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.

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 spring 

 plowing after corn and $4.80 by listing after corn.
