The stands obtained for the Blackhull kafirs have been rather 
uniform and permit comparisons between years and between different 
selections in any one year. The desired spacing for kafirs was 12 
inches between plants in the row. As was the case with the milos, 
there appears to be no definite correlation between percentage of 
suckers and grain yield, the nearest to a correlation being between 
percentage of stalks headed and grain produced. The greatest 
degree of suckering was observed in 1917, when a second growth 
occurred. The average percentage of suckering for C. I. No. 204 
was 40.7 for the eight years. 
The average height of Blackhull kafir under Woodward conditions 
has been close to 4.5 feet, ranging from 3 to 5.5 feet for the varieties 
which have been grown for a period of years. Reed kafir (C. I. 
No. 628) in the two years it has been grown has been taller than 
either of the other two selections. 
From a study of grain yields it is seen that in normal years C. I. 
No. 71 is superior in yielding capacity to G. I. No. 204. The latter 
selection is an inferior strain or has deteriorated in yielding ability, 
as an average of 16.8 bushels per acre is unsatisfactory for Blackhull 
kafir under these conditions. 
SUNRISE KAFIR. 
Sunrise, or Early Blackhull, kafir (C. I. No. 472) originated at 
the Amarillo Cereal Field Station from a single head selected in the 
autumn of 1906. 5 This kafir has been grown at the Woodward 
Field Station since these experiments were begun in 1914. Because 
of its adaptation to Woodward conditions Sunrise kafir has been 
recommended by this station for the production of both grain and 
forage in that part of the sorghum belt where conditions are similar 
to those at Woodward, Okla., or where a medium early maturing 
kafir taller than the dwarf (Dawn) kafir is desired. Sunrise kafir 
has proved so satisfactory at this station that it has been used to 
represent the kafir group in the cultural experiments and has been 
distributed to farmers. A plat of this kafir is shown in Plate III, 
Figure 1. 
Sunrise kafir has been uniformly taller than any other selection 
of kafir grown in these experiments with the exception of a tall 
selection of an African kafir (C. I. No. 566). In earliness of maturing 
it has ranked second to White kafir (C. I. No. 370) and in some 
seasons has matured in as short a period as the White kafir. As 
grown at the Woodward station, Sunrise has shown better exsertion 
of head from the boot than any other kafir. The seed averages 
slightly smaller than that of ordinary Blackhull kafir. The com- 
plete experimental data recorded for Sunrise kafir are given in 
Table 9. 
The row space per plant has varied from 13.1 inches in 1914 to 
8.9 inches in 1916, the average for the eight years being one plant 
to each 11 inches of row space. Stalk space has varied from 10.4 
inches in 1914 to 3.9 inches in 1917, the 8-year average being 7 
inches. Sunrise kafir produces suckers freely, and its tendency in 
this regard is greater than that of any other kafir grown in these
