Plant High Germinating Seed! 
Recent University of Minnesota studies have 
shown that improper storage of soy beans causes 
heating’’ and ‘also injurious molds, which re- 
Sult in poor germination and weak seedlings. 
If beans have been stored when high in moisture, 
or where air is moist and circulation poor, the 
result is often ‘‘heating’’ of the beans, ren- 
dering them useless for seed.

tion for your crop. Insist on the highest quality 
seed stocks, and government recommended, early 
varieties, that are safe for your section and 
suited to early combine harvesting in Minnesota. 
Our seed stocks have been carefully tested to 
insure low moisture content before storage, and 
are then tested for high germination.

same treatment as corn, 
most any kind of soil, shallow peat or sandy 
loam, and even ground containing too much 
alkali for corn. Do not plant Soy Beans too 
early, about corn planting time is right. 
Inoculate seed with Nitragin (below) 
plant as follows: 
1. In ordinary 6 in. row8 with a grain drill, 
using 90 to 120 lbs. of beans per acre. 
2. In 12 in. rows, using a grain drill and 
plugging up every other drill, using 80 
to 90 Ibs. per acre. 
3. In 21 in. rows, using a corn planter with 
a bean attachment, the planter being set 
at the regular distance of 42 in. and the 
rows straddled. Plant about 70 to 75 lbs. 
of beans per acre, 
Soy Beans require about the

36 and 42 in. apart and cultivated. Plant 
35 to 45 lbs. of beans per acre. 
5. Soy Beans may also be broadcast, using 
about 90 to 120 lbs. per acre. 
Soy Beans for Seed 
The seed crop is quite profitable. The seeds 
broken or split in threshing can be fed to live- 
stock. For seed, the Soy Beans~should be cut 
with a grain binder, while the dew is still on 
them, so they will not shatter. They can be 
threshed without much curing, if the seed is 
spread out so it cannot sprout in the bins. 
Soy Beans may be turned under in the fall, 
thereby enriching the soil and making it mellow 
and easily tillable. 
The Most Profitable Varieties for the North 
RICHLAND 
Developed by Purdue Experiment Station, 
Very popular in Northern Iowa because of its 
early maturity, high yield, standing ability, and 
high oil content. It grows 28 to 35 inches high, 
stands up well for combine harvest. Seed is 
medium sized, straw yellow. Recommended by 
Minnesota Experiment Station for hay, in the 
Southern Zone. Recommended for Northern 
Iowa by Iowa Experiment Station. 1946 U.S.D.A. 
data on 6 years testing shows Richland aver- 
aged 27.5 bushels per acre yield, with 41.1% 
protein, 20.2% oil of 128 iodine number. See 
Blue Figure Price List. 
Developed at University Farm. MHabaro’s 28 
to 35 inch plants are highly resistant to lodging. 
Seed and hay yields run about as high as any 
variety tested at the Waseca Station. Recom- 
mended for seed and hay production in Minne- 
sota’s Southern Zone, South Central Zone and 
the southernmost two-thirds of Central Zone. 
1946 U.S.D.A. data on’ 8 years testing shows 
Habaro averaged 27.9 bushels per acre yield, 
ranked first in protein content with 43.3%, oil 
content 18.6%, and iodine number of oil 133. 
Recommended by Minnesota Experiment Station. 
See Blue Figure Price List. 
OTTAWA MANDARIN 
An improved Mandarin from Dominion Ex- 
periment Farm, Ottawa. Plants grow 27 to 33 
inches high, with good standing ability, purple 
flowers and yellow pods. with’2 to 4 buff seeds, 
1946 U.S.D.A. data on 3 years testing shows 
Ottawa Mandarin averaged 27.3 bushels per 
acre yield (highest in its maturity group), 
42.6% protein, 19.2% oil of 131 iodine number. 
Ottawa is higher in yield and oil than Mandarin 
Wis. 507. Ottawa strain is recommended for seed 
and hay production in Southern, South Central, 
Central, and North Central Zones, and for hay 
only in Northern Zone. When planted late 
(June 20) in Southern Zone, Ottawa ripened 
and produced 25 bu. per acre, Recommended by 
Minnesota Experiment Station. See Price List. 
EARLYANA 
Developed by Purdue Experiment Station. 
Plants are semi-whiplike, with the pods along 
the main stem. Lower branches and pods are 
borne well off the ground. Flowers are purple, 
pods are brown, fairly large, with two, three and 
occasionally four medium sized seeds. Seeds 
seldom shatter when ripe, are straw yellow with 
brown speck on a pale hilum, In Northern Iowa 
tests, Earlyana yielded two bu. per acre more 
than Richland, proved four days earlier and 
better adapted to thinner soils, Recommended 
for Northern Iowa by the Iowa Experiment Sta- 
tion. 1946 U.S.D.A, data on 38 years testing 
shows Earlyana averaged 27.7 bushels per acre 
ield, with 42.5% protein, 19.6% oil of 135 
iodine number. See Blue Figure List, 
MANCHU, Wisconsin 606 
Developed by Wisconsin Experiment Station, 
Similar to Habaro in yield, and maturity, with 
fairly good standing ability. Averages 1.5% to 
2% higher in oil content than Habaro. Adapted 
for seed and hay production in Minnesota’s 
Southern Zone, South Central Zone and Southern 
two-thirds of Central Zone, and for hay only in 
the Northern third of Central Zone, and in North 
Central Zone. 1946 U.S.D.A. data on 3 years 
testing shows Wis. Manchu 606 averaged 27.6 
bushels per acre yield, with 41.4% protein, 
19.9% oil of 135 iodine number, Recommended 
by Minnesota Experiment Station. See Blue 
Figure List. 
MANCHU, Wisconsin No. 3 
A Wisconsin Exp.~ Station selection from 
Manchu. Grows 30 to 85 inches high. Similar 
to Manchu Wis. 606 in standing ability and a 
few days later in maturity. Seeds are medium 
sized, straw-yellow with black hilums, 1946 
U.S.D.A. data. on 8 years testing shows 27.9 
bushels per acre yield (highest in its maturity 
group), with 41% protein, 19.9% oil with 135 
iodine number. Recommended by Minn. Experi- 
ment Station for seed and hay production in 
Southern Zone, and for hay production only in 
South Central Zone, and Southern Two-Thirds of 
Central Zone.
