Numerous selections have been made to improve these varieties in 

 height and earhness 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 given in Table XXVII, 

 a study of which shows these kafirs to be very diverse in height and 

 earhness. It is impossible, therefore, to consider them together, as 

 for these and other reasons they do not comprise one variety but 

 many. It is 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 

 BlackhuU 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 is about the same as that of No. 314, the duration of the three
