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 ae (C..1. 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 leayes 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 oe 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.
