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. 



Ji should he 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 nol he expected. To the extent that the 

 weeds developed or were unhindered in their growth would tho corn 

 ground approach a grain stubble in the eondition of the seed bed. 

 If they matured seed, further damage might be done by their growth 

 in the succeeding crop.
