It’s important for growers who are producing for sensitive markets (those that reject GMO alfalfa) such as export or organic to produce non-GE alfalfa Hay. See PAPER on production of non-GE alfalfa – soon to be published in Crop, Forage and Turfgrass Management. Also, see PAPER on Sampling methods for low level presence.


Netafim is hosting a field day on Subsurface Drip Irrigation (SDI) concepts, components and management requirements.  Get a review of agronomic and cultural management practices for SDI alfalfa, and learn about rodent management planning to protect your SDI investment. Meet a successful SDI alfalfa grower and learn first-hand how he's increased bottom-line profits.


River Garden Farms is located on the corner of Highway 45 and County Line Road in Knights Landing. RSVP is appreciated for the lunch count.

2016 Russell Ranch Sustainable Agriculture Field Day

The 2016 Russell Ranch Sustainable Agriculture Field Day will explore research, farmers' practices and commercial products that aim for resilience in the face of drought, uncertain water allocations, and weather extremes. The Field Day will go from 8:00am - 1:30pm at the Russell Ranch in Davis. General registration fees are $10, students are $5, and farmers are free.

Contact Kate Scow, director of Russell Ranch at

8:00-12:00 Small Grains Field Day

Directions: Take 113 North of I80 in Davis, take the Hutchison exit, turn right at the first roundabout, left on the second roundabout, 1/3 mile down on the left, Agronomy Headquarters, Hutchison Road.

A newly published article reviews the differences between species and varieties of cool-season grasses grown under deficit irrigation. Twenty-five perennial grass species/ cultivars were evaluated under three irrigation regimes (fullseason irrigation, early cutoff, and mid-season cutoff ) over 3 year period at the Intermountain Research and Extension Center in the Klamath Basin, Tulelake, CA.

Forage grasses included: 10 tall fescue cultivars, seven orchardgrass cultivars, four bromegrass species (Bromus spp), three wheatgrass species, and festulolium.  These species differed in response to water deficits.

Which species appeared to be better under full and deficit irrigation regimes? 


2015 Western Alfalfa & Forage Symposium was held in Reno, Nevada 2-3-4 December, 2015 at the Silver Legacy Hotel. WE had a terrific and enthusiastic crowd, with a total of 570 attendees, and 71 exhibits.

This year we had a special focus on water and irrigation issues, but also plenty on pest management, economics, alternative crops, forage quality, and equipment. To see a complete schedule with Proceedings Papers, and Powerpoints and Videos of presentations, see:

2015 Irrigation Program & Workshop Videos and PDFs of workshop talks available here.

Field Day

Field Days

The Alfalfa & Forage Systems Workgroup periodically holds field days to discuss on-going research. We have archived some of the handouts from these field days. Please see below to view selected handouts, presentations, and information from our 2014-2015 Field Days:
  • Alfalfa/Field Crops Field Day in El Centro, 2015 was held on April 16, 2015 at the UC Desert Research and Extension Center in Holtville, CA in the Imperial Valley. Water and Pest Management were the focus of a field day. Topics of discussion included water issues with alfalfa and forages, as well as other agronomic crops.

  • UC Davis Alfalfa/Forages Field Day, 2015 was held at UC Davis on May 12, 2015. At this field day Farmers, PCAs, and CCAs toured research plots to discuss critical issues related to water and pest management. Visit the UCD Alfalfa/Forage Field Day page.

  • Kearney Alfalfa and Forage Field Day, 2015 was held at the Kearney Agricultural Research and Extension Center, on September 18, 2015 from 7:30 am - 1:00 pm. The alfalfa and forage field day at Kearney Agricultural Center featured a field tour and presentations on topics such as irrigation management, variety selection, and pest control. Visit the Kearney Field Day page.

  • Forage and Grain Sorghum Field Day & Workshop, 2015 was held at the University of California Desert Research and Extension Center in Holtville, CA, on September 30, 2015. Offered at this field day was a field demonstration and workshops focused on Forage and Sorghum.

  • El Centro Field Day, 2014: An alfalfa and field crops field day was held in El Centro, Imperial County on 17th April. Alfalfa drip irrigation, varieties, wheat, oilseed crops, and sorghum was featured. See PDF of the handouts here.

  • Davis Field Day, 2014: An alfalfa and grains field day was held on the UC Davis Campus on May 7th, 2014. It featured new research on measuring water use in alfalfa, drought response, weeds, aphids, pest management, low lignin trait in alfalfa. See schedule here.

  • Kearney Field Day, 2014: The alfalfa and forage field day at Kearney was held on September 12th. It featured a field tour and presentations on topics such as irrigation management, variety selection, and pest control.
