NORTHERN GREAT PLAINS FIELD STATION, 1913-1922 69 
Kubanka No. 8, a pure-line selection from Kubanka, leads all 
varieties in the seven-year average yield. Marquis ranks second, 
leading all the other varieties of common wheat. The differences 
in yield are not large enough to have much significance. Kota, 
an awned rust-resistant variety of spring common wheat, first 
included in the experiments in 1920, outyielded all other varieties 
in that year.” It is of good milling and baking qualities, is rather 
resistant to drought, but has weak straw. Haynes Bluestem gave 
the lowest vield “nearly every year and was discarded after 1921. 
The relatively low yield of Haynes Bluestem is typical of the results 
obtained by farmers in the vicinity of Mandan. 
EXPERIMENTS WITH OATS 
Yields of six varieties of oats grown from 1916 to 1922, inclusive, 
are shown in Table 27. Fair yields were obtained every year except 
1921, when all varieties except Sixty-Day failed to mature any grain. 
Sixty-Day is a short, early, yellow oat well adapted to North Dakota. 
Golden Rain is a yellow oat about 4 to 8 inches taller and a week or 
10 days later than Sixty-Day. It has produced the highest average 
yield during the seven-year period. Victory, a white oat of about 
the same height and time of maturity as Golden Rain, is second in 
average yield. This variety, because of its color, is preferred by 
many “farmers as a market grain. Both Golden Rain and Victory 
produced considerably more straw than Sixty-Day. Swedish Select 
is a white oat slightly shorter and earlier than Victory but not con- 
sistently as good a yielder. 
White Tartar (White Russian), a white side oat ripening a week 
or 10 days later than the midseason varieties, has produced the low- 
est yield in four out of seven years. Its average acre yield for the 
seven-year period has been about 9 bushels less than that of the two 
best varieties, Victory and Golden Rain.

EXPERIMENTS WITH BARLEY 
Yields of the six barley varieties grown from 1916 to 1922 are 
shown in Table 28. The two-rowed barleys all yield better than 
the six-rowed.
