Intermediate-Pubescent Wheatgrass Plots
The 1960 hay yields from the intermediate-pubescent plots seeded in 1954 are given in
Table 1. Table 2 gives the average yields of the varieties in this trial over the 6-year
period, 1955-1960. The 1960 yields given in Table 1 show the composition of the yields in
terms of seeded grass, other grass, and weeds. It is apparent that there has been
considerable deterioration in stand with nearly all the varieties. This is shown by the
relatively high proportions of "other grass" in the stands, especially in the
stands of North Dakota pubescent and A-14296. Most of this deterioration of stand has
taken place since 1958. The "other grass" in the plots is invading crested
wheatgrass. Weeds were not important in the 1960 season.

The data of Table 1 show that in the relatively favorable 1960 season M-2-10820, Ree Wheatgrass, and Pubescent Wheatgrass produced the best yields. However, most of the plot yields were fairly close together, with only N. Dak. Pubescent and A-12496 distinctly lower than the other varieties in production of seeded grass. The average plot yield of 1462 pounds per acre for all varieties was about the same as last year's average production of 1439 pounds per acre.
On the basis of the average plot yields for the period of the trial (Table 2), the
intermediate wheatgrass strains seem to be slightly more productive than the pubescent
wheatgrass strains. All varieties have averaged over 3/4 ton of hay for the 6-year period,
with Ree wheatgrass having an average production of over one ton per acre for the period.
