GRAIN-SORGHUM EXPERIMENTS IX OKLAHOMA. 
59 
These data indicate that Dwarf Yellow milo is a wvy adaptable 
crop, giving an extreme difference of only 4.6 bushels in the average 
acre yield in the five years from stands varying from 20,000 to 
4. SCO plants per acre spaced in rows 44 inches and 88 inches apart. 
In 1918. an unfavorable year, milo in 88-inch rows outyielded that 
in 44-inch rows, and again in 1920 the 88-inch rows were slightly 
better. In average yields for the 5-year period the 44-inch rows 
lead except where the plants were spaced 13 inches apart, or approxi- 
mate!}* 11,000 plants to the acre. The best spacing is one plant to 
each IS to 24 inches in rows 44 inches apart or one to each 9 to 12 
inches in 88-inch rows. These rates approximate 6,000 to 8,000 
plants to the acre. There appears to be a slight disadvantage 
rather than advantage in growing milo in 88-inch rather than in 
44-inch rows. 
SUNRISE KAFIR. 
The spacing experiments conducted with Dwarf Yellow milo were 
duplicated with Sunrise kafir. The object and nature of these experi- 
ments have already been explained; hence only the results need be 
considered here. The data for the spacing experiments with Sunrise 
kafir are given in Tables 28 to 32, inclusive.

apart at the Woodward Field Station during the 5-year period from 1917 to 1921, 
inclusive. 
[In the statement of yield of grain per acre, the bushel is rated at 60 pounds.]
