The Irish Farmers' Association said falling yields of new crop potatoes because of late planting and lack of fall could result in higher prices this year.
A spokesman said the second early crop British Queens yield was down by nearly 20 percent last season with yields much lower from early and main crop.
Late planting and near-drought conditions in the early growing areas in Louth and Wexford were cited as the reason. The price of new potatoes should fall as the main crop comes onto the market.
