ALFALFA 
The woa- 
derful no¬ 
dules enrich 
the soil and 
insure a big 
crop. 
CULTURE—Alfalfa Seed may be sown either in spring or fall at the rate of 12 to 20 pounds per acre. Sow with 
oats, barley or other grains as a nurse crop, sowing only about half the amount of grain per acre, so that the grain 
will not be too thick to smother out the alfalfa. 
Alfalfa is the great hay crop for America and can be successfully grown in many localities. Alfalfa is of two types, 
the Domestic or Common which has a long tap root which penetrates into the soil for a distance or 8 to 10 feet 
and the Grimm Type, which has a spreading root system. The Grimm type is considered the hardiest although on 
certain soils and in certain localities the Hardy Common varieties will stand extremes of heat and cold equally well. 
All our Alfalfa Seed is especially selected for Adaptability and Hardiness. 
DOMESTIC ALFALFA — Fancy Domestic High Altitude Seed. 
Hardy anywhere, high purity and germination. Post¬ 
paid: 1 lb., 30c; 10 lbs., $2.50; 25 lbs., $5.00. 
DOMESTIC ALFALFA (Dry Land Grown) —Grown in the 
dry plains region without irrigation. Very hardy and

$5.50. 
GRIMM ALFALFA — State Sealed and Certified Seed. Grimm 
Alfalfa is the hardiest of the hardy alfalfas and differs 
from the domestic or common variety in that it has a 
spreading root system instead of the long tap root 
which is sometimes broken when the ground bulges, 
during the spring freezes. Thus causing the plant to 
die. Highest grade seed. 
Grimm, Blue Tag Grade: Postpaid: lb., 40c; 10 lbs.,

that it is genuine Grimm Seed. Postpaid: Lb., 30c; 10 
lbs., $2.50; 25 lbs., $5.50. 
SPECIAL ALFALFA No. 10 —This is a combination con¬ 
sisting of about 40% of Grimm Type Seed and balance 
of Hardy Common Seed. This is an excellent mixture 
where a heavy yield of hay is desired. Not recom¬ 
mended for sowing for a seed crop. Postpaid: Lb., 30c; 
10 lbs., $2.50; 25 lbs., $5.50. 
DAKOTA No. 12 — This variety of Dry-Land Alfalfa has 
given the best results on all types of soil and under all 
climatic conditions. It withstands the extremes of hot 
summers and severe winters and dry high altitudes. Our 
seed was produced on the dry plains of Northwestern 
Nebraska. Postpaid: Lb., 30c; 10 lbs., $2.50; 25 lbs., 
$5.50. 
To insure a good stand of alfalfa inoculation of the seed is necessary. NITRAGIN is the most dependable in- 
oculent. For prices on Nitragin see page 72. 
Clovers 
ALSIKE OR SWEDISH CLOVER —Grows well on low, wet 
land where Red Clover does not thrive. Alsike being a 
perennial, will last for a good many years, either for 
hay or in pasture. It makes fine hay of high feeding 
value. It is very valuable in pastures, especially on wet 
or heavy soil. Sow 6 to 10 pounds of seed per acre if 
used alone. Postpaid: Lb., 30c; 10 lbs., $2.75; 25 lbs., 
$6.25. 
RED CLOVER, Medium— Colorado-grown seed. This is the 
common Red Clover, so extensively grown. It is a bien¬ 
nial in most places, living but two years if allowed to 
seed. It is usually sown early in the spring on winter 
wheat or with oats or barley, but can be sown in Juiy 
or August quite successfully. Sow 8 to 11 pounds 
per acre. The seed we offer is the highest grade. 
Postpaid: Lb., 30c; 10 lbs., $2.75; 25 lbs., $6.25. 
RED CLOVER, Mammoth —Also called “Pea Vine” Clover. 
This variety grows larger and coarser than the Medium 
and is often used for plowing under to enrich the soil 
for which purpose it is very valuable. American grown 
seed. Postpaid: Lb., 30c; 10 lbs., $2.75; 25 lbs., $6.25. 
LESPEDEZA (Korean Clover) —Korean Lespedeza is an 
annual Legume with very fine stems. In general appear¬ 
ance it resembles Alfalfa. It grows about 15 inches high. 
Where the stand is scattered the plants branch pro¬ 
fusely. Where the stand is thick the plants have an up¬ 
right growth like Red Clover or Alfalfa. 
Lespedeza grows on poor soils and increases the fer¬ 
tility as well as improves the physical condition of the 
soil. It is an annual but will reseed itself each year so 
that only one sowing is necessary for a permanent pas¬ 
ture. For pasture about 8 pounds of seed is required per 
acre. On tilled land for hay or for a seed crop 10 to 12 
pounds per acre should be sown. Korean Lespedeza is 
palatable to all classes of live stock, particularly cattle. 
It will stand close grazing by cattle and still set enough 
seed to maintain a stand. Postpaid: Lb., 30c; 10 bs., 
$2.50; 25 lbs., $4.75. 
SWEET CLOVER —The culture of sweet clover is practic¬ 
ally the same as for alfalfa. Sweet clover, however, will 
grow on rough land where alfalfa would not do well. It 
makes an immense growth and if cut before it is too 
ripe makes excellent hay. It is also valuable for pasture 
for hogs, sheep and cattle. Like Red Clover this is a 
biennial and should be renewed every other year. The 
seed may be sown in the late fall and winter, or early 
spring as well as in the summer. For summer sowing 
use scarified .seed. Seed not scarified germinates slowly 
and often lies in the ground a long time without sprout¬ 
ing. Sow 12 to 20 lbs., per acre. ,
