      A new alfalfa variety trial was planted in the fall of 1987to replace the previous four-year trial. The top varieties from the previous trial were placed in the new trial, along with new, promising varieties. A single year's data is insufficient to judge the performance of a variety during its useful years of production. The data simply indicate performance in their first year. Pioneer 5929, the variety that had the best overall yield in the previous trial (1), performed well in this trial as well. However, Mecca, a new variety from Plant Genetics, Inc., had the highest yield.

      For the past three years, ten alfalfa varieties have been grown and yields recorded. Yields in excess of 9 tons per acre were harvested in 1988 on 7 of the 10 varieties. Baron, a moderately nondormant variety, was the highest yielding variety for the three years, with an average yield of 8.9 tons per acre.
