BULLETIN 222, U. S. DEPARTMENT OF AGRICULTURE. 
In the year of heavy yields and in the following year of very light 
yields the best production was on disked corn ground. In 1912 the 
only yield secured was from spring-plowed barley stubble. The same 
plat also gave the highest yield in 1913. It is probable that in both 
cases these results were due to the fact that the crop on this plat 
made a poor start and had a thinner stand, which helped it in with- 
standing the drought of the summer. 
Subsoiling, as compared with fall-plowing done at the same time, 
appears to have been effective in increasing the crop in the year of 
good yield, but not in overcoming drought in other years. The same 
observation applies to furrowing with the lister instead of plowing. 
In the average results from the whole period of years, summer tillage 
and disking corn ground stand by themselves. On the basis of yield 
there is little or no choice to be made between the two. But when the 
cost of production is figured in connection with the value of the crop 
it is seen that by all methods except the use of disked corn ground the 
crop has been produced at a loss. The low cost of production by the 
disking method enables it to show a nominal average profit of 35 
cents per acre. 
SCOTTSBLUFF FIELD STATION. 
The results of only two years with barley are available for study 
from Scottsbluff, .Nebr. The crop of 1913 was lost through a fault 
in the seed that made it necessary to reseed. The reseeded crop 
grew and maintained the continuity of the work in the effect upon 
the ground for the following crop, but was too late to mature before 
growth was checked by the hot weather of midsummer. Production 
in one year was good and in the other it was poor.

The crop of 1913 was a failure, due to poor seed.
