Abstract: | We describe the traditional production system of the root of jalapa, Ipomoea purga, in Xico, Veracruz, Mexico. The results are based on open interviews with the producers to gather information on the development of this crop in the area, and observation of the production system. The production cycle is carried out between July and February. We found that seed scarification is the key to the success of the productive system, obtaining a maximum of 95% seed germination in eight days. This activity, as well as seed collection and the driving of stakes into the ground for plant support, requires a considerable input of man-power. It is an intensive farming process, the cultivated area per farmer varies between 300 m2 and 1000 m1, and the yield ranges between 1.5 and 2.7 tons per hectare of fresh roots; when dried they lose up to 75% of their weight. Smoke-dried roots are exported for sale. |
