RELATIVE FARM VALUE OF CROPS.

DISKING CORN STUBBLE GIVES BETTER RESULTS THAN PLOWING FOR 

 SPRING WHEAT WHICH IS TO FOLLOW. 



In Table XXV a comparison has been made between the average 

 farm values of rotations Nos. 1 and 3. These two rotations are 

 identical, except that in No. 1 the corn stubble was disked and in No. 3 

 it was fall plowed. In eleven tests, the disking, and in seven tests, 

 the plowing, gave best results. The average was 36 cents per acre 

 in favor of disking. In none of the tests was the gain in favor of 

 plowing sufficient to more than pay for the extra labor, and in four 

 it was insignificant. On the other hand, the gain from disking was, 

 in five tests, enough, together with the less cost of disking, to make the 

 disking decidedly the better practice. It may therefore be con- 

 sidered that these investigations indicate that disking is the better 

 practice at all the stations.
