Picks "Clean" With Machine ALL DAY 
Pioneer 322 is ideal for both machine pickers and 
hand huskers. It picks clean with mechanical pick- 
ers all day, even in afternoons after husks have 
dried out. 
And it breaks easy for hand huskers.

Here’s what the Iowa Agricultural Experiment Station 
says about Pioneer 322 in the 1940 Iowa Corn Yield Test 
Report (Bulletin P19): 
“Pioneer 322 has the highest yield for 5 years and stands 
i near the top for the 4, 3 and 2-year period in this section 
(Northern Iowa). This hybrid has the lowest percentage 
of lodged plants of any hybrid entered in the Northern 
Crt Section for 5, 4, 3 or 2 years.” 
Pioneer 322 also holds the highest yield ever produced 
in the Minnesota Corn Yield Trials—I21 bushels per acre, 
made in 1939.

4 "FIRSTS" IN NORTH CENTRAL SECTION 
5-Year Average 


In the 5-year results of the official Iowa Corn Yield 
Test, in North Central Section, Pioneer 322 ranks first for 
yield, first for lodging resistance, first for resistance to ear 
dropping, and first for resistance against damaged grain. 
UNEQUALLED FOR RESISTANCE TO EAR DROPPING 
Strong, slender shanks hold Pioneer 322 ears on the stalk. Among all hybrids 
tested in Northern Iowa for 5 years and for 4 years, Pioneer 322 is unequalled 
for resistance to ear dropping. In the 3-year results, only one other hybrid (also 
Pioneer corn) equals its record. In the 2-year results, only two other hybrids ° 
are as good and both average approximately 10 bushels per acre less in yield. 
MEDIUM-SOFT KERNELS — HIGH SHELLING PERCENTAGE 
RESISTS SMUT AND DROUGHT 
The ears run medium in length, are well dented, contain medium-soft starch, 
have deep kernels, small cobs. Generally overruns measured cribs 5 to 15 per 
cent when shelled. Resists smut excellently. Thrives well under drought condi- 
tions, its long, hardy roots reaching deep into the ground for needed moisture. A 
hybrid that yields more corn than its field appearance indicates. Farmers report 
they ‘don't know where all the corn comes from” when they harvest Pioneer 322. 
A dependable, general purpose corn that delivers crop satisfaction and profit year 
after year. 
FED TO INTERNATIONAL "GRAND CHAMPIONS" 
POPULAR AS FEEDING CORN 
This hybrid is popular as feeding corn throughout the upper half of 
Iowa. Among the feeders who use Pioneer 322 are the Schmidt Bros., of 
Delmar, Iowa, whose carlot entries of Angus cattle have won “Grand 
Champion’”” awards at the International Livestock Exposition three times 
in the last four years (1937, ‘39, ‘40). 
All carlots of steers exhibited by these aggressive feeders of show and 
market cattle are fed out and finished on Pioneer 322 and other Pioneer 
hybrids.
