 ANALYSIS OF YIELDS OF 370 EARS OF WISCONSIN. 



It has been amply demonstrated by American maize- 

 growers that the tendency to produce barren stalks can be 

 reduced by careful selection, and that the average yield of 

 grain per ear can be very greatly increased by breeding. The 

 figures in Table XXX (p. 147) show the yield per acre for 

 every ounce of average weight of grain per ear on a 75 per 

 cent stand of 6,534 plants per acre. 



These figures are somewhat startling. We are not

 obtained on any one South African farm without manure, 

 even with the best of seed and of good management ; but
