"The pressure on, demand for food by rapid growth of human population, stressed the importance of tropical root and tuber as non-conventional food in the diet, especially of lower income groups in developing countries. These root and tuber crops include: Cassava and sweet potato (root tubers); aroids, yam, coleus (stem tuber), which are considered as staple foods for the tropical and subtropical regions like Africa, Caribbeans, South America, India and South East Asia. The tropical root and tuber crops have, within the past decades, increased in both local and international importance by the research workers, agriculturists, various agriculture colleges and institutions. The book includes various aspects like origin, geographical, distribution, cytogenetics, important strategy, physiology, biotechnology methods for improvement, microbial system, agro techniques, water management, diseases, insect-pest, chemical composition, toxic principles, utilization, post harvest deterioration, marketing and trade and selected references for each crop etc." (jacket)
