The stand obtained from Red kKafir has been uniformly poorer 
than that obtained from Blackhull kafir. On the average, it has 
been about 35 per cent poorer. The best stand obtained was in 
1914, when each plant had only 7.4 inches of space. The poorest 
was in the very dry spring of 1910, when each plant had 42.1 inches 
of space. The average has been about 16.5 inches, or about 4 inches 
more than the average for Blackhull kafir. The difference in stalk 
space has not been very great, however, owing to the abundant tiller- 
Meee wm fed bal Th 1911 Red kafir was outtillered by the Black 
hull kafir, although the Blackhull already had the much thicker 
stand. In 1914 Blackhull again tillered more than the Red kafir, 
but in this year it had a thinner stand than the Red. In 1915, when 
the stand of Blackhull was about 9 per cent thinner than that of 
Red, its tillering was 6 per cent more. In 1910 and again in 1912, 
60 per cent or more of the Red kafir stalks produced were suckers. 
The average height of the Red kafir has been about 4.5 feet, which 
is about the same as that of Blackhull kafir. 
The yields obtained in the experiments with Red kafir are shown 
in Tables XXIV and XXV, and those of the leading selections are 
compared with the yields of other kafir varieties in Table XXX. A 
study of the datashows that the best Red kafir has made a 9-year
