The Korea Rural Economic Institute forcasts a rise in potato prices in April, with wholesale prices expected to range from 70,000 to 75,000 won for 20 kg, marking a 4-12% increase from April of the previous year and a 27-36% increase from the average price over the past three years. This increase is due to a potato shortage and a predicted decrease in shipments, but the rise in prices may not be significant as spring potato production is expected to increase in April. The high prices are also attributed to the poor quality of some potatoes shipped this month due to low temperatures during the growing season, and the decrease in potato production in the United States.
