SORGHUM EXPERIMENTS ON THE GREAT PLAINS. 
Table 13. — -Forage yields of sorghum varieties and of corn grown at eight station-, 
in the northern Great Plains area, for one or more seasons in the 9-year period 
from 1914 to 1922, inclusive. 
[The official titles for certain of these field stations are as follows: At Newell, S. Dak., the Belle Fourch 
Field Station; at Mandan, N. Dak., the Northern Great Plains Field Station; at Moccasin, Mont., the 
Judith Basin Field Station. The fodder was field cured, except that all yields at Havre, Mont., and those 
for 1922 at Redfield, S. Dak., are on an air-dry basis. The yields given in the "Average of corn" columr. 
are the average yields of corn for the years in which the sorghum variety opposite was grown.]

SUMMARY OF VARIETAL EXPERIMENTS. 
The results obtained at experiment stations and the experience of 
farmers indicate that the sorgos (sweet sorghums) are superior to 
the grain sorghums whenever forage alone is desired. In hay, fod- 
der, and silage yields, well-adapted varieties of sorgo have excelled 
the best varieties of grain sorghum in every part of the Great Plain-
