In 1903 corn planted in hills gave but a slightly larger yield than corn planted in 

 drills. In the average of -4 years the results show a difference of 1 ton of total crop 

 and one-fifth of a ton of husked ears per acre in favor of planting in hills. The 

 results with fertilizers are summarized in the following table:

The complete fertilizer application was composed of one-third of the quantity of 

 nitrate of soda, muriate of potash, and superphosphate applied alone. The largest 

 increase of Swedish turnips as compared with the unfertilized land was obtained 

 with the complete fertilizer at a cost of 1.7 cts. per bu., of mangels with nitrate of 

 soda at 2.3 cts. per bu., of oats with complete fertilizer application at 47 cts. per bu., 

 and of fodder corn with muriate of potash $2.87 per ton.
