Continued from Page 38 harvested later in the season can become water stressed when irrigation water is cut prior to harvest of an earlier maturing almond variety in the same orchard. “It’s an economic decision for a grower. If they can have a one-in and one-out harvest that beats the third flight of navel orangeworm with no tree stress that is an advantage,” Rothenberg said. Of the more than 1.1 million acres of almonds planted in California there are now an estimated 250,000 acres of self-fertile varieties. As almond acreage expands, it may become difficult to source enough bees for pollination, Rothenberg said. Self-fertile varieties may take off some of the pressure. BUILDING SUCCESS Shasta Variety Shasta, the newcomer with the self-fertile trait, is gaining in acres four years after the first commercial planting. Ron Boone of Burchell Nursery said growers who had their first harvest in 2018 reported good yields with third leaf blocks producing 1,500 pounds per acre. Boone said Shasta is precocious and the one million trees in the ground are expected to produce 20 million pounds of almonds when the trees reach maturity. Shasta was developed in the Burchell Nursery breeding program. Boone said Shasta seems to require less chilling during dormancy than Independence and leafs out earlier than most other varieties. Growers report this variety also shakes well, in shell crack-outs of 60-65 percent, a well sealed, semisoft shell, and large sized kernels that blanch well. Trees are medium size, somewhat vigorous, with a shape of semi-upright to spreading. When it comes to pollination, there is a range of conditions that dictate how many hives are necessary or if they are necessary to ensure good yields from of self-fertile varieties. BA2 var. (PP#28,466) OVER 1.5 MILLION TREES SOLD Self-Fertile Early and heavy production. One harvest!

Pollination No concrete determination on the number of hives necessary for successful pollination in a self-fertile almond orchard has been made said Tom Gradziel, a University of California (UC) plant geneticist who conducts research trials for the Almond Board of California. There are variables in pollination of self-fertile varieties. Some years there is consistency in setting fruit and other years not, Gradziel said. Independence has more of a track record than the newer Shasta, but many more years of regional trials are needed, he added. Gradziel said growers of the self-fertile varieties of almonds need to pay attention to flower structure, temperatures, wind and humidity during bloom and understand how those factors affect pollination. Keeping records of bloom time conditions can assist with tracking pollination success– or failure. Wind and Flower Structure The interaction of wind and the flower structure play a large part in burchellnursery.com 800 828-TREE Continued on Page 42 40 West Coast Nut May 2019
