Some of the other promising varieties are Nos. 303, grown during 
eight years, No. 321, grown in seven years, and No. 432, grown 
during five years. Comparative results will be found in Table 
XXVIII. The 8-year average acre yield of No. 303 is 11.5 bushels. 
The 7-year average acre yields of Nos. 303 and 321 are 13.1 and 13.5 ¢ 
bushels, respectively. The 5-year average acre yields of the three 
numbers are 12.4, 12.8, and 16.7 bushels, respectively.

GUINEA KAFIR. 
The variety here called Guinea kafir is an old variety in this 
country which is not now grown commercially, so far as known. It 
was widely advertised and tested 50 years or so ago under various 
names. Among them were such as ‘Rural Branchmg Sorghum,” 
“White Millo Maize,” etc. It was then grown to some extent in the 
Southern States, being too late to mature anywhere else. Although 
carefully tested both in the nursery and in field plats at the Amarillo 
Cereal Field Station, it has shown no adaptation for the dry lands. 
It is too tall, too late in maturing, and too poor a yielder of grain 
to be of commercial value, even under conditions more favorable than 
those of the Texas Panhandle. Some popular interest still attaches 
to it, and for this reason it has been carried in the experiments during 
the entire nine years. The results obtained are shown in Table 
X XIX and comparatively in Table XXX and prove how poor it is 
under such conditions. Even in 1915 it was unable to make a better 
yield than 35 bushels per acre.
