Ahipa (Pachyrhizus ahipa)

Perennial
Dolichos ahipa.
Common Name Latin Name Plant Family
Ahipa
Pachyrhizus ahipa
Leguminosae

The plant contains rotenone, the active ingredient in the insecticide ‘derris’, and it has the potential to be used as an insecticide[200]. Derris is a relatively safe insecticide in that it does not affect warm-blooded animals and also breaks down into harmless substances with 24 hours of being used. It does, however, kill some beneficial insects and is also toxic to fish and amphibians[K].

  • Medicinal Use

    None known

  • Edible Use

    Root – raw or cooked[2]. Thirst quenching and nutritious with an easily digested starch[196]. The root is slow to discolour and remains crisp after slicing so it is often used in green and in fruit salads[196].

    Young seed pods – cooked and used like French beans[1, 46, 61]. The pods must be thoroughly cooked in order to remove the toxic principle rotenone[200]. It is thought that some varieties might be free of rotenone and their mature seeds could therefore be used as a protein crop[196].

  • Cautionary Notes

    The seed and green parts of the plant contain an insecticide (probably rotenone) and might be poisonous to people[196].

Cultivation & Habitat

Pre-soak the seed for 12 hours in warm water and then sow in early spring in a warm greenhouse. Germination should take place within 2 weeks. As soon as they are large enough to handle, prick out the seedlings into individual pots of rich soil and grow them on fast. Plant them out after the last expected frosts. Give the plants some protection, such as a cloche, until they are growing away well. Division of the root tubers in the autumn. Store the roots in a cool but frost-free place over the winter, planting them into pots in the greenhouse in early spring and planting them out after the last expected frosts. Give the plants some protection, such as a cloche, until they are growing away well. Cuttings.
Prefers a light rich well-drained sandy soil[196]. Sometimes cultivated for its edible root in the Andes[196], this plant is not frost hardy but could possibly be grown as a summer crop in cool temperate zones. There are some named varieties[196]. When grown for its root the flowers should be removed, this is thought to increase the size of roots by up to 100%[196]. The plant is day-neutral and so is much more likely to produce tubers in this country than the related jicama, Pachyrrizus tuberosus[196]. It has produced good yields when grown in a greenhouse in Denmark[196]. A faster-maturing plant than the jicama, it flowers in about 10 weeks from seed and the root is harvested after 5 – 6 months[196]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200].
