Corn trials conducted by South Dakota State College with whom we cooperated. 
Increased Yields 
IOWA HYBRID 931 
The earliest Iowa station double cross in com¬ 
mercial production, made up of 4 inbred lines, best 
adapted for the second tier of Iowa counties, but 
has been used successfully in the northern two tiers. 
When compared for seven years with the average 
of the open pollinated strains in the northern sec¬ 
tions of the Iowa Corn Yield test, 931 yielded an 
average of 10.1 bushels to the acre more, and in 
every comparison had a stronger stalk. Has done 
very well in Minnehaha County, South Dakota, and 
we strongly recommend this variety for the southern 
and eastern counties of South Dakota. 
IOWA HYBRID 939 
This is one of the best adapted hybrids for tiers 
of counties two, three, and four, when numbered 
from the north or central Iowa. There is more Iowa 
Hybrid 939 grown in the United States than any 
other hybrid variety. Its wide range of adaptability 
enables it to be grown from coast to coast. It has 
extreme lodging resistance and yielding ability. The 
shanks are very short, and it is adapted to either 
hand or mechanical picking. The seed is especially 
resistant to cold, wet soil, and can be planted earlier 
than most hybrid corn. Unlike many hybrids the 
grain is not flinty and is therefore ideal for either 
feeding or cash sale purpose. We recommend this 
variety for the following three counties in South 
Dakota, Yankton, Clay and Union. 
Our Mr. Lyons inspecting a field of Hybrid Corn, E 4 
variety, grown IV 2 miles north of Mitchell. This Hybrid 
Corn caused quite a sensation as it was the only corn to 
mature for miles around in this section. This grower also 
raised melons grown from our seed. It takes hardy northern 
grown seed to stand adverse conditions. 
TURNER'S E4 
E 4 is our earliest Hybrid corn. In fact, it is one 
of the earliest hybrids on the market. It may be 
planted as late as the first week in June and still 
produce an excellent crop of corn. It has a five- 
year record in the Corn Yield Contest of yielding 
14.7 per cent more corn than the average open pol¬ 
linated varieties. It is not a large ear corn but will 
produce one to two medium sized ears per stalk 
and may be planted three to four kernels per hill. 
It stands up fairly well and is adapted to use in a 
mechanical picker. We strongly recommend this 
variety where an early corn is desired. 
MINHYBRID 403 105 DAYS 
Minhybrid 403 matures in about 105 days, and 
has about the same maturity as Minhybrid 301, 
Golden Jewel, Early Murdock, and Silver King. It 
has the advantage over 301 in that it stands up 
better and is more resistant to smut. It will out- 
yield open pollinated varieties 10 per cent to 
20 per cent according to recent tests. It produces 
a long smooth dent, sixteen to twenty rowed ear, 
high quality grain. This variety is adapted to 
southern Minnesota, Wisconsin, South Dakota and 
similar territories and northern Iowa. It is the 
latest development of the Minnesota Experiment 
Station, and is the result of combining two early 
maturing inbred lines from Minnesota 13 with two 
late inbred lines from Keid’s Yellow Dent. 
HILLDROP KERNELS OF HYBRID 
CORN 
We have a very good stock of Hilldrop Kernels 
of most varieties of our Hybrids and for those who 
have suitable planter plates to handle Hilldrop Ker¬ 
nels, we can quote very attractive prices. This 
presents a very favorable opportunity to try out 
Hybrid Corn at a very moderate price. Hilldrop 
Kernels will give just as good results as Edgedrop 
as the breeding is there just the same. Implement 
companies such as John Deere, International Har¬ 
vester Company, etc., have manufactured plates to 
use for hill drop corn. See your nearest imple¬ 
ment dealer and have him order the plates for you. 
We will be glad to mail you samples of Hybrid Corn 
so you can have plates made to suit.
