OCA, ULLUCO AND MASHUA
Oca (Oxalis tuberosa) Oca produces the second most widely cultivated tuber after potato. It is hardy and frost resistant, with long, cylindrical tubers from white to deep grayish purple. High in protein, with a good balance of amino acids, it is also a good source of fiber, and high in antioxidants.
Ulluco (Ullucus tuberosus) Ulluco is the most widely recognized and commercially viable of the ARTC’s, popular for its taste. It is easy to grow, frost resistant, and is moderately drought resistant, although the plant prefers soils that are rich in organic matter.
Mashua (Tropaeolum tuberosum) Mashua is one of the highest yielding Andean tubers (yield can reach 70 tons per hectare) and one of the easiest to grow. It thrives on marginal soils, develops rapidly, and competes successfully with weeds.
