YELLOW CORN 
Whether you are raising corn for feed or market ... on soil sandy, clay or 
loam ... on hillside or bottom land ... there is a United Number that does 
the job right for you. Varieties pictured above are described at right. 
1E growers of the United 
Hybrid Growers Associa- 
tion joined forces to bring 
together all of their inbreds, 
combine their research and 
breeding into one big organiza- 
tion, increase their production 
facilities, and thus bring to you 
a better hybrid seed corn. 
Farmer after farmer has 
found that it pays him to plant 
a hybrid with that kind of a 
program behind it. You can 
profit too by planting United 
Hybrid Seed Corn. 
About SPECIAL FLATS 
Special Flats are graded per- 
fectly, and so plant easily and 
uniformly. And a bushel of Spe- 
cial Flats contains more kernels 
of corn than Large Flats, plant 
12% to 20% more acreage, save 
you over 50c an acre. 
About ROUNDS 
United’s Rounds are graded 
to fit all standard round plates. 
With a round plate, they plant 
just as uniformly as flats. They 
have just the same breeding as 
flats, come right off the same 
ears, and will give you as good 
a crop. And they save you up to 
2.50 per bu. on your seed corn. 
About BLENDS 
United’s Blends are a scien- 
tific mixture of corns designed 
to lengthen the pollen season to 
20 to 25 days, insuring a good 
set despite weather. You know 
what happens to a single variety 
corn crop when a hot, dry spell 
hits it during ‘its 3- or 4-day 
pollinizing period. Over a period 
of years, United’s Blends will 
out-produce any single hybrid. 
They are especially reeommend- 
ed for marginal growing areas. 
And the seed costs you over 3.00 
a bushel less! . 
Only UNITED is "Kernel Koated" 
Only United Hybrids 
have the famous, secret 
“Kernel-Koated” Seed 
treatment. that protects 
from seed and soilborne 
disease. and 
stimulates growth of 
feeder roots, assures ear- 
lier germination and emer- 
gence. You can cultivate 
3 days earlier, often get 
up to 15 bu. per acre 
extra yield because of 
“Kernel-Koating alone!
