Varieties are grown in replicated plots at each location. These plots are handled so that the factors affecting yield and other characteristics are as nearly the same for all varieties at each location as is possible. Bromegrass is generally grown for hay in mixture with alfalfa, or is used as pasture in mixture with other grasses and legumes. Varieties can be classed as southern, intermediate, and northern types. Varieties of the southern type may not be higher yielding, but are generally less susceptible to leaf diseases and earlier in maturity than northern types.
All varieties are winter-hardy.
Performance in Trials Locations where bromegrass trials were conducted for this report. Varieties are currently being evaluated in pure stands at Minnesota experiment stations. Nitrogen was applied at all locations in early spring and after harvest at a rate of 50 pounds per acre. Average dry matter yields were very high in 1998 and few differences were found between performance of the varieties. If a yield difference between two varieties within a single column exceeds the LSD value at the bottom, you can assume that the higher yielding variety was truly better yielding.
