CEREAL EXPERIMENTS AT THE WILLISTON SUBSTATION. 30 
EXPERIMENTS WITH FLAX. 
The yields obtained from the varieties of flax that have been tested 
at Williston are shown in Table XVIII. In 1908 the flax was sown 
on ground that produced oats the previous year. In 1909, 1910, and 
1912 the flax varieties were tested on breaking. In 1911 they were 
on ground that was planted to corn the previous year, but that crop 
was destroyed by hail in August. In 1913 and 1914 the varieties 
were sown on fallow ground. In both these years the plats were 
so overgrown with Russian thistles that the yields were not considered 
comparable and hence are not reported. :

~ 1'Phese varieties were grown in 1913 and 1914, but the plats were so overgrown with Russian thistles 
that comparable yields could not be obtained. 
The average yields of the three lots of flax that have been grown 
for the four years (1909 to 1912) are practically the same, ranging 
from 15.5 to 16.2 bushels. In 1912 the race known as North Dakota 
Resistant No. 52, which was included in the tests for the first time 
that year, produced the highest yield. 
EXPERIMENTS WITH MINOR CEREALS. 
Experiments with the minor spring cereals at Williston have in- 
cluded three varieties of emmer, one of rye, one of spelt, one of proso, 
and one of millet. While emmer has given good yields for most of the 
six years tested, it has not proved to be a better crop than barley. 
Table XTX presents the annual and average yields for six years (1909 
to 1914) of one variety of emmer and one of rye with those of standard 
varieties of durum and common wheat and of oats and barley for 
comparison. ‘The average yields per acre are given in pounds as well 
as bushels, so that the comparison can be made more readily. 
Table XIX shows that oats produced more pounds of grain per 
acre than the best varieties of wheat, barley, emmer, and rye. The 
average yield of Siberian oats for the six years was 2,256 pounds to 
the acre; of Kubanka durum and Power fife wheat, 1,968 and 1,872 
pounds, respectively; of Manchuria barley (Williston No. 170), 2,088 
pounds; of emmer, 1,580 pounds; and of rye, 1,377 pounds.
