Another exceptionally good hybrid, one which is grown by nearly every large producer of hybrid 
corn under some number or other. A very nice looking large ear, smooth, good color, deep even grain. 
One of our best varieties of corn for feed. Does not grow tall and stands up the best of any hybrid 
Usually will produce one large ear to a stalk. A topnotcher in three or four 
_we have to offer. 
of the corn belt states and one which every farmer should grow some of. Yields exceptionally well 
in central Iowa. ure 
CERTIFIED IOWA 939 
For a good many years we have sold thousands of bushels of hybrid seed corn in 
Iowa and Nebraska. In certain sections we have had such a demand for Iowa 939 that 
we are producing it this year. The growing of this corn has been supervised by the 
Illinois Crop Improvement Association and will be certified by the Iowa Agricultural 
certifying agency. 
Iowa 939 is a number which has been produced a good many years. While for 
most sections of Illinois we have hybrids which are much better than Iowa 939, there 
are some sections in Northern Iowa and Nebraska to which Iowa 939 seems naturally 
adapted. This is not a tall growing corn—only medium height. Rather ruff type. Light 
yellow colored ear 8 to 11 inches long. A very desirable hybrid for feeding purposes. 
For price, see inside back cover. 

The above shows one of our single cross fields which is another big expense in producing hybrid 
corn. We take two inbreds and make single cross in isolated fields which must be at least 40 rods 
from any other corn, and it certainly is hard to get fields which are isolated 40 rods in every direc- 
tion. With the best planning one field in 160 acres is the best we can do. This oftentimes only 
yields from 3 to 15 bushels per acre and this is what we have to plant then to make the four-way 
cross which produces commercial hybrid corn. This all has to be detasseled just the same as the four- 
way cross.
