by that of barley. The general experience at Akron indicates that 
corn produces better on sandy land than on the heavier soil at the 
station. 
The highest average yield was 35.6 bushels, in 1920. There was 
no complete failure, but many methods failed to produce grain in 
1911, 1913, and 1916, years of drought. 
The highest average yield under any method was 23.1 bushels per 
acre, on summer fallow. The higher average from this preparation 
is due not so much to increased yields in the better years as to in- 
creases in the years of medium yields and in the poorer years when 
other methods were nearly or quite overcome by drought. No 
complete failure has been recorded on summer-fallowed land, the 
lowest yield on this preparation being 8.4 bushels, in 1919. 
The next three highest average yields were produced by continuous 
cropping to corn. Under this system the 15-year average yield was 
17.9 Dushels on fall plowing, 17.6 bushels on spring plowing, and 16.2 
bushels on subsoiling. These results show the feasibility of raising 
corn continuously on the same land if this is required by the type or

system of farming practiced, but that if small grain is to be grown 
also labor will be conserved and greater relative returns realized if 
the corn and small grains are rotated. 
Two other plats were cropped continuously to corn. One was 
listed in the fall and planted with a lister, splitting the ridges. The 
other was planted with a lister without previous cultivation. The 
one listed in the fall averaged 15.6 bushels, and that listed in the 
spring averaged 13.9 bushels. At the station corn does not start as 
quickly and vigorously when listed as when surface-planted, and 
difficulty is sometimes experienced in getting a stand. This happens 
especially when heavy rains flood the furrows. When this occurs 
the surface becomes crusted on drying and the seed may rot or the 
seedlings be unable to emerge, or, if further advanced, the seedlings 
may be covered by soil washed into the furrows. On the other hand, 
listed corn frequently withstands drought somewhat longer or better 
than that surface-planted. General experience in this region is that 
listing is of relatively greater value on the lighter and warmer soils 
than on the heavier land.
