SJC and Delta Field Crops Meeting Agenda

On Thursday, January 17th, I hosted the annual SJC and Delta Field Crops Meeting in Stockton, CA. I want to thank everyone who attended and provided feedback on the meeting. Your evaluations are critical and inform Cooperative Extension outreach efforts! The presentations from that meeting have now been posted to my website. I encourage you to reach out to the presenters with questions. Also available from my website are full reports of local research trials, including the Delta field corn variety trial. I will make an announcement here on the blog when new reports are available.
UC statewide specialists make their research results available through the Agronomy Research and Information Center (RIC) website. Please check the RIC for information on statewide trials in small grains, alfalfa, dry beans, and other field crops.
We hope you will find this information useful, and we hope you will share your feedback with us so that we may best serve your interests for research and outreach.
