THE GROWER YOU DEAL WITH 
N ORTHRUP, KING 5c CO. undertook the improvement and production of 
Seed Com more than fifty years ago. Experienced field men, a definite 
breeding program, and modern equipment for handling crops, have all 
combined to produce seed of superior quality. The breeding work has been 
under the direct and 
personal supervision 
of a well trained 
staff. 
Stock seed is the 
fundamental basis of 
all seed production. 
Northrup, King & Co. 
has experienced An Isolated Crossing Field 
men who know Corn 
and who follow the 
Crops through seeding, growing, harvesting, drying, shelling, milling, hand¬ 
picking, and bagging for shipment. Ample trial grounds are maintained for 
testing new introductions, new varieties, and competitive stocks. New varieties 
are developed in carefully operated breeding plots. Throughout trial and 
breeding work, all data and information is accurately and carefully obtained. 
The basic stock seed is pro¬ 
duced in isolated and care¬ 
fully handled plots. 
Although "Hybrid" Sweet 
Corn is of quite recent intro¬ 
duction, Northrup, King 6c 
Co. has been working on in- 
breds since 1922. The final 
success of "Hybrid" Corn 
depends upon the ability of 
the seed grower to keep in- 
breds true and pure. Only, 
experienced and well 
trained men can do this. 
Methods of "selfing" these inbreds and planting them in isolated plots for 
"sibing" protects Northrup, King 6c Co.'s customers. Maintaining a definite 
breeding program is most essential.
