often exceed those of Ladak. However, there seems to 
be little difference in the total annual yield. 
Ladak has a tendency to become dormant early in 
the fall. It is relatively free from leaf disease, retains * 
its leaves, and makes hay of fine quality. 
In many tests Ladak has proved superior to all others 
for the cold and dry conditions found in the Northern ~ 
Great Plains and it has also given good results under 
irrigation in the Northwest. Even as far south as Man- 
hattan, Kansas, yields obtained from Ladak have com- 
pared very favorably with those from other alfalfas. 
Where wilt is prevalent in this general region, Ladak 
has considerable advantage over other variegated and 
common varieties. 
RANGER 
Ranger is a synthetic variety, having been made from 
selections originating from the varieties, Cossack, Turk- 
istan, and Ladak. It shows considerable variability, both 
in habit of growth and flower color. The plants vary 
from those that lie fiat on the ground to those that 
grow upright. It has rapid recovery from cutting. To 
both leaf-spot diseases and leafhopper yellowing, it is 
susceptible. 
High yielding and wilt resistant, Ranger’s real value 
is for long time rotations, pastures and other places 
where more than three years is expected of the stand. 
Ranger is distinctly wilt and cold resistant, superior in 
seed production, and equal to Grimm in hay tonnage. 
ALFALFA AND CLOVER SEED GERMINATION is 
higher when the combine cylinder speed is kept low. 
EXxperiments reveal that germination can frequently be 
increased as much as 10 percent by merely reducing 
cylinder speed. For maximum germination, the following 
speeds have been found best for cylinders of various 
diameters: 18-in.—850 rpm; 20-in.—765 rpm; 22-in.—695 
rpm; and 24-in.—635 rpm. These same tests also show 
that much seed can be saved by slowing down the travel. 
speed of the combine. Test showed 10 pounds per acre 
of seed were lost at .8 miles per hour; 35 pounds at 1.2 
miles per hour; and 74 pounds at 1.4 miles per hour.
