CROP PRODUCTION IN THE GREAT PLAINS AREA. 19 
in actual loss at Judith Basin, Dickinson, Edgeley, Belle Fourche, 
Hays, Garden City, and Amarillo. 
Another fact shown is the greater profit derived from the growth 
of corn after corn over corn after small grain at Akron and North 
Platte, and from corn following small grain over corn following corn 
at Huntley. 
Listing has been tried at nine stations. Except at Scottsbluff and 
Akron it has been the most profitable method under trial. As has 
been pointed out, the relative profitableness of this method has been 
largely due to its low production cost rather than to increased yields. 
A careful reading of the data given in Table VI will show that corn 
can not be profitably grown as a grain or cash crop in large portions 
of the Plains. At only 5 of the 13 stations have the grain yields been 
sufficiently large to indicate a possibility of the crop being profitably 
produced for the grain alone. At Huntley, Dickinson, Scottsbluff, 
North Platte, and Akron, enough grain has been produced by some 
methods to pay the cost of production and show small profits. Taken 
as a whole, however, the data show that in order to realize the full 
profit corn should be considered as a feed crop. To pay the cost of 
production, in many sections it is necessary to utilize the roughage 
produced. When this is done, the corn crop shows a profit at all sta- 
tions except Garden City and Amarillo. It should therefore occupy a 
permanent place in the rotation except in the extreme southern por- 
tion of the area, as it leaves the soil in good condition for the crops 
that follow it. 
MILO AND KAFIR. 
The area to which milo and kafir are adapted has been shown in a 
previous publication. 1 Experimental work in methods of production 
of these crops has been done at Akron, Colo.; Hays and Garden City, 
Kans. ; Dalhart and Amarillo, Tex. ; and Tucumcari, N. Mex. 
The latitude and altitude at Akron combine to make conditions 
generally unfavorable for either milo or kafir. In the production of 
grain they can not compete with corn. In the production of forage 
they can not compete with sweet sorghum. 
At Hays both milo and kafir are of great value. The small area of 
the plats in the experimental work has subjected them to influences, 
such as ravages of insects, that are not generally experienced under 
field conditions. The data that have been obtained are not sufficient 
to permit adequate comparison either of results from different meth- 
ods or of these crops with others. 
At Tucumcari the work has not been carried on for a sufficient 
length of time to obtain averages that warrant the drawing of con- 
clusions. Results from Akron, Hays, and Tucumcari are, therefore, 
not included in the tables.
