The benefits of planting Hybrid Corn over open pollinated corn are much larger yields, both in grain and for en- 
silage purposes, strong roots, and evenness of ears on the stalk. Stalks stand up much better. 
This year we will again feature Colorado grown State Registered and sealed Hybrid Corn. This means that the corn 
is grown under rigid rules and supervision. Stock seed must be of known and proven parentage. Fields have to 
be isolated from all other corn and carefully detasseled at the proper time. 
Germination must be high to rate Blue Tag. 
Colorado Grown Corn is adapted to this region.
