CORN IN THE GREAT PLAINS AREA. 
25 
No grain in sufficient quantity to husk was produced in any year 
by any of the methods under trial. The only material difference 
to be noted in the yields by different methods is the increased yield 
attending the growth of corn on land which was summer tilled the 
previous season. The method of summer tillage gave an average 
yield of 4,700 pounds of fodder per acre for the three years that 
weights were obtained. The crop produces a good amount of feed, 
but with the valuation and costs as here assigned it has been grown 
at small losses, ranging from 34 cents per acre by listing after corn to 
$2.96 on summer-tilled land. 
DALHART FIELD STATION. 
Table XVI presents data obtained in the growth of corn by dif- 
ferent methods at Dalhart, Tex. The results of the work of six years 
are given. In three of the six years grain was produced by all 
methods.

The two heaviest yielding methods were summer tillage and 
listing after corn. Between the grain yields by these two methods 
there is little difference, but in the yield of fodder the summer tillage 
shows a marked superiority. Between the other methods little 
choice is to be made, although corn appears to yield slightly heavier 
after corn than after small grains and slightly heavier by spring 
plowing than by fall plowing. The crop was produced at a profit 
by all methods under trial. The net profits realized range from 25 
cents per acre by spring plowing after small grain to $2.14 by sjmng 
plowing after corn and $4.80 by listing after corn.
