SUPERIOR and STATE CERTIFIED 
U.S. 13 A PRIZE WINNER 
In 1939 and 1941 U. S. 13 was in the blue rib- 
bon class. In 1939 and 1941 it took practically 
all of the prizes at the International Livestock 
Exposition. It has an exceptionally fine pedi- 
sree of high producing inbred lines. .- It was de- 
veloped by the U. S. D. A. 
U. S..13 is a leader in the heart of the corn 
belt. Record yields prove beyond a.shadow of 
doubt that it is a front ranking Hybrid in any 
section where it is adapted. 
Illinois and Iowa tests show it high in pro- 
duction on different types of soils. It made front 
ranking position on soils of high, medium and 
low productivity. We know of no finer Hybrid 
on rich land. It is a large, deep grained, single 
eared variety. Has a deep golden color. Well 
dented Kernels, moderately rough. Has strong 
stalks and roots. Ears hang on well although 
it is not difficult to shuck. This is, really a 
show type corn. It is one of the softer Hy- 
brids. Popular with cattle feeders. 
State Originated 
CERTIFIED HYBRID 
It’s medium early. Was originated by the 
state. This Hybrid combination (Ax90) 
(WF9xHy) is known as Indiana 425 in In- 
diana. The inbred lines are all good ones. 
Illinois 751 is a little later than Wisconsin 
570 described on opposite page. In a test 
made in northern part of Illinois in 1936, 
1937 and 1938, for an average of three 
years, this was the highest yielding state 
originated Hybrid Corn. A state test made 
at Arlington Heights, Ill., in 1939, Illinois 
751 had a higher yield than other Hybrids. 
It beat other highly advertised Hybrids sold 
by Agents for $7.00 to $7.50 per bushel. In 
Indiana this same Hybrid, under the name 
Indiana 425, for the average of two years, 
1937-38, was the highest in yield of all 
Indiana Hybrids in all locations in a total 
of 15 experiments at 13 locations. Illinois 
751 produces a large sized well filled ear. 
We suggest this Hybrid for the northern 
one-third part of Illinois, except in counties 
near Lake Michigan. The northern half of 
Indiana and Ohio, and in similar latitudes. 
Try Illinois 751 this year and you will plant 
again next year.

U. S. 138 is adapted over a wide area. In 
Ohio, U. S. 13 was the highest yielding Hybrid 
in official.state tests in sections 9, 10, 11 and 
12, which are located in the southern half of 
that state. It yielded 101.9 bu. acre against 
80.7 for open pollinated. It also was top rank- 
ing in west central Illinois state test. It 
yielded 24 bushel per acre more than the aver- 
age open pollinated in the same test. 
In the southern half of Iowa in districts 7, 
8, 9, 10, 11 and 12, a chart taken from 1939 
Iowa corn yield test bulletin shows following 
average yield per acre: U. S. 13, 89.42 bu., 
U. S. 44, 89.19 bu., Illinois 960,.87.29 bu., Iowa 
Supercorn 119H, 87.21 bu., DeKalb 816, 85:87 
bu., Pioneer 313, 85.36 bu., Thompsons T81, 84.84 
bu., Lowe 523, 84.12 bu., DeKalb 827, ,83.78 bu. 
U. S..13 is; the Hybrid you want for. larger 
yields.

An Early Maturing 
State Originated Hybrid 
Sometimes a Hybrid will give a good per- 
formance for a year or two, but the best test 
of a variety is the results obtained over a 
period of years. That shows what it will do 
under varying conditions. 
Iowa 931 for eight years has yielded over 
16% more Corn than the average open pol- 
linated in the northern section of the Iowa 
State yield contest. It is also adapted for 
northern Illinois, extreme southern part of 
Wisconsin, northern part of Indiana. It is 
adapted as far south as 50 or 60 miles south 
of Chicago, in sections requiring an early 
maturing variety. 
Excellent Record 
It has a good.record in yield and strength 
of stalk. In a two-year record in northern 
Illinois, Iowa 931 showed very satisfactory 
performance of 103.1% and 102.5% with an 
acre yield up to 95.5 bushels per acre in 
1935. An early maturing corn that will, 
over a period of years show an average in- 
crease of 16.4% over open pollinated, is a 
good Hybrid to select. 
Buy Iowa 931 State Originated Hybrid. It 
has definitely proven itself superior.
