Production Research
For more than 50 years, continued investment in production research has increased profitability of walnut production.
The Board and Commission continue to work on your behalf. The CWB provides funding and strategic direction on walnut production and post-harvest research designed to help support the industry by improving crop health, yields, and food safety. The California walnut industry includes more than 4,500 growers and nearly 86 handlers. If you are interested in finding or contacting a supplier, please refer to this list.
More than 99% of the walnuts in the U.S. are grown in the fertile soils of California’s Central Valley. And this is made possible by the efforts of the 4,500+ family farms that have been growing walnuts of the highest quality for over a century.
California walnuts supply three-quarters of the world’s walnut trade. This can be attributed to not only the growing popularity of walnuts, but also the quality consciousness of the walnut handlers that has helped California walnuts become more sought after by consumers.
