CEREAL EXPERIMENTS AT DICKINSON, N. DAK. 3% 
EMMER. 
Three varieties of spring emmer were grown during the 3-year 
period 1907 to 1909. The highest average acre yield was 50.1 bushels 
for the Yaroslav (C. I. No. 1526). This variety has been continued, 
but in 1910 and 1912 the crop was destroyed by hail. It has produced 
an average acre yield of 46.2 bushels for five years (1907 to 1909, 1911, 
and 1913). The yield of emmer was computed at 40 pounds per 
bushel. The annual and average yields of grain in pounds per acre, 
with that of the leading varieties of oats, barley, and wheat, are 
given in Table XIX.

Table XIX shows that the Yaroslav emmer gave a higher average 
acre yield of grain for the five years than Early Mountain oats, 
Hanna barley, or Kubanka wheat. Upon actual food content the 
yield of wheat is considerably more than the figures indicate, as a 
certain percentage of the emmer, oats, and barley grain is composed 
of hull. 
RYE. 
Tests with both winter and spring rye have been condueted at 
Dickinson for several years. With the exception of one year (1913) 
the results are of little or no value, the crop having been destroyed 
or badly damaged by hail. In 1913 three varieties of winter rye 
and one variety of spring rye were grown. They were sown on land 
_ which had been cropped to corn in 1912. The following acre yields 
of grain were obtained: Winter rye, North Dakota No. 959 (C. I. 
No. 175), 31.1 bushels; Von Riimker’s green seeded (C. I. No. 174), 
21.8 bushels; Von Riimker’s yellow seeded (C. I. No. 173), 19.4 bush- 
els; and spring rye (C. I. No. 169), 21.3 bushels. The common win- 
ter rye yielded 46 per cent more than the common spring rye. 
The two varieties from Dr. von Riimker were obtained from Ger- 
many in 1911 by Supt. L. R. Waldron, of the Dickinson substa- 
tion. They were originated by Dr. K. von Riimker, of Breslau, from a 
selection from the variety Petkus made in 1899. Reselections were 
made toward the yellow and green types for the 10 years following. 
About 35 per cent of each of these varieties winterkilled during the
