2020 N. Sacramento Valley Almond Research Reports

Mar 8, 2021

Hi Folks - 

In January, after my variety evaluation presentation at the Sacramento Valley Almond Meeting, several people inquired about the final 2020 yields for the 30 experimental varieties at the UCCE almond variety trial held at the Chico State Farm. The folks at UC Davis triple checked the numbers, and confirmed the sky-high yields (e.g. 4,500 lbs./ac for Nonpareil). I will also be sending out my other 2020 reports for walnut and prune research, so that you know about the UC research going in the North Sacramento Valley.

Do you know folks who are missing news from UCCE because they aren't signed up for the electronic newsletter? Be sure to let them know to sign up at: ucanr.edu/buttenews, ucanr.edu/glennnews, or ucanr.edu/tehamanews. If you did not receive these reports, be sure to email me at lkmilliron@ucanr.edu and sign up via an e-newsletter link above.  

As always, the latest orchard information can be found at: sacvalleyorchards.com. I hope you are also listening to the weekly podcasts from Growing the Valley.  

The best way to contact me is to please call my cell (530) 828-9666. If I don’t answer, be sure to leave a voicemail, to push yourself to the top of my agenda!  

Cheers, 

Luke
