Uniform Bromegrass Trial
The hay yields for the 1960 season of the 14 strains of smooth bromegrass included in the uniform bromegrass trial are give in Table 5. The 6-year average yields for all strains in the trial are given in Table 6. These plots were seeded in 1953, and some of the plots show considerable deterioration of stand, although invasion of other grass and weeds has been very light so far. The plots of Canadian commercial, Manchar, Martin, Kuhl, and Mandan 404, were noticeably less vigorous and thinner in the 1960 season than in previous seasons.

|Composition of Yield|
|Variety||Grass||Other Grass||Weeds||Total Plot Production - Lbs./Acre|
The average production of seeded grass for all brome varieties was 1054 pounds per acre this year. Achenbach, a southern type, was top producer at 1247 pounds per acre. Oklahoma synthetic at 1131, Lincoln at 1103, and Fischer at 1093 were next in order. Martin, at 971 pounds per acre, was the lowest producer of this group. Martin is an old-field strain from Minnesota and is considered to have southern-type characteristics. In general the southern bromes continued to show somewhat greater productivity than the northern types. However, differences between the types were not pronounced this year and Elsberry (Missouri) and Martin (Minn.) joined the northern types at the bottom of the list.
The data of Table 6 shows that on the average Lincoln brome has had a slight over-all advantage in productivity, followed closely by Fischer, Achenbach, and Oklahoma synthetic. Of the northern type bromes Manchar, Mandan 404, and Homesteader all have about the same average yield, with the range being only from 1124 pounds per acre for Homesteader to 1130 pounds per acre for Manchar. Canadian commercial, with a 6-year average yield of 1030 pounds per acre, appears to be slightly less productive than the other northern strains.
