KAFIR CORN 



101 



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 

 of 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 bo 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 phosphoric acid, and 

 104 pounds of potash. 



The same yield of maize will re- 

 move from an acre in eighty to 

 one hundred days only
