this variety is early in maturing and that the yield of grain is high. 
Pink kafir has a white glume mixed with red. while the seed is white 
with red spots of varying size. 
COMPARATIVE YIELDS OF THE KAFIR GROUP. 
The annual and average acre yields of the selections of the kafir 
group grown in these experiments are given in Table 10. Six vari- 
eties of kafir have been grown for the full S-year period, one strain 
each of Blackhull, Sunrise, Dawn, and Red, and two of White kafir. 
For the 8-year period, Sunrise kafir leads in grain yield with an 
average of 26.3 bushels per acre, Dawn ranks second with 23.8 bushels 
per acre, and Red kafir is third with an average yield of 20.8 bushels. 
Of the varieties and selections not grown for the entire 8-year 
period, several show high yielding power. Blackhull kafir (C. I. No. 
71) in the five years it has been grown has yielded slightly less than 
Dawn during the same period and has averaged 3 bushels per acre 
more than Red kafir. Reed kafir (C. I. No. 628) has been grown for 
but two years, during which it has averaged more grain than any 
other kafir in the experiments. The tall type of White African kafir 
(C. I. No. 566) has made a very good showing during the years since 
it was separated from the dwarf type. 
The yields obtained show that Sunrise and Dawn kafirs are well 
adapted for grain production under conditions at the Woodward 
Field Station.
