KAFIR CORN 
911 pounds, or 19 per cent. On 
the dry matter basis, therefore, 
the only variety that at all com- 
pared with maize was the Ever- 
green broom-corn, which is very 
inferior in palatability and diges- 
tibility. The kafir corns are not 
comparable with corn on the basis 
ef yield of nutrients, and are not 
to be recommended except as sub- 
stitutes for corn in climates too 
dry for the latter. 
One point should not be lost 
sight of with all these quick-grow-. 
ing summer crops,—they are 
relatively exhaustive of the avail-. 
able plant-food in the surface 
soil. For example, a crop of eight 
tons of Barnyard millet, which 
fairly represents this group of 
forage crops, will remove from 
an acre in fifty to seventy-five 
days in round numbers 
50 pounds of nitrogen, 
26 pounds of phosphorie acid, and 
104 pounds of potash. 
The same yield of maize will re- 
move from an acre in eighty to. 
one hundred days only
