BARLEY IN THE GREAT PLAINS AREA. 



23 



AKRON FIELD STATION. 



The results at Akron, Colo., secured by fall plowing barley stubble, 

 furrowing with a lister instead of plowing, spring plowing barley stub- 

 ble, spring plowing oat stubble, and disking corn ground in prepara- 

 tion for barley, have been dependent upon the season. Some seasons 

 have favored one method and other seasons other methods, but on 

 the whole little choice is to be made from the average of the six years 

 under study. Subsoiling as compared with fall plowing without sub- 

 soiling has been done at a distinct loss each year except the first. 



Summer tillage has increased the average yield from 17.6 bushels 

 following a small-grain crop to 24.8 bushels per acre. Subsoiling and 

 summer tillage show small losses of $1.33 and $1.23 per acre. Other 

 methods show profits ranging from $1.17 on fall-plowed land to $2.89 

 on disked corn ground.
