What: Research plot tours and discussions with researchers about recent observations and up-to-date knowledge about production issues in field and forage crops

Who: Growers, pest control advisers, crop consultants, allied ag professionals, researchers, and anybody interested in San Joaquin Valley agricultural production are welcome to attend.

Continuing education: 

3.5 hours of Certified Crop Adviser (1.0 Soil & Water Management, 1.5 Integrated Pest Management & 1.0 Crop Management) have been applied for.

1.0 hours of CA Dept. of Food and Agriculture Irrigation and Nitrogen Management Training Program have been applied for.

1.75 CA Dept. of Pesticide Regulation "Other" hours for PCAs, QAC/Ls, and PACs have been applied for.

Thank you to our sponsors:

BASF, CA Dairy Research Foundation, FMC Corporation, and Irrometer generously sponsored this field day, and we're grateful for the support.

In 2024, UCCE began evaluating garbanzo varieties in Central Valley regional trials. In a San Joaquin County commercial field, we evaluated six advanced lines from the UC Davis garbanzo breeding program and two standard varieties (UC 27 and Sutter). The soil types at the trial site were Jacktone and Galt clays, and the soil temperature was approximately 63°F at the time of planting. Due to wet spring conditions, planting was delayed until March 15^th. Each variety was planted across four 40-inch beds (two rows per bed), on an average plot length of 884 feet. Planting depth was 1.5 inches, and the seeding rate was approximately 85 pounds per acre. An industry-standard fungicide seed treatment was applied to the seed before planting. Fertility and pests were managed by the grower in the same manner as the field, where the field variety was UC 27 and the previous crop was silage corn. Preplant herbicides were applied (Goal, Dual, and Chateau), but otherwise, the field received no other pesticide or fertilizer inputs. The field was irrigated one time at flowering.

This was a non-replicated evaluation; therefore, no statistical analysis is presented (Table 1). Stand counts were made approximately two weeks after planting on April 9^th. The stand was assessed as the number of plants per two-foot length. Twelve replicate counts were averaged. In early May, we observed that Sutter and advanced lines 102, 104, and 110 had slightly earlier flowering than UC 27 and advanced lines 94, 95, and 96. We are interested in knowing whether the advanced lines have tolerance to Fusarium wilt and Ascochyta blight, but no diseases were observed at this location.

We harvested on July 25^th. The plots in their entirety were combined and weighed. At harvest, the grower observed that lines 104 and 110 had an upright growth habit that made them easier to harvest. We measured harvest moisture on three subsamples, which were averaged for the summary table below, and we evaluated 100-seed weight as a measure of seed size, averaging five subsamples. In previous evaluations of these advanced lines at UC Davis, they have had higher yield and seed size than the industry standard varieties, and that held true at the San Joaquin County site this year.

We would like to thank the cooperating grower and bean warehouse; the CA Crop Improvement Association for funding regional trials; and the CA Dry Bean Advisory Board for assistance with statewide research prioritization and assistance with outreach.

We hope to see you next Thursday at the Field Day! 

UC Davis and UC Cooperative Extension will host the UC Dry Bean Field Day on Thursday, August 15, 2024 from 9:30am to 11:45am. The field day will begin at the Agronomy Field Headquarters (2400 Hutchison Drive) on the UC Davis campus. From the Agronomy Field Headquarters, follow the UCCE sandwich board signs to the field location. Look for the pop-up tents. The agenda is pasted below, and a downloadable version is attached to the bottom of this post. DPR (1.0 of Other) and CCA (1.0 Crop Management, 1.0 Pest Management) continuing education credits have been approved for this meeting. Light refreshments will be provided. Thanks for your interest, and we hope to see you at the field day!
