Description of Iowa 939 
It is a variety of medium early maturity. It forms more uniform ears than many Hybrids, 
looking more like ordinary corn yet outyielding it materially. The kernels are 
of a medium rough type. Kernels are fairly broad and of good depth. The sides 
have a distinctive reddish tinge. They are not as hard and flinty as those 
of many hybrids and are readily eaten by cattle and hogs. 
It has strong roots and stalks. The husks give 
the ears good protection yet when ripe is a very 
/ easy corn to husk. Nearly every farmer that we 
v.'*"* I (know of who have grown Iowa 939 speaks very 
jj - highly of it and wa’nt to continue growing it. 
ry We believe this variety to be adapted to the

An Extra Fine 
High Quality Hybrid 
The development of Hybrid varieties 
seems to have been more of the earlier 
types. Kinds suitable to Central Iowa 
conditions and north. While Iowa 13 is 
good for the south this Illinois 960 shows 
a number of improvements. A wider adapta¬ 
bility and a superior quality. Here is a hy¬ 
brid with such an imposing record of pro¬ 
duction that we give it our most enthusiastic 
recommendation for all sections having con¬ 
ditions similar to north central Illinois, south 
central Iowa and from there way down south 
into Kentucky. 
Some Yield Reports 
ers. At Ridgely, Maryland, it 
yielded 72.4 bu. per acre and lacKed 
only a fraction of a bushel in being tops 
in yield. 
Ohio reports they consider Illinois 960 
a good Hybrid for the southern portion 
of the state, and they are entering it in 
the certification list. It was one of the 
3 best with an average yield of 4 tests 
in the southern section of 78.6 bu. per acre. 
The Indiana experiment station reports it 
did very well in several tests in the Central 
part of the state and that it should be a sat¬ 
isfactory variety. The fact that it also was 
one of the best in Kentucky would indicate 
its adaptability to southern Indiana also. 
The following information is gathered from 
state yield records and letters and bulletins 
received from State Experiment Stations. In 
nil^is over three year average it was heav¬ 
iest producing corn in north central, central 
and south central sections of the state, and 
for a two year average the heaviest produc¬ 
ing in the southeastern section. In another 
Illinois soil adaptability test it was the heav¬ 
iest yielder on soils of high, medium and low 
fertility. Remember that some hybrids re¬ 
quire rich soil while 960 has given top per¬ 
formance on a wide variation in soil. 
In southern Iowa, Illinois 960 was tested 
in Mills, Wayne, Henry and Johnson coun¬ 
ties. The average of these tests showed 960 
the heaviest producer of all Hybrids and out- 
yielding ordinary corn by about 19 bushel 
per acre. The average yield of 960 in the 
four tests was 90bu. per acre with a top 
production of 108.49 bu. 
In northern Missouri in test with 65 other 
Hybrids, Illinois 960 was the top 
of all commercial varieties with a 
yield of 112.2 bushel per acre. 
Other State Reports on 960 
It was top in eastern Nebraska. 
In Kentucky it classifies as a me¬ 
dium early variety and on the Ex¬ 
periment Station farm at Lexing¬ 
ton was among the highest yield- 
\4Tiere we suggest planting Illinois 960 
Description of 960 
It is a pure yellow corn with a very good 
depth of grain. The kernels are not as broad 
and shallow as some but narrower and longer. 
It is more like a smooth type of Reid’s Dent. 
The grains and rows are closely spaced mak¬ 
ing a good solid ear. The kernels are not ex¬ 
cessively hard and flinty. 
The stalk growth is a little taller than the aver- 
ag-e hybrid. In our seed fields and in fields of 
Commercial 960 that we have inspected the stalks 
have stood up well. It is a very strong rooted 
corn. The ears of 960 remain better protected by 
the husks than many Hybrids. It does not have 
the tendency to protrude its ears while the grain 
is still soft. 
On thin stands the Illinois 960 has a strong tend¬ 
ency to form two nice sized ears per stalk. There- 
fpre even with thin stands it yields well and on 
different soil types maintains ex¬ 
cellent performance. 
By actual tests it has proven 
itself an outstanding Hybrid and 
we urge its planting because we 
believe it to be one of the best 
yielding and 
most profitable 
and satisfactory 
Hybrids yet de- 
veloped. We 
consider it suit¬ 
able to approx 
imate territory 
shown in the

on the map

STATE 
A development of the Iowa Experiment Station that has spread from Central Nebraska to the 
eastern coast and proven a very remarkable Hybrid. It is earlier in maturity than 960 going 
North up to the two northern tiers of counties in Iowa and going south into northern Missouri 
with very enthusiastic reports from farmers in that section. This indicates its wide adaptability 
in sections having similar conditions. 
Iowa 939 has made some wonderful yield records in state tests. In Iowa it has averaged 20% 
increase in yield over o.p. corn going as high as 40% increase. In one test it outyielded all other 
Hybrids. In Nebraska it was the top yielding Hybrid over a 5 year average outyielding ordinary 
corn by 23% or an increase of 10 bushel per acre. It is a “time-tested” variety. 
Illinois gives 939 recorded yields of 107.3 and 103.8 bushel per acre. In an Ohio report it topped 
all of the early Hybrids with a yield of 98.1 bushel per acre. This variety has been widely grown 
in West Virginia tests and it has shown up very well indeed and is suggested for elevations up to 
2000 feet or where a medium early variety is desired. 
There are many other sections from which official reports are not available. Considering what 
Iowa 939 has done at such widely separated points indicates ah adaptability to a wide territory.
