توضیحاتی درمورد کتاب به خارجی

London: Leonard Hill [Books] Ltd.; New York: Interscience Publishers Inc., 1962. — 474 pp. — (World Crop Series).
ISBN-10: 0249388596.
ISBN-13: 978-0249388596.
The need for a book on alfalfa, in all its aspects as an important world crop, has been evident for a considerable time. Stewart's Alfalfa-growing in the United States and Canada was published in 1926, and has, ever since, been the latest book on the subject for readers of English. Yet its coverage was largely confined to North America; and it is scarcely necessary to emphasize the spectacular advances which have occurred since that time. Alfalfa has almost certainly been the subject of more research than any other single forage crop, and possibly of more than all other forage crops combined; consequently, an extensive literature has accumulated that is to be found only in scientific journals and government bulletins.
It has not been easy to survey this literature and analyse the information contained in it, and, at the end, the author is left with persistent doubts as to the adequacy of his efforts. But, probably, English-language publications have been fairly surveyed, and fortunately they represent the major areas where research has been most active. However, language barriers have prevented similar detailed attention to work done in western Europe, the Soviet Union, and South America, so that some important research has doubtless been overlooked or has received inadequate treatment.
