FIELD SEEDS 
ALFALFA 
CULTURE—Alfalfa Seed may be sown either in spring or in 
fall at the rate of 12 to 20 pounds per acre. Sow with oats, 
barley, field peas 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 of 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. 
COMMON ALFALFAS—Most Common Alfalfas originate from 
seed brought from Spain to Chile and, in about 1850, to Cali- 
fornia. From California seed moved in all western states. 
Colorado Common, Utah Common. Idaho Common, Montana 
Common, and other Common Alfalfas are believed to be 
regional strains from this seedstock. 
The Common Alfalfas can often be purchased by state 
origin but differences between them are insignificant. It is 
actually more sound to think of them in terms of region 
_ rather than state of origin. 
BUFFALO ALFALFA—A selection of Kansas Common, that 
has been chosen for its resistance to bacterial wilt. It is 
winter hardy and is recommended for Colorado and for 
high altitudes. 
IMPORTED ALFALFA—Stained 10% Red to meet Govern- 
ment regulations. Similar to Colorado Common, 
RANGER ALFALFA—Ranger is a multiple strain variety 
carrying about 45% Cossack, 45% 'Turkistan, and 10% 
Ladak blood. Ranger is variable in habit of growth and 
flower color and is classified within the variegated group. 
It is superior to Ladak and Cossack and equal to Grimm in 
rapidity of recovery after cutting. It is slightly more sus- 
ceptible to leaf-spot disease than Grimm, but is equal to it 
in cold-resistance. Ranger is the most wilt-resistant Alfalfa 
available, and, even though it may yield slightly less per 
season than Grimm, longer life stands more than offsets 
this disadvantage. 
GRIMM ALFALFA—The hardiest of the hardy alfalfas and 
differs from the domestic or common variety in that it hasa 
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. Very hardy and will produce a fine hay crop. 
MEEKER BALTIC—This hardy strain is produced in the same 
district in Colorado as the Moffat Grimm. It is of the Grimm 
type and by some authorities is considered the hardiest and 
most productive variety. 
LADAK— Originated in India, is very winter hardy and shows 
more variegation than most other varieties in this group. It 
produces an exceptionally heavy first cutting, and, even 
though second and third cuttings may be light, total seasonal 
yields are often higher than those of other varieties. Ladak 
is resistant to leaf disease, retains leaves well, and there- 
fore produces hay of high quality. Ladak is more resistant 
to bacterial wilt than Grimm.
