North Dakota No. 305 emmer 



1,580 

 1,377 









The stand of the North Dakota No. 305 emmer in 1914 was very 

 thin; hence, the yield was abnormally low. For this reason the 

 comparison of average yields for the six years shown in Table XIX 

 is somewhat unfair to the emmer. White spring emmer grown on an 

 adjoining plat yielded 85 bushels to the acre. If this yield is substi- 

 tuted for that of the North Dakota No. 305 in the table, the average 

 yield is increased to 1,847 pounds. White spring spelt (C. I. No. 

 2968) was grown only in 1914, when it yielded 70.6 bushels to the 

 acre. Since the grains of emmer and spelt remain in the glumes 

 after thrashing, they are more comparable to oats and barley than to 

 wheat and rye. The yields here reported indicate that it is not ad- 

 visable to substitute spring emmer or spelt for oats or barley as a 

 feed grain in the Williston district. 



In 1912, 1913, and 1914 Black Voronezh proso (C. I. No. 16) was 

 grown in field plats. The yields of grain for the three years were 

 24, 22.1, and 29 bushels per acre, respectively. 



In 1914 Kursk millet was also tested in a field plat, producing a 

 yield of 38 bushels of seed per acre, 9 bushels more than the Black 

 Voronezh proso for the same year. 



In prosos the seeds ripen first at the tips of the heads. The crop 

 may be cut when most of the head is ripe and the tip begins to shatter. 

 The straw and leaves are still green at this stage, but the shocking 

 may be done so as to permit perfect curing without molding. A fair 

 quality of hay remains after the seed is thrashed out. 



Grain sorghums, especially early kaoliangs, have been tried at 

 Williston, but thus far have matured little grain. The grain sorghums 

 do not compare favorably in this district with the best varieties of 

 corn. 



SUMMARY. 



Cooperative experiments with cereals at the Williston substation 

 have been conducted for the seven years from 1908 to 1914, inclusive. 



The Williston substation is located in the extreme southern part of 

 Williams County, in northwestern North Dakota, at an altitude of 

 approximately 1,900 feet.
