Record 2016 California Walnut Crop09/06/2016
California English walnut growers are poised to produce about 670,000 tons of nuts, up 11 percent from last year’s production of 603,000 tons, according to a survey by the National Agricultural Statistics Service (NASS) at Sacramento.
NASS’ 2016 Walnut O.M. Survey utilized a total of 729 blocks with two sample trees per block. Survey data suggested average nut set at 1,406 per tree, up 11 percent from last year’s 1,272.
In the survey, 2016 statewide percent of sound kernels in-shell was 98.7 percent with the in-shell weight per nut at 21.6 grams. The average in-shell suture measurement was 32.2 millimeters. The in-shell cross-width measurement was 32.7 and the average length in-shell was 38.2 millimeters.
All sizing measurements were below average levels since 1985.
NASS says the 2016 walnut season began with fair amounts of winter moisture and adequate chilling hours. Weather during the walnut bloom was average – a mix of ideal days and others with stronger winds and wet weather.
Rain during the spring moths increased blight chances.
