Costs of production for fresh potatoes will increase only slightly for 1982; substantially reduced seed costs should offset other operating cost increases. Processing potato costs should range from almost unchanged in the Red River Valley to a 4.2-percent increase in western Idaho. Central Wisconsin showed the lowest total cost for producing fresh potatoes, while Maine had a cost advantage over other producing areas for supplying fresh potatoes to northeastern U.S. markets. Eastern Idaho showed the highest cost per hundredweight for fresh potatoes. Washington's Columbia River Basin had the lowest cost for growing, harvesting, and storing processing potatoes, while the Minnesota/North Dakota Red River Valley had the highest. This study estimates costs for producing, storing, and packing potatoes in major U.S. production regions during 1980 and 1981 with projections for 1982.
