Economies of size for Maine potato packing plants
Maine has long been known as a major potato producing state. Since 1920, ten to 15 percent of the total United States potato production has been produced in Maine. Maine is classed as a fallcrop potato producing state, with most of the crop being placed in storage at harvest and then removed from storage and prepared for market during the 7-9 months following harvest. Most of the potatoes produced in Maine are, and have been, marketed as tablestock (fresh) potatoes. In recent years, about 53 percent of the sales have been as tablestock, with about 38 percent marketed to processing plants and starch factories, and nine percent marketed as seed potatoes.
