(Pachyrhizus erosus)

Jicama is a perennial nitrogen-fixing vine that reaches 10 m in length and is grown for the edible tuber. Jicama is also used as fodder, green manure, or cover crop. The tuber is edible and is mainly a starch/carbohydrate source, relatively low in calories. The leaves and mature beans contain rotenone, a natural insecticide.
