CEREALS ON THE BELLE FOURCHE EXPERIMENT EARM. 
41 
Strains of Manchu Brown kaoliang produced the highest yields 
during all of the years from 1909 to 1916, inclusive. Complete fail- 
ures were recorded in 1912, 1915, and 1916, on account of early frosts 
which killed the plants before the grain was ripe. Drought and 
frost caused low yields in all other years except 1917, when a yield 
of 23.6 bushels of nearly mature kaoliang was obtained. The grain 
sorghums have yielded less than any of the other grains at Newell 
and are not adapted to the prevailing climatic conditions. 
COMPARISON OF GRAIN CROPS. 
A comparison of the yields in pounds per acre of all grains on 
the dry land at Newell are shown in Table XXIX. The yields 
shown are for the 5-year period from 1913 to 1917, inclusive, when 
nearly all of the small grains were being grown in plats. For the 
entire period of the cereal experiments at Newell the comparative 
yields of the crops would be somewhat different. The crops were 
not all grown under comparable conditions each year. However, 
the rye, winter emmer, and spelt were sown in the same series and 
on the same date as the winter wheat. The yields of spring wheat 
shown were obtained from replicated plats sown in the winter- wheat 
series each spring. The spring emmer was grown along with the 
barley varieties. The oats usually were sown in the same series 
with barley. The proso and kaoliang usually were sown on the 
same date and on adjoining land.
