Corn Growers should consider seriously 
the growing of Hybrid Corn, as the Hybrids 
have proven their merits in all corn-growing 
sections, especially where moisture conditions are favorable. 
In selecting the Hybrid for your conditions, be sure to select 
a Hybrid from a reliable source and of the right maturity. 
Wm. Jacques, the pioneer and largest grower of Hybrid 
Corn in the North, advises to plant three different maturities 
of Hybrid Corn. When several good hybrids are compared 
over several seasons, you learn a surprising and important 
fact. The variety that yields the most this year may yield 
the least next year. This year may have favored the corn of 
one maturity as against the corn of another maturity. Next 
year the conditions may be reversed. Don’t choose your crop 
for next year’s planting based on the performance in one sea- 
son of any one hybrid. Choose only Hybrids that have shown 
a good average performance over several seasons and choose 
three different maturities of these. 
Plant Jacques PROVEN HYBRIDS because— 
_ (1) Every Jacques Proven Hybrid has proven its superior- 
ity in not just one season, but as an average of at least three 
seasons before it is offered for sale. 
(2) You can get Jacques Proven Hybrids in dependable 
maturities varying by 5 days, from 80 to 120 days. And 
here’s something else! 
(1) Your Jacques Proven Hybrid Corn shells out more 
corn per bushel of ear corn. It yields even more than the 
wagon box shows. 
: (2) Your Jacques Proven Hybrid Corn dries out fast, goes 
into the crib with less water in cob and in kernels. 
(3). If you plant all late corn you run the risk of a soft 
crop in a short cool season.
