To compare university alfalfa variety trial yields, visit www.uwex.edu/ces/ag/alfalfa. This University of Wisconsin Forage Research and Extension site lets growers look at yearly research trial yields of a number of varieties from 11 states and a Canadian region.

The database compares two varieties at a time, tells the stand age, the number of trials, trial mean and variety yields and a percent of mean. Side-by-side comparisons are offered where both varieties were grown in the same study.
