340-Alfalfa Variety Evaluation in Mountain Valleys of Northern California
Principal Investigator: Dan Putnam, Extension Agronomist, Dept. of Plant Science, UC Davis; Craig Giannini, UC SRA, UC Davis
- Evaluate certified cultivar differences in alfalfa forage yield, quality, and persistence, and to communicate these results to clientele
- Develop and provide forage yield and performance data on alfalfa experimental germplasm to public and private alfalfa scientists
342-Improved Management of Alfalfa Weevil in California to Facilitate Water Quality Protection and Crop Sustainability
Principal Investigator: Rachael Long, Farm Advisor for Field Crops, Pest Management,
345-Cutting Schedule Effects on Reduced Lignin & Conventional Alfalfa
Principal Investigator: Dan Putnam, Extension Agronomist, Department of Plant Sciences, UC Davis
- Determine the effect of a 3-cut versus 4-cut harvest schedule on rate of forage quality change of genetically engineered low lignin alfalfa compared to the null that does not carry the trait and compared with a commercial standard
- Determine the appropriate cutting management schedule for low-lignin alfalfa compared with conventional non-genetically engineered alfalfa
360-Resiliance of Alfalfa Cultivars to Variable Environments
Principal Investigator: Charles Brummer, Director, Plant Breeding Center, UC Davis.
- The main goal of this project is to develop methods to measure and understand the resilience of alfalfa cultivars to abiotic stresses, to: a) identify cultivars with superior resilience, b) identify alfalfa plant
In California, we will conduct field experiments for Objective 2:
- To empirically measure resilience of alfalfa cultivars to water and cold stresses in controlled replicated field experiments across the USA, and identify plant traits associated with resilience.
366-Clover Root Cucurlio Management in Alfalfa Production
Principal Investigator: Rachael Long, Farm Advisor for Field Crops, Pest Management, UCCECapitol Corridor, Woodland, CA.
- Track the activity of CRC life stages during the season to improve our understanding
- Evaluate biological and chemical pesticides for CRC suppression given that there are no registered soil active products.
- Evaluate alfalfa varieties/lines that show resistance toward insect pests on CRC feeding and oviposition.
- Collaboratively conduct multistate Extension programs that help alfalfa growers understand CRC activity and adopt CRC management strategies.
386-Evaluation of New Herbicide for Between Cutting Weed Control in Alfalfa
Principal Investigator: Thom Getts, UCCE-Lassen.
- Evaluate the crop safety of various herbicides applied to alfalfa between
- Evaluate weed control efficacy of various herbicides applied to alfalfa between cuttings, including multiple rates of herbicide CNV2243.
387-A RR Alfalfa Injury
Principal Investigator: Tom Getts, UCCE-Lassen.
- Is pseudomonas syringae responsible for alfalfa injury?
- What agronomic factors can reduce the risk of this injury?
387-B RR Alfalfa Injury - What's Happening?
Principal Investigator: Rob Wilson, Center Director/Farm Advisor, IREC.
- Collaborate with Debby Samac with USDA-ARS to analyze alfalfa samples from several study sites to determine levels of syringae
- Better document the injury and yield reductions associated with glyphosate at different growth stages to determine Roundup application times that cause the most and least crop injury.
- Determine if suppressing P. syringae populations on alfalfa plant tissue with copper bactericides and mancozeb influence crop injury following glyphosate applications and frost.
397-Alfalfa Germplasm Evaluation-Fall Dormancy
Principal Investigator: Charles Brummer, Director, Plant Breeding Center, UC Davis; Dan Putnam, Extension Agronomist, Department of Plant Science, UC Davis.
- To develop a measurement method to assess dormancy in swards.
- To evaluate fall dormancy of the standard check cultivars and selected other modern cultivars in both swards using the new protocol and in spaced plants using the current protocol.
