Done the five-year period of 1927-1931, when less than 2 of 
1% of the Iowa corn acreage was planted to hybrid corn, an 
average of 11,279,000 acres were planted yearly to corn. The aver- 
age yearly production was 414 million bushels... for an average 
yield of 36.7 bushels per acre. It required about 135 million man 
hours per year to prepare the iand, haui manure, piant, cuitivaie and 
harvest the corn. 
But during the last five years, 1937-1941, when an average of 72 
per cent of the Iowa corn acreage was planted to hybrid corn, only 
an average of 9,830,000 acres were planted yearly to corn. Yet, the 
average yearly production was 482 million bushels .. . for an aver- 
age yield of 49 bushels per acre. And it required only about 118 
million man hours per year to prepare the land, haul manure, plant, 
cultivate and harvest the corn.

What a contrast—and how well this all fits into our war production 
program ...68 million bushels more corn per year on 1,449,000 acres 
less land, saving about *17 million man hours of work on corn. This 
makes 16.2 per cent more corn per year for livestock feeding, 10 per 
cent more land per year for other necessary war crops, and 13 per 
can now be converted to raising other vital crops, raising more live- 
stock, producing more dairy and poultry products . . . and even 
transferring some man hours to other branches of the war program. 
Pioneer has played a vital part in boosting Iowa corn yield to its 
present level and reducing the man hours involved in growing corn. 
*(17 million man hours are equivalent to 5,666 men working 10 
hours daily on every work day for one year.)
