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 an imposing record of production. 
We give it our recommendation for all sec¬ 
tions having conditions similar to north 
central Illinois, south central Iowa and from 
there way down south into Mo., Okla., Ky.

Description of 960 
It is a pure yellow corn with a very good 
depth of gram. 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. 
1 he grains and rows are closely spaced mak¬ 
ing a good solid ear. Kernels are not flinty 
The stalk growth is a little taller than the aver¬ 
age hybrid. 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 
Some Yield Reports 
The following information is gathered from 
state yield records and letters and bulletins 
received from State Experiment Stations. In 
Illinois 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, W T ayne, 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 9014 bu. 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-

HANS 
Where we suggest planting Illinois 960 
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. 
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. It is a very popular Hybrid with Indiana 
farmers and is grown extensively in Penna. Also in New York. It is widely adapted. 
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 
mmmmmmmmmmm _____ the ears good protection yet when ripe is a very 
) eas y corn to husk. Nearly every farmer that we W i 
7 x3r know of who have grown Iowa 939 speaks very mi 
highly of it and want to continue growing it. 
We believe this variety to be adapted to the 
shaded area shown on the map below. mA
