BREEDING MILLET AND SORGO FOR DROUGHT ADAPTATION. 
13 
sorghums produce much the largest tonnage of any of the annual 
forage crops tested. The average yield of four varieties of saccharine 
sorghums was 3.5 tons per acre, as compared with 1.3 tons for four 
varieties of foxtail millets, 1 ton for cowpeas, and 0.8 ton for field peas. 
From comparative yields at Akron, Colo., it appears that sorgo is a 
more profitable crop than millet from the standpoint of tonnage. 
In Table VII is given the average tonnage production of all varieties 
of millet in drilled plats and all sorgos in cultivated rows at Akron 
from 1910 to 1914, inclusive. The figures show that each year the 
relative yield was larger for sorgo, its average yield having been 40 
per cent higher than that of millet.

Some idea of the relative yield of the new strains of sorgo and 
millet described in this paper, as compared with other types of annual 
forage crops, can be had from the data presented in Table VIII.
