After struggling earlier in the year to stay ahead of constantly changing weather conditions and to complete their fieldwork in between rains, Tehama County walnut growers are finding the going much easier as the season winds down.

“This is one of the best walnut crops I’ve seen,” says Rick Buchner, University of California Cooperative Extension orchard farm advisor for the county.

Despite the variable spring, the trees hit a wide enough window of favorable conditions to set the nuts, he thinks.

Whatever the explanation, growers are now seeing what appears to be a good size, clean crop of decent quality, and prices remain strong.

Off year for Arizona pistachios

Arizona pistachio grower Steve Seplak expected his production would go down in 2011 — an off-year for the alternate bearing crop. He just didn’t expect it to drop as far as appeared likely in the early days of August.

One of about 30 pistachio growers in the Sulfur Springs Valley near Bowie, Ariz., he grows about 20 acres of pistachio trees in his SAS-Z Nuts orchard near Willcox, Ariz. Between the on-years and the lower-producing off-years, the trees yield an average of 1,850 pounds of nuts per acre annually. In a good year, that can reach 2,500 to 2,850 pounds.

Last year was an exceptionally productive one; his yields shot up to 3,550 pounds per acre. The weather may help explain that, he says.

“Winter before last, we had a lot of rain and a mild spring, and everything came out strong. Even the fruit orchard crops were out of this world.”
