Alfalfa Projects

340-Alfalfa Variety Evaluation in Mountain Valleys of Northern California

Principle Investigator: Dan Putnam, Extension Agronomist, Dept. of Plant Science, UC Davis; Craig Giannini, UC SRA, UC Davis

340

 

  • 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

Principle Investigator: Rachael Long, Farm Advisor for Field Crops, Pest Management,

345-Cutting Schedule Effects on Reduced Lignin & Conventional Alfalfa

Principle Investigator: Dan Putnam, Extension Agronomist, Department of Plant Sciences, UC Davis

345

 

  • 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

366-Clover Root Cucurlio Management in Alfalfa Production

Principle 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
    CRC
    of CRC biology and life history and of the conditions where CRC may be problematic, thus improving the timing and effectiveness of management decisions.
  • 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.

397-Alfalfa Germplasm Evaluation-Fall Dormancy

Principle Investigator: Charles Brummer, Director, Plant Breeding Center, UC Davis; Dan Putnam, Extension Agronomist, Department of Plant Science, UC Davis.

DSC02899

  • 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.
