CEREALS ON THE BELLE FOURCHE EXPERIMENT FARM. 



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.
