2014 California walnut production is forecast at a record 545,000 tons, up 11 percent from last year’s production of 492,000 tons.

Despite a lack of chilling hours and the California drought, the 2014 walnut crop topped the half-a-billion ton level. Growers used surface water where available and groundwater when necessary to provide adequate water to the trees.

Weather conditions during the growing season were mild which benefitted the crop. 

Walnut quality is excellent with low disease and insect pressures. 

Overall, the 2014 crop is developing faster than last year and an early harvest this fall is expected.
