CROP PRODUCTION IN THE GREAT PLAINS AREA. 



11 



the crop on summer-tilled land. The increase in yield at all of these 

 stations except Hays has been sufficient to justify the use of this 

 method for winter wheat if the results are to be compared with those 

 from wheat stubble plowed hi the fall. 



At Akron the greatest profit has been realized from the growth 

 of the crop on disked corn ground. At Hays land treated with the 

 lister after harvest and land subsoiled have given decidedly the 

 greatest profits. 



The yields following the plowing under of rye or peas for green 

 manure have approached, but in no case equaled, those on summer- 

 tilled land. The greater cost of the method removes it from com- 

 petition with other methods. 



OATS. 



In Table IV are brought together for the several stations the 

 average yields of oats and the cost of production data as grouped for 

 study under different methods of preparation, showing the profit or 

 loss per acre for the average crop for each method for which it has 

 been computed at each station.
