NURSE CROPS 
Use only those that mature early. Seed them at a 
moderate rate. Manage the nurse crop to prevent com- 
petition for moisture. Rate of seeding of the nurse crop: 
sow 4 to 8 pecks per acre of Oats or one-third to one-half 
normal rate for other nurse crops. In regions of limited 
rainfall, the use of a nurse crop has proven disas- 
trous and is not recommended unless cut early for hay. 
RATE OF SEEDING 
12 to 15 pounds alone or 5 to 8 pounds in grass mix- 
tures. 
On poor soil, where weeds are likely to be trouble- 
some, the best rate of seeding is 15 pounds per acre. 
Under more favorable conditions, 10 pounds are ample. 
ALFALFA 
Use Legume Aid when planting Alfalfa Seed.

GRIMM 
This is the best known member of this group in the 
United States. It is difficult to tell Grimm from Com- 
mon alfalfas. In the drier areas where it is grown it 
will show great variation in flower color. 
Very hardy, Grimm has been recommended particular- 
ly for all Northern States. But because of its suscepti- 
bility to bacterial wilt, it is becoming less popular where 
this disease is prevalent. A good seed producer; it is 
useful in short rotations. It produces yields equal to 
Ranger until wilt begins damage. 
COSSACK 
It is a hybrid between the common and yellow- 
flowered alfalfa. The flowers show more yellows and 
whites. Adapted to the same growing conditions as 
Grimm, it has not shown evidence of being appreciably 
superior to Grimm under most conditions. Extremely 
winter-hardy, it is second only to Ladak in forage yields 
after the first two years. 
LADAK 
Ladak alfalfa was obtained from India in 1910 and 
is predominantly yellow-flowered. Ladak’s one outstand- 
ing characteristic is its ability to make an exceptionally 
heavy first crop. This makes it especially’ valuable 
where only one cutting is normally obtained. It recovers 
slowly and the second and third crops of other varieties 
often exceed those of Ladak. However, there seems to 
be little difference in the total annual yield.
