The USDA NASS California Field Office crop estimates, released last week, confirm expectations of the growing California walnut industry. As the 2010 harvest begins in California's Central Valley, NASS predicts the annual yield to be 510,000 short tons, demonstrating a record production that is 17 percent larger than 2009's crop of 437,000 and more than double the crop production from the year 2000. This year's estimate is to be confirmed in February 2011.

According to California Walnut Board member Jack Mariani, "This has been an excellent growing year — a nice wet winter and trees were strong and healthy. This estimated record crop along with the shortest carry-ins on record and vigorous consumer demand will help grow the industry."
