TaBLE 2.— Yields of Kubanka wheat selections and of the leading varieties of durum 
wheat grown in replicated plats at five experiment stations during one or more of the 
Jive years from 1918 to 1922, inclusive. 
[Five plats of each variety were grown at Moccasin and three plats of each at other stations except as noted, 
duplicate plats being marked with a star (*) and single plats with a dagger (t+).] ah 
Annual and average acre yields (bushels).

1 Not entirely comparable; grown in narrower plats. 
Of the selections and varieties grown in plats at Dickinson (figs. 
3 and 4) during the 5-year period, Nodak (Kubanka No. 98), averag- 
ing 17.8 bushels per acre, yielded the same as Monad and outyielded 
all other varieties, including the other Kubanka strains. In the 
2-year period Kubanka Nos. 99 and 117 yielded nearly as much as 
Nodak and Monad. 
In the two years at Fargo, N. Dak., Kubanka Nos. 99 and 94, 
averaging 33.2 bushels and 33 bushels, respectively, outyielded 
Nodak (Kubanka No. 98), the latter averaging 30.3 bushels per 
acre. In 1922 Nodak was also slightly outyielded by Kubanka No. 
74 at Mandan, N. Dak., and Moccasin, Mont., and by Kubanka No. 
117 at Edgeley, N. Dak. Yields for one or two years are not con- 
clusive. Results for five years at Dickinson, however, show that 
Nodak is well adapted to conditions there and probably to similar 
conditions elsewhere. Results for two years at Fargo indicate 
that Kubanka No. 99 may yield best in that locality. These results 
are further borne out by the data in Table 3, where the annual and 
average yields obtained from replicated nursery rows during six 
years at Dickinson and four years at Fargo are shown. Nodak ranks | 
high in yield, although not the highest, in the nursery at Dickinson, 
and Kubanka No. 99 stands high in the nursery at Fargo.
