ABSTRACT
Ulluco originated in the Andes Mountains in Peru, Bolivia and Northern Argentina. Primarily, it was found in Peru, Bolivia, Ecuador and then to a lesser extent in Colombia, Venezuela, Argentina and Chile. Ulluco, commonly known as papa lisa, olluco, or melloco, is very similar to the potato but not a close relative. All parts of the plant are edible at all stages of growth but tuber is the primary edible part used as food. Ulluco tubers are known to contain high levels of protein, carotene and calcium. The high level of ascorbic acid is also noteworthy. Its leaves are rich source of carotene and calcium. Ulluco is grown as an annual crop, though it is a perennial herb with a small number of 20 to 30 cm high, erect stems and fibrous roots, some of which are thicken at the end and produce tubers.
