Commercial production

The cultivation requires a tropical climate that does not see much frost. For high-quality vegetables, sandy loam soil with good drainage is required. This plant takes anywhere from 4 to 8 months to produce roots and is then harvested by hand or by plowing. Freshly harvested jicama is the most flavorful, as this root ages rapidly and quickly loses its flavor.

Yam bean must be peeled before serving. It has a crunchy and juicy texture, as well as a mildly sweet taste. Fresh jicama can be stored in a cool, dry place for up to three weeks. When already sliced or cut, this food should be refrigerated.
