Figure 5 presents the average yields of fodder at each of the stations. 

 The results by each of the five methods that have been under trial at 

 all stations are shown separately. 



It appears that the yields reported from the Judith Basin Field 

 Station and from WiUiston are abnormally high. While the yields 

 have generally been good at these stations, it is doubtful if they have 

 been as much higher than those at some of the other stations, as these 

 figures indicate. It is probable that in the years showing excessively 

 high yields the crop 

 has not been well 

 dried at the time of 

 weighing. 



A very striking fact 

 brought out by this 

 graphic showing is the 

 uniformity in the 

 amount of stover or 

 fodder produced by all 

 methods at the sta- 

 tions in Montana and 

 North Dakota. So 

 far as the production 

 of rough feed is con- 

 cerned, there appears 

 very little difference 

 on which to base a 

 choice. South of 

 North Dakota there 

 is a general agree- 

 ment of heavier 

 yields of stover or 

 fodder after corn than 

 after small grain, ex- 

 cept that at Scotts- 

 bluff the yields are 

 heavier after small 

 grain than after corn. 



Small differences in stover yields are to be noted between the results 

 following spring and fall plowing. On the whole, the average yields 

 by the two methods are almost the same. 



The most noticeable effect resulting from cultural practice is the 

 very marked increase in the yield of stover resulting from growing 

 corn on summer-tilled land at the more southern stations — Garden 

 City, Dalhart, and.Amarillo. Only small increases in yields have 

 attended the use of this method at Scottsbluff, North Platte, and Hays.

Fig. 5. — Graphs showing the average yields of corn stover in pounds 

 per acre by different methods at thirteen field stations in the 

 Great Plains area. The methods of tillage are indicated by Arabic 

 numerals at the top, as follows: 1, Fall plowing after corn; 2, fall 

 plowing after small grain; 3, spring plowing after corn; 4, spring 

 plowing after small grain; 5, summer tillage.
