The mashua (see below for other names) is a perennial plant grown in the Andes for its edible tuber, which is eaten as a root vegetable. It is a major food source there. The tuber is rather peppery in flavor when raw, but this quality disappears when cooked. It is related to garden nasturtiums, being of the Tropaeolum genus, not to be confused with the genus Nasturtium.

Cultivation

The plant grows vigorously even in marginal soils and in the presence of weeds. It is also well-adapted to high-altitude subsistence agriculture, and gives high yields; 30 tonnes per hectare are yielded at a height of 3000 metres, but up to 70 tons per hectare have been produced under research conditions.

Its extraordinary resistance to insect, nematode, and bacterial pests is attributed to high levels of isothiocyanates. In Colombia, it is planted as a companion crop to repel pests in potato fields.
