Unlike the jicama plant, the ahipa plant is small, nonclimbing, fast maturing, and unaffected by daylength.3 Its rapid growth and low, sometimes dwarflike habit make it well suited for large-scale commercial cultivation. Ahipa could therefore be the key to a vast new root crop, even for temperate regions.

In the United States (thanks largely to a growing Latin and Oriental population) ' jicama now appears regularly in supermarkets coast to coast.

The starch of jicama is easily digestible.6 The protein content on a dry matter basis is higher than that of other root crops, but fresh tubers have a low protein content because their moisture content is extremely high. 6 Approximately 80 percent of the starch particles are below 5 microns in diameter, and after a period of 16 hours in the digestive tract, 75 percent of the starch has been metabolized by glucoamylase as against 40 percent of the starch from sweet potato.

The materials collected should be made available to institutes that deal with crop development and mutation genetics.9 Special 7 By analogy with jicama, the insecticide is almost certainly rotenone. ~ A biosystematic research project examining the potential of the genus is currently being carried out at The Botanical Laboratory, University of Copenhagen, and The Botanical Institute of Crop Husbandry and Plant Breeding, both at the Royal Agricultural University, Copenhagen.

Trials of spacing, fertilization, pest control, irrigation, and other cultural requirements are needed, with particular attention to the effect of intensive management on the culinary quality. High moisture content makes ahipa tubers shrivel and lose condition more quickly than other root crops.
