There is no magic in planting just any hybrid. Hybrids 
good, bad and indifferent. Be sure the one YOU 
are 
plant is well suited to your farm. Make certain that it 
has been performance-tested for yield, guality, hardiness, 
ality HYBRIDS 
insect resistance and ability to stand erect until after 
harvest. And buy your needs from a concern that oper¬ 
ates on large enough scale to remain a reliable source 
of known quality seed every year.
