The stand obtained from Red kafir has been uniformly poorer 

 than that obtained from BlackhuU 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 BlackhuU kafir. The difference in stalk 

 space has not been very great, however, owing to the abundant tiller- 

 ing in Red kafir. In 1911 Red kafir was outtiUered by the Black- 

 hull kafir, although the BlackhuU already had the much thicker 

 stand. In 1914 BlackhuU 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 BlackhuU 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 kafij" has been about 4.5 feet, which 

 is about the same as that of BlackhuU 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 data shows that the best Red kafir has made a 9-year
