BARLEY IN THE GREAT PLAINS AREA. 25 
The results range from an averago yield of 8.9 bushels per acre 
on spring-plowed barley land to 19.3 bushels per acre on summer- 
tilled land. Green manure is in second place, with average yields 
of 15.5 bushels per acre. In all but the first year, peas plowed 
under produced slightly larger crops than winter rye similarly 
treated. There has been a gain of 1 bushel per acre from sub- 
soiling over fall plowing not subsoiled. Furrowing over winter 
with a lister produced practically the same as fall plowing. Fall- 
plowed barley stubble gave better results than spring-plowed bar- 
ley stubble. Spring-plowed oat stubble produced practically the 
same as fall-plowed barley stubble. Disked corn ground produced 
slightly better yields than the average of the crops following small 
grains on fall or spring plowing. 
The main positive result shown in the table of yields is an increase 
of about 6 bushels an acre as the result of summer tillage, or a some- 
what lesser increase as a result of modifying the summer tillage by 
plowing under a crop of green manure. 
The only method that produced barley at a profit was that of 
disking corn ground. This shows a profit of $1.13 per acre. All 
other methods show losses which range from 24 cents on listed 
ground to $3.49 on summer-tilled land and $8.15 on green-manured 
land. 
GARDEN CITY FIELD STATION. 
During the work of six years with barley under study at Garden City, 
Kans., one crop has been lost by drought and one by hail. In the 
other four years, yields have been obtained. 
The highest average yield, 11 bushels per acre, has been obtained 
from summer tillage. Next to this in point of average yield is disked 
corn ground. Subsoiling has given the same average yields as fall 
plowing done at the same time without subsoiling. Marked advan- 
tage in two years appears to have been derived from furrowing with 
a lister and leaving the land rough through the winter instead of 
plowing. 
On the whole the average yields are so low and there are so many 
inconsistencies in the behavior of the different methods from year to 
year that the results are chiefly valuable as indicators rather than as 
definite guides to practice. It appears that there is sound reason for 
the consensus of opinion as evidenced by farm practice which gives 
little place to spring-sown barley in the territory served by this 
station. 
The crop has been produced at a loss by all the methods under 
trial. The losses range from $1 per acre on disked corn ground to 
$6.89 on summer-tilled land.
