CEREAL EXPERIMENTS AT THE WILLISTON SUBSTATION. 23 
winter wheats. They have bearded heads and white, glabrous glumes, 
except that North Dakota No. 1997 has become somewhat mixed and 
contains some plants with red glumes. 
The Beloglina produced an average yield of 15.7 bushels for the six 
years, and North Dakota No. 1997 yielded 15.3 bushels per acre. 
The average yield is reduced because of the total killing of the 1912 
crop. As previously stated, the plats were on bare ground that year. 
The Beloglina was sown also in another location between corn rows 
and the stalks left standing all winter. The spring survival of this 
plat was good and a yield of 35.1 bushels per acre was harvested. 
Substituting this yield in the year 1912, when there was no yield from 
the plat sown on bare ground, would raise the average yield for 
Beloglina from 15.7 to 21.6 bushels per acre for the six years. 
Buffum No. 17 (C. I. No. 3330), introduced into the tests in 1913, 
gave a higher spring survival in 1913 and 1914 and a higher yield of 
erain than either Beloglna or North Dakota No. 1997. The heads 
of Buffum No. 17 are beardless and the glumes are glabrous. In 
appearance it resembles Ghirka Winter wheat (C. I. No. 1438). The 
other varieties have bearded smooth-chaffed heads. 
With these results with winter wheat at Williston it would seem 
that a good spring survival can not be had unless the plants have 
some such protection as cornstalks or grain stubble. To seed on corn 
ground and leave the stalks standing is too expensive where the corn 
fodder is valued as highly as it is in the Williston district. 
In date-of-seeding trials of winter wheat at Williston it has been 
found that seeding about the middle of August gives better results 
than later seeding. If the stubble ground of some spring grain is 
used for the winter wheat, it is necessary to seed almost as soon as 
the grain crop can be removed. However, if the autumn is about 
normal in. rainfall, there is likely to be insufficient moisture in the 
stubble land to germinate the seed. ; 
NURSERY TESTS OF WINTER WHEAT. 
Winter wheat has been tested in the nursery at Williston since 1911. 
Selections have been made from the varieties that have shown the 
hardiest qualities. Selections also were obtained from hardy varieties 
at the substations at Moccasin, Mont., and Newell, S. Dak. 
Different methods were used in preparing the ground for seeding. 
Some sowings were made on bare ground, some in standing corn, 
some in grain stubble, and some by covering the rows lightly with 
straw. Whenever the rows were protected in any way by a covering 
of straw or snow, the winterkilling was very slight or there was none 
at all. Whenever the rows remained without covering, most or all 
of the plants were killed.
