Info

Storage and transportIn the tropics and where refrigerated storageis not available, seed tubers should be storedunder diffuse light in order to maintaintheir sprouting capacity and to encouragedevelopment of vigorous sprouts. In regionswith only one cropping season per year andwhere storage of tubers from one season tothe next is difficult without the use of costlyrefrigeration equipment, off-season plantingmay offer a solution. Importation of seedtubers is common in these regions, but mayentail higher costs and risks of late deliveryand deterioration in tuber quality along themarketing chain.Ware potatoes should be kept at atemperature of about 6 to 8°C, in a dark,well ventilated environment with highrelative humidity (85 to 90 percent). Forprocessing purposes, such as the productionof french fries, storage temperatures mayrange up to 10°C to reduce the risk ofincreasing sugar levels, which areresponsible for a dark colour during frying.Potato darkening can also be caused by anexcess of nitrogen in the fertilizationformula.During transport of seed tubers and wareand processing potatoes, it is important toavoid bruising by reducing drop height,lining containers with rubber or other softmaterial, and avoiding extremetemperatures. Tubers should be protectedagainst unexpected rainfall and snow, whichcan occur at high altitudes.29GOODAGRICULTURALPRATICESAND POTATOPRODUCTION
