HYBRID SEED CORN PAYS 
Even with feed corn prices as low as at the 
present time, Hybrid seed pays itS way many 
times over. First, it definitely will outyield your 
open pollinated varieties. Second, it has a 
much stronger root system which with stiffer 
stalk resists lodging much more than your old 
kinds. Many folks would buy Hybrid seed for 
this advantage alone. Third, with ears nearly 
the same height all over the field, husking is 
definitely easier if by hand and will not knock 
off as many if done by machine. Fourth, adapted 
Hybrids mature better and are generally in better 
condition to crib.
