BULLETIN 1260. U. S. DEPARTMENT OF AGRICULTURE. 
by these tests was 1 inch above normal, and if it had been properlv 
distributed it would have been sufficient every year except 1917 to 
produce a good crop. In fact, sorghum has proved to be the most 
dependable crop at Dalhart. both forage and grain. The small yields 
in 1918 resulted from the small amount of rain received during the 
last four months of 1917 as well as the low rainfall in June. July" and 
August. 1918. The last three years. 1919 to 1921. were exceptionally 
favorable during the growing seasons and the yields were above 
the average. 
Dalhart is located on the high plains of northwestern Texas, having 
an altitude of 4.000 feet. This altitude shortens the season some- 
what and interferes with seed production in some of the late varieties. 
such as Sumac and Honey. 
The actual and relative yields of grain and forage for each year 
from 1916 to 1921 are given in Table 10. Sumac is used as the check 
variety for the sorgos: and Sunrise kafir was chosen as the check 
for the grain sorghums, because it has seemed better adapted to 
Dalhart conditions than Dawn kafir.
