THE YOUNG FARMER 



proportion of cereals to other crops; or (c) 

 to a change in the ratio of the different 

 cereal crops. The following table, giving 

 the average yield of grain, reduced to 

 pounds per acre, shows not only how the 

 substitution of one cereal for another might 

 affect the total production of cereal grains, 

 but also suggests to the young farmer how 

 he may modify the total product of his 

 farm: 



Yield Lb. Lb. 



in bu. per bu. per acre 



Maize 24.2 56 1355 



Barley 23.7 48 1138 



Rye 15.0 56 840 



Oats 26.2 32 838 



Wheat 13.2 60 792 



Rice Paddy 746 



Buckwheat 14.0 48 672 



Yields will vary relatively in different 

 regions and with different types of soil, and 

 should be studied with reference to one's 

 conditions.

 creased about six and one-half times in 50 

 years, the hay crop five and one-half times, 

 while maize has increased four and one-half 

 times. Cotton, the only other great staple
