دانلود رایگان کتاب Sweet Potato research and Development for Small Farmers
Sweet potato is an Asian crop in spite of its new world origin. Over 80 percent of the world’s root crop production is now in Asia and Oceania.
Sweet potato is an important staple and emergency food in many countries, especially for the poorest the resource poor farmers and the urban poor. It is also a vegetable, a snack food and confectionery item in most countries. Throughout Asia, it is an important ingredient in animal diets (particularly for pigs) on many small farms. The Iowly sweet potato is starting to increase in status and is finding a role in the diets of the urban elite, and is now being used more for processed products. These are some of the results that are presented in this publication of the proceedings of the Sweet Potato Workshop held at the Visayas State College of Agriculture (ViSCA) at Baybay, Leyte, the Philippines, on 20-24 May 1987. This workshop, the second International Sweet Potato Meeting held in Asia, is unique. Representatives from ail the top sweet potato producing countries were present, particularly China and Vietnam, the top two producers which had been absent in previous meetings. In addition to the scientific program, which covered recent advances in breeding, diseases and pests, chemical composition, storage, processing, and marketing, the program also focused on the problems and research needs of the small farmers who produce most of the sweet potatoes in Asia. In addition, considerable discussion on future networking and collaboration in research and training ensued.
