evaluated on an aggregate basis and limitations of the market window technique are identified and discussed. The technique was judged to be useful in planning because it involves consideration of potential costs to be incurred, markets to be evaluated, and price expectations for the various commodities considered.
