Plant a nondormant variety with a dormancy class of 8, 9, or 10 for the low elevation deserts. Choose a variety with appropriate pest resistance characteristics. Test new varieties in strips or small areas on your farm. Do not plant more than 25% of your acreage to a new variety. Use certified seed. Obtain "Nondormant Alfalfa Varieties for Arizona, 2001" from your local Cooperative Extension office for pest resistance characteristics and yield trial results.
