shown on the left . . . a four-year trial of top 
yielding performance . .. proof of superior 
quality and superior profit-making ability.

It’s FIRST IN YIELD among all hybrids 
with a four-year average in the North Central 
Section . . . FIRST IN YIELD and FIRST 
IN LODGING RESISTANCE among all hy- 
brids with a four-year average in the Northern 
Section. 
These records were made under growing con- 
ditions similar to those that exist on your farm. 
It’s no wonder thousands of North Central

planting Pioneer 322 each year—and benefiting 
from its long-time, high yielding dependability.
