HENNING HYBRID 
SEED CORN 
Henning Hybrids are certified and of guaran¬ 
teed quality. They are all pedigreed. Buying a 
Corn hybrid that does not list the pedigree is 
just like using a scrub bull. Henning Bros, are 
reliable, and all their hybrids are graded with 
the Buckeye Hybrids, Inc., grader which insures 
uniform, standardized grades and more accurate 
planting. Henning Hybrids are stiff-stalked. 
The fact that hybrids are stiflFer stalked and stand 
up has convinced many farmers that Hybrid 
Corn is the Corn to grow. The hybrids that we 
are offering to the farmers are noted for their 
stiffness of stalk. 
Henning Hybrids Are Certified by 
Ohio Seed Improvement 
Association 
Henning’s Certified Hybrids are your guarantee 
that you are obtaining seed of superior quality. 
There are many steps in the production of 
hybrids where the quality may be low'ered. The 
inbred lines must be properly selected and 
handled. The single crosses must be carefully 
isolated and planted in such a manner that you 
will secure the best cross. They also must be 
properly and quickly de-tasseled so as to give 
the buyer of the seed the best quality. 
Henning Hybrids are produced with exactness. 
W e spend extra money at de-tasseling to get all 
tassels before any pollen ripens and falls. This 
is very important if you are to get top quality. 
Certified Hybrids produced by Henning Bros, 
assure you of this quality and carefulness in 
production. Our hybrids, when harvested, are 
dried to 14 per cent moisture or less, thus assur¬ 
ing high germination and quality seed. 
Will you please send me your Seed Catalog? I 
bought some seed from you a few years ago and I must 
say that I never had better results with seed. They 
were first class. I w'ould like to give you another order 
and would be pleased to recommend them to anyone ^ 
interested in a garden and real quality seeds.— Mrs. i

Henning Hybrids Are 
High-Yielding 
The hybrids previously described have been 
tested time and time again in exhaustive tests 
at the Ohio Experiment Station and their super¬ 
vised test-farms. In Ohio, all hybrids that are 
released and sold as certified have had to meet 
and pass such testing. That is why our hybrids 
are proved. They have ro be all-round hybrids 
of proved and tested performance, with an 
established superiority of from 10 to 25 per cent 
in combined yield and standing ability over 
good, open, pollinated varieties of the same 
seasonal requirements. 
W^e are producing the better hybrids for the 
northern part of Ohio, southern Michigan, north¬ 
ern Indiana, Pennsylvania, certain areas in 
southern New York, New Jersey, Maryland, 
Delaware, and northern West Virginia. 
Henning Hybrids, Ohio-Certified, Meet These Requirements 
1. An officially established superiority of at 
least 25 per cent in combined yield and 
standing ability over good open-pollinated 
varieties of the same seasonal require¬ 
ments. 
2. Are produced from certified, known pedi¬ 
gree, pure foundation seed stocks. 
3. Are produced in properly isolated and 
properly de-tasseled crossing plots. 
4. Seed dried promptly to 14 per cent moisture. 
5. Germination not less than 90 per cent of 
strong sprouts. 
6. Seed so graded as to be planted accurately 
with the proper plates. 
7. Crossing plots officially inspected by the 
Association three to five times during de- 
tasseling and seed officially inspected and 
sampled for moisture and germination. 
8. Seed graded with the Buckeye Hybrids, 
Inc., grader.
