Changes in the distribution of an agricultural commodity among quality classes may affect the total revenue obtained from a given quantity of product. Growers and marketing firms need to consider the best mix of qualities as well as the best level of output. This paper describes an approach to the empirical problem of selecting, from several alternative feasible mixes of qualities, the one which would yield the maximum net revenue. The paper focuses on a single attribute and a single commodity but the concepts and methodology used can be extended readily to other quality attributes and other commodities.
