Follow the link below to access everything you need to know about alfalfa variety selection. There is an article describing what to look for in an alfalfa variety as well as information on the pest and disease resistance characteristics of commercially available varieties. In this area, growers typically plant alfalfa varieties with fall dormancy ratings from 7-9. Recent results and historical data from variety trials conducted throughout California are also available at this site. The most recent report includes data from the 2010 trials. If you are a grower in the Central San Joaquin Valley and want to grow alfalfa on a sandy loam soil, pay particular attention to the results from the Kearney Ag Center. If you are on a heavier clay loam soil, the results from the West Side Research and Extension Center will be most appropriate. Don’t rely on data from a single year; look at performance over 2-3 years and select from the group of top performing varieties.
