The authors would like to clarify that the USDA AMS potato prices used to calculate revenue and profit in their paper are in dollars per 50-lb units rather than dollars per hundredweight. Since the field trial yield data presented are in hundredweight, the prices used are effectively cut in half without explanation. However, dividing by two provides an approximation of grower returns. Potato cost and return studies typically scale shipping point prices to reflect returns to growers net of storage and packing costs paid to packing houses. (See https://www.uidaho.edu/extension/food/idaho-agbiz/crop-budgets, and https://coststudyfiles.ucdavis.edu/2024/05/10/23PotatoFreshMktKlamath-Final.pdf for examples.) The estimates presented in the paper (including revenue, ROVCs, and costs) remain unchanged.
