CEREAL EXPERIMENTS AT DICKINSON, N. DAK. 



37 



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. 



Tests with both winter and spring rye have been conducted 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 Rumker's green seeded (C. I. No. 174), 

 21.8 bushels; Von Rumker'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
