7 BUSHELS PER ACRE 






Pioneer 324 produced the highest yield among adapted varieties in the 1940 yield test conducted 
by the North Iowa Agricultural Experiment Association, at Kanawha, Iowa, in Hancock County. Forty- 
nine varieties were tested. Pioneer 324 yielded 78.4 bushels per acre—7 bushels per acre more than 
the average commercial hybrid—and held the same moisture content as the average commercial hybrid. 
AVERAGED 3.8 BUSHELS PER ACRE MORE IN NORTHERN SECTION 
In the Northern Section of the Official 1940 Iowa Corn Yield Test, 324 outyielded the average 
hybrid 3.8 bushels per acre, showed only 1.4 per cent more moisture. In the North Central Section, 
it outyielded the average hybrid and contained less moisture.
