World production of nuts and seeds

Data on world production of nuts and oily seed include the quantity that are planted, harvested and marketed some that were harvested and marketed from unplanted trees and estimates of those that were produced but not marketed. Many of the records are incomplete. Examples of unrecorded production are vast quantities of Brazil nuts are harvested from native trees in the Amazon River basin Persian walnuts

Some of the most productive trees and highest quality nuts come from small home orchards around the world. 

Data in Table 6.1 show the tonnage of nuts harvested during the decade between 1979 and 1989. There was an increase in tonnage of all tree nuts, including coconuts and palm nuts. 

Most nuts of the world come from areas where they are native. Brazil nuts come from wild trees in Brazil. Heart nuts, hickory nuts, butternuts and black walnuts grow in the Eastern United States in the foothills of the Appalachian Mountains where they are native. English (Persian) walnuts come from their native home of the Himalaya Mountains in northern India. They are also planted and grown in China, the United States, Turkey, Italy and France. Pecans are native to the southern United States west of the Mississippi River. They are grown in the southern United States from coast to coast.
