Abstract
World walnut production is estimated at nearly a million metric tons (MT), most of which is in the Northern Hemisphere. The most important producing countries in 1997 were, in thousands of MT, China (240), the United States (209), Turkey (115), Iran (89), Ukraine (77), Yugoslavia (25), India (26), France (23), Greece (20), Bulgaria (14), Italy (12), Chile, Austria and Germany (13), and Spain, Belarus and Argentina (9). Total production has been estimated in Europe, Asia and North America to reach 324, 501 and 227 thousand metric tons respectively (FAO, 1997). Total World export reached 197.4 thousand MT, 102 from the United States, 54 from China, 15.3 from France, 15 from India, 1.1 from Turkey and 1 from Italy. The E.U. countries import 75% of the U.S. in-shell walnut production. The United States exports walnut to the E.U., Japan and other countries in roughly equal amounts (Hutin, 1996). These data emphasize the importance of the world walnut industry.
