BARLEY IN THE GREAT PLAINS AREA. 
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.
