New land has been constantly developed and planted to potatoes. The 

 crop has been grown on an extensive rather than an intensive basis, and very 

 little attention has been given to the best cultural practices. Economic 

 conditions now demand, however, that growers follow the most improved 

 methods of potato growing, so that they can increase their yields per acre and 

 thus lessen the cost of production per bushel. The average yield of potatoes 

 per acre in Michigan in 1921 was 80 bushels. Many growers, however, in 

 various sections of the state secured yields of 200 bushels or more per acre 

 by practicing good methods of potato culture.
