CORN, MILO, AND KAFIR IN THE GREAT PLAINS AREA. 
11 
have produced fodder each year, but in only one year has there been 
a creditable production of grain. 
The differences in the yield from different methods have been com- 
paratively small. Summer-tilled land shows a small increase in the 
yield of both grain and stover over all other methods. Fall plowing 
has proved a somewhat better preparation than either spring plow- 
ing or listing. Subsoiling has failed to increase yields over fall 
plowing. 
Listing shows a small profit of 67 cents per acre. All other 
methods show losses ranging from 19 cents per acre by fall plowing 
after corn to $2.85 on summer-tilled land.

RESULTS WITH MILO AND KAFIR AT INDIVIDUAL STATIONS. 
Milo is undoubtedly the leading grain crop grown in this section 
and has given surer and better grain yields, on the average, than 
any other crop grown at the stations included in this study. Two 
types of this crop are commonly grown, namely, Standard and 
Dwarf. The Standard type grows a stalk averaging about 4^ feet in 
height, depending upon seasonal conditions, while the Dwarf prob- 
ably will not average over 3 feet. Differences in yield due to 
seasonal conditions so far overshadow any differences in type that 
it is almost impossible to draw any definite conclusions as to just
