A Reeommenda* 
tien of Hybrids for 
Planting in 1940. 
By the Ohio Agricultural 
Experiment Station and Ag¬ 
ricultural Extension Serv¬ 
ice of Ohio State Univer¬ 
sity. On the accompanying map 
showing “Adaptation Areas for Com 
Hybrids in Ohio/' locate the farm 
for which hybrids are to be pur¬ 
chased, then note below the certified 
hybrids recommended for different 
conditions in that area. 
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 out- 
yield 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 weight 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.

In each group of recommendations in the above table the hybrids are arranged in approximate order of 
maturity—the earliest first. However, the maturity differences are often very slight and may be insignificant 
under some conditions. For instance, the differences in maturity between la. 939, and W17 are slight and 
often not evident.
