Farmers Nationwide Turn to Hybrid Corn 
Th« large yields and stronger stalks of the better varieties of Hybrid 
corn have proven them so decidedly superior to the average open polli- 
nated corn that farmers are interested as never before. After you have 
^ grown a real good Hybrid we do not believe you will ever want to go 
^ back to the old type. 
But there is a tremendous difference between one variety of Hybrid and another. The 
difference is much greater than that between most kinds of ordinary corn. Some Hybrids 
are too hard and flinty. Some stick the ears out of the husks too early and are subject to 
more damage. There are other differences and defects. Therefore, if you have observed 
any defects in some Hybrids do not condemn all Hybrids but rather the particular varie¬ 
ties in which you may have observed such things. 
Why We Seli State Originated Hybrids 
The kind of Hy- 
Hybrids are made by crossing’ inbred lines of corn. It takes 6 to 7 years to make these inbreds, 
brid you get depends on what kind of inbreds ai'e crossed. Many crosses produce corn that is inferior to ordinary 
corn. Only a few are truly superior. Those that are superior have much greater value than ordinary com. 
It costs money to develop inbreds and make crosses. It takes a long time. State experiment stations make these 
developments. Some work is also done by private firms for an ultimate profit. The State Experiment Stations how¬ 
ever,- are not concerned about private profits. All they are after is a corn that is really outstanding in its performance. 
They do not release Hybrids to the public until they feel sure they are proven worthy. They are therefore safe varie¬ 
ties to select for their adapted location. We sell only State Originated Hybrids. 
Why We Sell Only State Certified Hybrids 
To be sure of a good Hybrid of any variety you must have the right seed, the field must be properly isolated and 
the detasseling of the seeds rows must be thorough. 
State Certification established that the planting stock, the isolation and the detasseling has all been approved by 
State authorities. It further established that the variety itself has been proven superior to ordinary com in yield and 
strength of stalk. Further, all “Certified” seed must be dried to 14:% or less moisture and show a strong germination 
of 90 % or better. Therefore the Blue State Tag of Certification which is attached to every full bushel bag of our Hy¬ 
brid Corn gives you the information that the seed has complied with all the 0 points necessary for State Certification. 
Why We Sell the Varieties Listed 
We have selected the four state originated Hybrids described on these pages because we consider them to be desirable 
hybrids from the standpoint of yield, and of a quality making them desirable to feed. In oiher words Hybrids that we 
believe our customers will really like and want again from year to year. You should find it to your interest and profit 
to plant such com. We are ■’nriciner this “State Certified” seed at prices that save you $1.00 to $2.00 per bushel. 
This is our earliest maturing Hybrid. It was de¬ 
veloped by the Iowa Experiment Station for condi¬ 
tions in northern Iowa. We, therefore, suggest plant¬ 
ing it where similar seasonal conditions prevail. The 
map below gives our ideas on the adaptabibty of 
Iowa 931. 
In State yield contests in the northern pait of 
Iowa this Hybrid has proven to be 16.4 percent bet¬ 
ter than average ordinary corn over a period of 8 
years. The bushel increase in yield has been as high 
as 17.62 bu. per acre over ordinaiT. The acre yield 
has been recorded up to 95.5 bushel per acre. In 
percentages it has outyielded ordinary corn by as 
much as 24.4 percent. 
Iowa 931 is not a new and tmtried variety. It 
has now been in production for nine years and is 
truly a time tested Hybrid. In considering tests one 
should remember that in some favorable year a Hy¬ 
brid of later maturity might show a little better 
record, but the same variety the next year might be 
way down because of improper maturity. The long 
proven record-on 931 proves its adaptability year in 
and year out to Northern Iowa and similar climatic 
conditions. Map gives our idea of its northern limits. 
This variety is not as flinty as many of the earlier 
maturing varieties. The kernels are medium rough 
and have a distinctive reddish cast on the side sim¬ 
ilar to the Iowa 939. It is important to bear in 
mind that a corn which is less flinty will be 
eaten much more readily thr i extremely hard 
corn. Flinty corn may also be discormted on 
the market. When you get a variety thet 
combines heavy yields and good eating qualiiy 
you really have a money maker. 
This variety is especially adapted to climatic con¬ 
ditions such as prevail in the southern half of Iowa 
and northern Missouri, It should do well in all sec¬ 
tions having similar cbnditions. Iowa 13 has shown 
that it is an exceptional resister against drought con¬ 
ditions. Over a period of seven years it has in the 
southern Iowa corn yield contest an advantage of 30.3 
percent in yield and in the South Central section 28.9 
percent superiority. That is a remarkable rating to 
extend over a seven year period. It’s outstanding per¬ 
formance was in the drought year of 1936 'when it 
outyielded other Hybrids by 26.9 percent and the 
average open polhnated 79%. It took the banner 
trophy in the southern Iowa district. Iowa 13 has 
recorded yields of 118.99 bushels per acre. 
Like 931, Iowa 13 is a time tested Hybrid, 1938 
being its 8th year in state yield contests. The ex¬ 
amination of its records when judged over a tenn of 
years shows its high rating. Not only is its record 
good in Iowa. It has shown well in other states. In 
1935 it yielded 109.7 in North Central Hlinois. In 
1936 it shared top honors in the south central portion 
with Illinois 960, In 1937 it made a yield of 105.4 
bushels at Maryville, Missouri, which is in the north¬ 
ern part of that state. 
Iowa 13 shows high yields, with adaptability and 
also is not so hard and flinty. That is important from 
a feeding standpoint. Big yields are discounted 
in value if cattle and hogs will not eat it. 
We have never had a complaint from our 
customers on excess hardness and consider 
that a most desirable factor. Any who have 
grown the very hardy flinty kinds will ap- 
\ fiAY SAFE ^ Bit/ 
predate this most. We consider this variety 
especially good for extra drought resistance.
