PUBUSHED IN THE INTEREST OF BETTER SEEDS _ 1 
Vol. 16 CORNELI SEED COMPANY, ST. LOUIS, MISSOURI Special Issue No. 1 
ARE THESE WORTH 75/ PER ACRE? 
Well, just read them over. We think you 'will agree that any 
one of them may be worth several times that amount. Yet that is 
the cost per acre to plant Keystone Hybrid corn, which can do 
all of these things for you. 
increase Yield — Grow your corn requirements on less land 
and build up those extra acres with legumes. 
10 to 25% less land needed. 
Resist Drought —Stays green longer during dry weather, 
greater certainty of a crop. 
Resist Wind —Stands erect after maturity, means less back¬ 
breaking work during shucking time, and 
saves loss from lodged corn. 
Uniformity — Every stalk bears an ear at uniform height, 
making possible the efficient use of me¬ 
chanical pickers or greater ease of hand¬ 
picking. 
Uniform Maturity —Ripens evenly so that all corn is ready to 
store before bad weather. 
Users of Keystone Hybrids take advantage of ail of these points 
because Keystone Hybrids are top performers in their areas of 
adaptation; because Keystone Hybrids are sold only where they 
are adapted; and because their breeding, production, and 
processing assure top yields of high quality grain. Why take 
chances with hybrids of questionable adaptation when Keystone 
Hybrids cost no more and are produced and sold where they 
yield the most.
