AS EARLY OR EARLIER THAN PIONEER 355 
Pioneer 358 ears are moderately rough and have medium- 
soft starch kernels. It is excellent for hand picking because 
the ears hang at a convenient height and break off easily 
for the husker. This variety shows a distinct tendency toward 
producing only one ear per stalk. It matures, yields, and 
stands up almost exacily the same as Pioneer 355, but has 
shorter shanks and is more resistant to smut than 355.

PIONEER 365 
ABOUT 5 DAYS EARLIER THAN PIONEER 355 
Pioneer 365 matures about five days earlier than Pioneer 
355. Considering its earliness, 365 produces an unusually 
high yield and stands up well in the field. In trial tests, it 
has regularly outyielded hybrids that mature a week later. 
It has very strong roots and stiff stalks, and medium-hard ears 
with smooth dent. The ears are carried quite low on the stalk. 
FOUR MORE New OUTSTANDING HYBRIDS 

PIONEER 353-A 
ABOUT A WEEK EARLIER THAN PIONEER 322 
This hybrid appeals to farmers who like single eared corn 
with long, rather rough-type ears. Pioneer 353-A produces 
attractive corn that’s pleasing to the eye—both in the field 
and in the crib. It possesses both high yielding ability and 
excellent lodging resistance. You will find 353-A quite similar 
to 353 in most respects. It looks a little better, yields a little 
less, and matures about the same.

PIONEER 373 
ABOUT THREE DAYS LATER THAN PIONEER 355 
Pioneer 373 produces long ears and tends to yield only one 
ear per stalk. The ears hang at a convenient height for hand 
huskers. Medium-length, diseases-resistant shanks hold the 
ears on the stalks. There is very little ear dropping. It has 
strong roots, but on high nitrogen content soil, it has a ten- 
dency to stalk-break in the fall. 



SEASONED VETERANS of The NORTHERN CORN BELT 
PIONEER 355 
HIGHEST AVERAGE YIELD IN SOUTHERN MINNESOTA 
This time tested hybrid has assumed the role of “old reliable” for 
nearly a decade in the Northern corn belt. Year after year, it stands up 
satisfactorily and fills the cribs of ‘Pioneer 355 farmers” with ripe, golden 
corn. It is a “time tested” hybrid that has proved itself profitable for 
both sealing and selling. It matures early—and has a high shelling 
percentage. 
Look up the Official 1940 Minnesota Hybrid Corn Yield Trials—you will 
find that Pioneer 355 is the highest yielding corn tested for four years 
in all three locations in the southern zone. 
PIONEER 324 
HIGH YIELDING—CYLINDER-SHAPED EARS 
Here’s a high yielding hybrid that produces one cylinder-shaped ear 
to the stalk. The big attractive ears are uniform, hold their width well 
to the tip, and show up well in the field. The ears are very resistant 
to shelling in the field when harvested with a mechanical picker. Its 
deep kernels and sound quality ears make Pioneer 324 excellent for 
marketing. It has strong roots, stiff stalks, medium ear height, and 
medium-length shanks. It should be planted quite early on good ground 
in extreme Northern Iowa and in Minnesota. 
PIONEER 322 
OVERRUNS MEASURED CRIBS—HOLDS HIGHEST YIELD IN 
MINNESOTA STATE TEST 
This big yielding hybrid overruns measured cribs 5 to 15% when 
shelled—gives you 5 to 15% more profit than you expect. It has deep, 
sound quality kernels, and small cobs. Pioneer 322 has medium-soft 
kernel starch—and contains more corn, less cobs per bushel of ear corn 
than most varieties. This hybrid has been smashing official lowa and 
Minnesota Yield Test records in the Northern corn belt for the last five 
years. It’s a “banner trophy” winner in the Iowa Corn Yield Test— 
and holds the highest yield record ever made in the Minnesota State 
Yield Test (131 bushels per acre in 1939). In years of short seasons, it 
may be late maturing.
