1 Does not include 1919, because no data were available. The data for 1920 and 1921 were for F. C. I, 
No. 03418. 
In the sorgo group the black-seeded Ambers, Western Orange, and 
Black Dwarf matured seed more often than other varieties, but were 
inferior in yield and sometimes in quality of forage to Red Amber 
(fig. 6), Early Sumac, and other later maturing sorgos. Leoti Red, 
a sorgo tested only from 1920 to 1922, now^ appears more promising 
than either Red Amber or Early Sumac, but more data are needed to 
determine its value definitely. Such varieties as McLean, Colman, 
Collier, and Red X matured too late in most seasons and w T ere 
of secondary value to Kansas Orange and Sumac in the class of 
relatively late varieties. These late varieties have a limited value 
for fodder production in western Kansas, but in many years are 
unfit for silage because they do not have time to mature before they 
are harvested. 
Of the grain sorghums about half a dozen standard varieties 
produced average yields of 22 to 26 bushels per acre. Among these 
varieties a choice may be made based on local needs and conditions. 
Pink kafir (C. I. No. 432) gave best results from the standpoint of 
combining high yield and quality of forage with satisfactory grain 
yield. (Fig. 7.) Sunrise kafir produced equally good forage but 
was deficient in grain yield. Dawn kafir produced forage of fair 
quality, but of much less value than the yields would indicate.
