2019 ‘Off’ Year Pistachio Crop Looks Above Average

Adequate chill over the winter in all California growing regions, plus new acreage coming into production are expected to bring in a harvest that is estimated to be in the 700-850 million pound range. That is not close to record 994 million pounds of pistachios harvested last year in California, Arizona and New Mexico, but is very good production for this alternate bearing crop, said Richard Matoian, executive director of American Pistachio Growers. Increased Acreage Matoian said he is comfortable with the 700-850 million pound range that was forecast at the International Dried Fruit and Nut Congress in May. The...

Getting the Most Out of a Golden Hills Pistachio Harvest

Prior to the release of the cultivar Golden Hills, pistachio growers in the San Joaquin Valley (SJV) of California were accustomed to harvesting a single female cultivar named Kerman. Since Kerman was the only female cultivar that most growers had any experience with, the way Kerman was harvested became synonymous with how pistachios, in general, should be harvested. However, different cultivars have “individualities” that should be addressed to make a harvest more successful. What makes for a successful Kerman harvest is not, necessarily, that which makes for a successful Golden Hills harvest and vice versa. Although Golden Hills was released...

Supplemental Pollination Shows Potential

Every year in early February, University of California Cooperative Extension (UCCE) farm advisor Elizabeth Fichtner said, she gets calls from anxious almond growers about using supplemental pollination in their orchards to ensure profitable yields. Challenging Weather Growers have concerns about almond pollination, she said, when the extended weather forecasts call for cool, cloudy and rainy days. Their bee supplier may not be able to deliver adequate numbers of hives or hive strength may be an issue when there are fewer hours that bees will fly. This year was one of those challenging times of cool, wet weather that is not...

Expanding your NOW Toolbox

By Kathy Coatney | Editor

Overall the first flight of navel orangeworm (NOW) has been lighter than normal this year. This could be attributed to relatively low 2018 damage levels, especially in pistachios, and the cooler, wetter weather during the 2019 spring. “If we get really warm sustained temperatures early in the spring, navel orangeworm wakes up early and becomes active,” according to David Haviland, University of California Cooperative Extension (UCCE) entomology farm advisor for Kern County. But this spring was cooler, overcast and wet, so the first flight was more spread out than normal, Haviland said. NOW Damage “Damage last year in almonds was...

Distribution Uniformity:

By Dani Lightle, UC Cooperative Extension Orchard Systems Advisor, Glenn, Butte & Tehama Counties

What is Distribution Uniformity? Distribution Uniformity (DU) is a measure of how uniformly water is being applied across the orchard, or whether certain parts of the orchard are receiving more water than others. It is a measure of the irrigation system. DU is a different measure than irrigation efficiency, which is a measurement of how well the applied water matches the crop water requirements. Irrigation efficiency is a measurement of how well you—the irrigator—applies a correct amount of water at an appropriate frequency. However, it is impossible to have a high irrigation efficiency without also having high distribution uniformity
