HYBRID 
CORN increases yield 15% to 25%, is resistant to smut, rust an 
Aa eS as 
wilt; has deeper and more 
vigorous root systems, therefore less affected by drought or severe wind. 
GROW HYBRIDIZED VARIETIES 
OF KNOWN ADAPTABILITY 
Plant Hybrid Corn because of the certainty of a 
better yield and much better quality. It is impor- 
tant to plant only seed proven to be adaptable to 
this section and grown by experts. 
Hybrid corn is 
not necessarily all desirable. The process is expen- 
Sive, highly technical and requires the skill of a 
plant breeder. Manns’ hybridized corns have been 
grown by experts and have proven profitable for 
this section. 
Please Note—lIt is useless to try to save seed 
from hybrid varieties of corn. They must be newly 
developed each year.
