Open Field Pollinated Corn 
Sunfield’s open field pollinated corn is the kind of seed corn 
that has been generally planted. That is, it is not Hybrid. 
The varieties listed below are described for their general per¬ 
formance and maturity. The seed is selected stock, well dried, 
carefully graded and good germination. It is to my interest 
to see that you get good seed of heavy producing strains and 
it is to your interest to plant such seed. The cost of planting 
an acre of such seed is small and an increase in yield if only 
a bushel an acre will generally more than pay the entire seed 
cost. See my seed corn guarantee on page 18.
