STATE CERTIFIED—STATE ORIGINATED 
High Points on Illinois 960 
• A very wide range of adaptability. 
• A top ranking Hybrid in production. 
• Extra High in Performance rating. 
• Yields of 123.9 bu. per acre are reported. 
The tests that have been made show Illinois 960 to be 
a very distinctive and outstanding variety. It has been 
grown in Illinois for three years. On account of seed 
scarcity most other states have had it for one year but it 
has shown up so well in such a wide range and under 
such varying conditions that it certainly is coming thru 
as a leader. We predict in another year or two when 
Illinois 960 is better known it will displace many varieties 
thruout a wide area on account of its adaptability. 
From north central Illinois thru central Iowa and east 
thru Indiana and Ohio and as far south as Missouri, it 
ranks high. No other Hybrid that we know of is adapted 
to so.wide a territory. We consider it good for southern 
Pennsylvania and West Virginia. 
In Iowa in 1937 it ranked first among all Hybrids in the 
experimental class in three tests and well toward the top 
in two of the other five districts in which it was tested. 
It gave a top yield of 108 49 bushels in 1937.

Indiana recommends it as a satisfactory Hybrid, espe¬ 
cially for the central part of the State. 
Illinois where the most extensive tests have been made 
for three years, Illinois 960 has made total yields of 123 9 
busheis per acre. In north central Illinois at Dwight, 
? e " ry ; ^ ra ssville and Cambridge, it was top in total yield 
io'/t S tS f° r *935 an d 1936. It was a high rating corn in 
1J37 with a yield of 120 bushels per acre at Cambridge, 
it also has been top in central and south central for a 
two-year average and top in southeastern Illinois in 1936. 
In soil adaptation tests Illinois 960 has been top in pro¬ 
duction on soils of both high, medium and low fertility 
It grows somewhat taller than most Hybrids and has a 
greater tendency to have two ears per stalk. We do not 
recommend it for planting north of Joliet, Illinois. Buy 
Illinois 960 Certified Hybrid for larger yields. 
A State Originated Hybrid 
Somewhat Later Type 
This Hybrid has an unusually superior per¬ 
formance in the southern half of Iowa and 
northern Missouri. Has produced yields 
showing it was adapted for the north central 
section and south central part of Illinois. 
This shows it would be adapted in a latitude 
for the southern part of Indiana and Ohio. 
We consider it adapted to all sections, hav¬ 
ing similar conditions and even farther 
south. 
It is not an experimental Hybrid, but one 
that for seven years with Iowa State yield 
contests has shown an average increase in 
yield over average open pollinated of 30.3% 
in southern Iowa and 28.91% in south cen¬ 
tral Iowa which reaches up to the middle of 
the state. Official reports show a yield of 
118.99 bushels per acre recorded for Iowa 13. 
This seven year superiority record of Iowa 
13 includes the drought years of 1934 and 
1936. Yields for 1937 range up to 97.30 
bushels per acre. 
In Illinois in 1935 Iowa 13 established a 
total yield in the north central section of 
109.7 bushels per acre in a test at one point 
in the section and 104.4 bushels per acre at 
another point. Again in 1936 it showed its 
superiority in taking the top ranking posi¬ 
tion in south central Illinois sharing honors 
with Hybrid Illinois 960. 
Iowa 13 is not a flinty, variety. It has a 
long strong root system. Our Iowa 13 is 
State Certified and has a very wide adapt¬ 
ability.

A State Originated Hybrid 
of Medium Maturity 
It was originated by the Iowa 
Experiment Station. Is widely 
grown in that state and in Illinois, 
Indiana, Ohio and on East. Earlier 
in maturity than Illinois 9G0. Has 
proven very popular in north cen¬ 
tral section of Ohio. 
In Illinois, the Iowa 939 Hybrid 
established yields in the north cen¬ 
tral part of the state of 107.3 
bushels total yield per acre at one 
station. It showed higher resist¬ 
ance against lodging in all tests. 
Has shown as high as 45% in¬ 
crease in yield over average open 
pollinated in central Iowa. 
Has nice shaped ears. Kernels 
have a slight reddish cast on the 
side. A softer corn than most Hy¬ 
brids. Fine feeding quality. Adapted 
for northern Illinois with the excep¬ 
tion of the top tier counties. Also 
same latitude in Indiana and north 
central Ohio. We have many testi¬ 
monials from customers who planted 
Iowa 939 last year. We have the 
genuine State Certified stock and we 
recommend it highly.
