The 2017/18 California walnut crop is projected at 650,000 tons (in-shell weight), down 5 percent from last season’s record 686,000 tons. This year’s hot summer in the Central Valley stressed some groves, and yield may fall below 2.0 tons per acre as a result, but a 6 percent increase in acreage will help hold this season’s production as the state’s second largest.
