Wheat on disked corn ground has given consistently high yields. 
This, together with the low cost of this preparation for wheat, has 
resulted in its uniformly showing the greatest profit per acre at those 
stations where wheat has been produced at a profit and the least loss 
at those stations where wheat has been produced at a loss by all 
methods. The only exception to this is at Dalhart, where yields have 
been so low as to be of little practical moment. The realization of 
these profits depends, of course, upon the profitable production of 
corn, in competition with other crops, as a general farm crop. 
It should be borne in mind that at all stations disking corn ground 
as a preparation for all small-grain crops has been done on corn 
land kept free from weeds. If weeds were allowed to develop in the 
corn, similar results should not be expected. To the extent that the 
weeds developed or were unhindered in their growth would the corn 
ground approach a grain stubble in the condition of the seed bed. 
If they matured seed, further damage might be done by their growth 
in the succeeding crop.
