CORN IN THE GREAT PLAINS AREA. 



27 



For this study, Table XVIII has been compiled from the data 

 given in Tables V to XVII, inclusive. The average yields of corn by 

 each method and the profits or losses attending the use of each 

 method, as shown in the detail tables for the several stations, are 

 here assembled. 



Table XVIII. — Comparison of the average yields and profit or loss in the production 

 of corn by different methods at thirteen field stations in the Great Plains area.

Three series of graphs (figs. 4, 5, and 6) are also presented. Figure 

 4, prepared from a part of the data in Table XVII, shows in graphic 

 form the average yields of grain in bushels per acre at each station for 

 each of the five methods studied that have been under trial at all of 

 the stations. The Judith Basin Field Station is not shown in this 

 figure for the reason that grain was neither produced nor expected at 

 that station in this work. Garden City is also omitted because the 

 grain there produced was insufficient to warrant husking. 



Figure 5 is a graphic presentation of the yields of stover as shown 

 in Table XVIII. Like figure 4, it includes only the five methods that 

 have been under trial at all stations.
