The dry weather in early June, 1922, so injured the fall- -plowed plats 
that they were not able to recover after rains came, and the yields 
of these plats consequently were low. 
TaBLeE 18.—Yveld of barley in two fields at the Northern Great Plains Field Station 
following different cultural treatments and various crops for the 8-year period, 
1915-1922, inclusive.

CORN 
Corn is one of the most important crops that can be grown suc- 
cessfully in this part of the northern Great Plains. It has a double 
importance, because of its value for grain and fodder and because 
corn ground affords one of the best preparations in this area for all 
small-grain crops. The acreage planted to corn has been increasing 
steadily during the past five years. During the years that corn has 
been grown at the station it has produced more pounds of grain per 
acre than any of the small grains. — It is the one crop that has not 
been a complete failure following some particular cultural treatment 
during the driest years. Corn came nearest to a failure in 1920, 
but even then it produced more pounds of grain per acre than wheat 
and oats combined. 
Corn is grown on the lighter soil in the main field on 50 plats in 
combination with small grain, cora, and summer fallow. In the 
south field it 1s grown after corn on eight plats and after summer 
fallow on two plats. 
The variety grown on all plats in the rotations is Northw estern 
Dent. A good strain of this variety was obtained as foundation 
stock in 1914, and seed has been selected from it each year. A very 
early strain has been developed. Seed corn usually is selected during 
the latter part of August and has been picked as early as August 15. 
The selected seed is t ‘horoughly dried in the fall before it is stored for 
the winter.
