COMPARATIVE YIELDS OF THE KAFIR GEOUP. 



The annual and average acre yields of the leading races in each 

 variety of the kafir group are given in Table XXX. The average 

 yields are given for the 7-year, the 8-year, and the fuU 9-year periods. 

 The table contains yields of 17 lots, of which 5 are Blaokhull, 1 

 Sunrise, 1 Dawn (dwarf) , 1 White, 2 Red, and 7 new kafirs. Seven 

 of the lots have been grown throughout the 9-year period. 



In the seven years from 1910 to 1916, inclusive, the Dawn, the Sun- 

 rise, and C. I. No. 316, one of the new varieties, lead with average acre 

 yields between 17.5 and 17.9 bushels, that of the Dawn variety being 

 highest. A Red kafir (C. I. No. 356) stands next with an average 

 acre yield of 16.5 bushels, and Blackhull (C. I. No. 71) ranks fifth 

 with an average yield of 15.7 bushels per acre. In the 8-year period 

 the same three varieties lead, and Blackhull (C. I. No. 71) again 

 holds fifth place. Fourth place is taken by BlackhuU (C. I. No. 

 335), the Red (C. I. No. 356) having been grown only seven years. 



In the 9-year period. Dawn kafir still leads with an average acre 

 yield of 18.8 bushels. Sunrise has been grown only eight years and 

 Blackhull (C. I. No. 71) advances to second place with an average 

 yield of 17.3 bushels. Third and fourth places are occupied by 

 Blackhull selections, with average acre yields of 16.9 and 16.5 bushels,
