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 groat 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 cither of results from different meth- 

 od- or <>f these CTOps with others. 



At Tucumcari i.h<- work lias not boon carried on for a sufficient 

 length of time f<> obtain averages that warrant the drawing of con- 

 i ]u ions. Results from Akron, Hays, and Tneiiinoari are, therefore, 

 n«.t, in. hided in the tables.
