PRICES ON REGISTERED CORN FURNISHED ON REQUEST 
Colorado Registered Corn. Increases the yield of corn. 
As corn is Colorado’s most important crop from the 
standpoint of acreage and produce yield, it would seem 
that it would be good policy to buy pedigreed seed, which 
has been bred for adaptability and yield over a long 
period of years. One strain of Colorado Registered Corn 
has made an average yield of 73.3 bushels per acre in a 
five-year yield test at Fort Collins experiment station.
