英文摘要	Ugandan farmers preferred vine cuttings from sweet potato (Ipomoea batatas (L) Lam.) plants maintained during the dry season in a swamp or by irrigation as planting material rather than cuttings from volunteer plants growing from unharvested roots. The latter were late and weevil-infested, though readily available. To improve their earliness, roots planted 5, 10, 15, or 25 cm below ground at the start of the dry season were watered from 5 or 10 weeks before the start of the rains. Only those planted 10 cm deep emerged satisfactorily; those watered for 10 weeks produced more vines. To improve survival, roots were stored under various conditions before planting and watering: roots stored in dry sand in a roofed building survived especially well and sprouted prolifically, producing many cuttings. This method of producing vine cuttings, called the Triple S method, was validated by farmers in the Lake Zone of Tanzania, which has a harsher climate than Uganda. In addition to providing farmers with ample early and healthy planting material for little and infrequent watering, it provided convenience and ownership.
