BAELEY IN THE GREAT PLAINS AEEA. 



17 



The next highest average yield, 20 bushels per acre, was by summer 

 tillage. The average from spring-plowed oat land was 19.7 bushels 

 per acre. The advantage of either fall or spring plowing barley stub- 

 ble varied within narrow limits, but in the average of the series of years 

 no choice is to be made between the two. This indication that the 

 time of plowing is not an important factor allows greater latitude 

 in planning the work of the farm. The plan should be to get the 

 work done early and thus avoid as far as possible the augmentation of 

 work at seeding time. This is of especial importance in the northern 

 portion of the Great Plains, where the seeding season is necessarily 

 short. 



The only method under trial that did not produce barley at a profit 

 is summer tillage. This shows an average loss of $3.20 per acre. The 

 greatest profit, $4.94, was realized from disked corn ground. Fall 

 and spring plowing both show small profits.
