CDFA grant helps analysis to optimize water use for iconic California crop
California growers, who account for greater than 90% of avocado manufacturing within the U.S., will quickly be getting some assist in weathering the intense fluctuations of local weather change.
Ali Montazar, a College of California Cooperative Extension irrigation and water administration advisor, lately acquired a grant to develop instruments and methods that optimize growers’ irrigation practices throughout Southern California – the state’s avocado belt. California avocados are valued at greater than $411 million, in accordance with the Nationwide Agricultural Statistics Service.
“This area faces unsure water provides, obligatory reductions of water use, and the rising price of water – whereas environment friendly use of irrigation water is likely one of the highest conservation priorities,” Montazar stated. “Water is probably the most critically necessary enter to avocado manufacturing.”

Montazar might be conducting discipline experiments in six industrial fields of Hass avocados, positioned in San Diego, Riverside and Orange counties, in collaboration with the California Avocado Fee and supported by a California Division of Meals and Agriculture Specialty Crop Block Grant.
On the California Avocado Fee’s suggestion, Orange County was added to the examine to raised seize the vary of climates and cropping techniques throughout the area, Montazar stated.
He hopes to develop “crop coefficients” that avocado growers can use to find out the optimum irrigation for his or her crop primarily based on a bunch of things: soil kind and salinity, cover options, row orientation, slopes, soil and water administration practices, and extra.
“Growers are unclear on how a lot water the crop really wants underneath these situations,” Montazar stated.
He’ll incorporate information from the precise water use within the experimental orchards – together with data from the latest soil moisture and cover temperature sensors – to assist guarantee growers don’t under- or overwater their crops. Overirrigating contributes to a devastating illness, avocado root rot, attributable to the plant pathogen Phytophthora cinnamomi.
One other part of the grant helps outreach in disseminating these sources and finest practices to the broader agricultural neighborhood.
“Creating and adopting these instruments and data might have a major affect on water high quality and amount points and bolster the financial sustainability of avocado manufacturing not solely within the well-established manufacturing area of Southern California, but additionally in Kern and Tulare counties the place new avocado plantings are rising,” Montazar stated.
Preliminary findings and suggestions are anticipated on the finish of 2022.
