BULLETIN 218, XT. S. DEPARTMENT OF AGRICULTURE. 
GENERAL DISCUSSION OF RESULTS. 
In the preceding pages data have been presented and briefly dis- 
cussed separately for each station without reference to results at 
other stations. In the following pages the data are considered 
from a more general standpoint. Table XIX will assist in this study. 
In this table the average yields at the several stations are grouped 
under different methods of preparation. The figures here given are 
taken from the tables showing details for each station. 
Data in regard to yields and cost of production are also assembled 
in such a way as to show the profit or loss in dollars and cents per 
acre for the average crop for each method for which it has been 
computed at each station.

oats by different methods at fourteen stations in the Great Plains area.

The averages of columns 
and 9 only are comparable. 
On the whole, seasonal conditions have produced much wider 
variations in yields than have been produced by differences in cul- 
tivation. Some seasons are so favorable that any and all methods 
give good returns at stations where oats can be successfully grown.
