COST OF PRODUCING WINTER WHEAT IX OREGON"

better to analytical study. These quantity cost factors in the case 
of winter wheat in this region are shown in Figure 9. 
The data have been itemized so that the amounts and cost of any 
one item can be readily compared one year with another. The acre 
cost of most items of expense for both owners and renters (Tables 19 
and 20) declined somewhat over the period 1920 to 1922. On rented 
farms in 1921 the high acre cost for use of tractor was mainly due to 
a greater number of hours of use on winter wheat, whereas the higher 
cost for use of combine in 1921 as compared with 1920 and 1922 was 
mainly due to a greater number of hours of use on winter wheat at 
a higher cost per hour of operating.
