There Is a Big Difference in Hybrids 
The characteristics of a Hybrid corn variety depend entirely on the inbreds that are 
used to produce it. There are hundreds of inbreds and many hundreds of possible 
combinations. Some combinations produce exceptionally fine Hybrid Com. Some 
other combinations are fair and some are definitely inferior. There is a great differ¬ 
ence in the productiveness and quality of different Hybrids. Just because com is a 
Hybrid does not mean it is better than your own open pollinated corn. Some are 
much better, some are much poorer. 
Buy State or U. S. Govt. Originated Hybrids 
Private producers may sell Hybrids they have developed before their value is fully determined. Thus they 
can get their profits. State and U. S. Experiment stations develop many Hybrids but they only release to the gen¬ 
eral public those they consider definitely superior. These stations are not concerned with profit. All they are 
after is better corn for farmers to plant. When you plant State or U. S. originated Hybrids and buy only State 
Certified seed you know definitely that you are getting such varieties, properly prepared and that there will be 
no substitutions. 
State Certified Seed 
Our State Certified seed which sells at $JL.00 per bushel 
less than Multi-Perfected (see page 4) is for all practical 
purposes about equal to Multi-Perfected State Certified. 
However, this straight State Certified may come from dif¬ 
ferent growers than those producing the Multi-Perfected. 
Insofar as genuineness of variety, it is fully up to the 
strict standards set up for State Certification and equal 
or superior to any state certified seed. 
Grades, Varieties and Prices 
The grades of Hybrid seed corn that we' have are 
described on page 4. The prices are also given there. 
You will observe we have a limited supply of 1938 crop. 
That is available in all but U. S. 13 and Indiana 432. 
The small round grains are cheaper per bushel and a 
bushel will plant more acres. They will produce the 
same kind of com that the larger flat grains will pro¬ 
duce and apparently they yield just as well. 
Standard Multi-Perfected Hybrids 
This seed stock comes from growers who have a repu¬ 
tation as growers of quality Hybrid seed corn. The grow¬ 
ing and processing of Hybrid corn has a bearing on its 
yielding ability. The same variety produced by different 
growers may vary from 3 to 8 bushel per acre on the 
same variety. Multi-Perfected gives you what we con¬ 
sider Hybrids at their best. The following 10 points 
indicate the high character of this seed. 
1. The Variety is State or U. S. Government Originated. 
2. The seed stock for making the Hybrid is approved by the State. 
It is produced by expert Inbred growers. 
3. The isolation of the seed field has State inspection. 
4. The vitally important work of detasseling is checked and 
okayed by the State. State specifications are surpassed. 
5. The variety is proven superior in yield and stalk strength. 
6. It i§ dried to 14% moisture. Freezing cannot injure germination. 
7. The seed germinates 90% strong or better. Often 98%. 
8. The seed is State Certified. 
9. The seed is carefully graded and processed. 
10. The crop is properly and expertly grown. 
Highest Producer, 6 year average—Northern 
Iowa 
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. 
In State yield contests in the northern part of 
Iowa this Hybrid has proven to be 10.4 percent bet¬ 
ter than average ordinary com over a period of 8 
years. The bushel increase in yield has been as high 
as 17.62 bu. per acre over ordinary. The agre yiem 
has been recorded up to 95.5 bushel per acre. .n 
percentages it has outyielded ordinary corn by as 
much as 24.4 percent. 
Iowa 931 is not a new and untried 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 conditions. 
This variety is not as flinty as many of the earlier 
maturing varieties. The kernels are medium rough 
and have 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 than extremely hard 
corn. Flinty corn may also be discounted on 
the market. When you get a variety that 
combines heavy yields and good eating quality 
you really have a money maker.

Heaviest Producer, 6 year average—Southern 
Iowa 
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 conditions. 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 pollinated 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, 1939 
being its 9th year in state yield contests. The ex¬ 
amination of its records when judged over a term 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 Illinois. In 
1936 it shared top honors in the south central portion 
with Hlinois 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 im¬ 
portant from a feeding standpoint. 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 appreciate this.
