Numerous selections have been made to improve these varieties in 
height and earliness. and in the character of the head, and some 
progress has been made. Some of the best ones may stand com- 
parison with the selections of standard Blackhull kafir, but none is 
yet fitted to replace any of the commercial varieties of the United 
States. Complete data on these varieties are givenin Table XXVII, 
a study of which shows these kafirs to be very diverse in height and 
earliness. It is impossible, therefore, to consider them together, as 
for these and other reasons they do not comprise one variety but 
many. Itis desirable, however, to pick out some of the best of them 
and to compare them as individual varieties. The annual and average 
yields are given in Table XXVIII. 
No, 314, from Natal, is one of the best. It is fairly early, the aver- 
age duration of the vegetative, fruiting, and entire growing periods 
being 94, 37, and 131 days, respectively. The shortest growing 
period was 118 days, in 1914, and the longest was 138 days. In 
general, the stands have been fair to good, not as good as those of 
Blackhull kafir, but rather similar to those of Red kafir. Following 
the very thin stand in 1910, the tillering was enormous, the final 
result being two suckers to each main stalk. In no other year, how- 
ever, has the proportion been larger than about one sucker to two 
main stalks. 
The average acre yield of No. 314 is 13.1 bushels in the 8-year 
period. Two complete failures are recorded, in 1913 and 1916. The 
yield in 1915 was 46.7 bushels per acre. Had this variety been grown 
in plats in 1908, the most nearly normal in the whole nine years, its 
average yield probably would have been about 15 bushels per acre 
in the nine years. | 
No. 316, from Natal, is also worthy of consideration. Its growing 
period 1 is Anat the same as that of No. 314, the duration of the three
