Fertilizers Applied to Timothy on Corn Crop. 



189 



The average increase in yield of hay clue to the application of fertil- 

 izers for the seasons 1905-06-07 was in every case worth more than the 

 cost of the fertilizer applied. Hence, any increase in the yield of a suc- 

 ceeding crop as the result of the application of the fertilizers would be 

 classed as clear gain. 



FINANCIAL GAIN 



The net gain of both earn corn and stover due to the previous applica- 

 tion of fertilizers, stated in terms of money, may be seen by examining 

 Table VII. In making these calculations the ear corn was valued at 

 58.9 cents per bushel (70 lbs.), which was the average December price 

 in New York State for corn during the ten years from 1897 to 1907. 

 The stover was valued at $3.00 per ton, which is the standard price in 

 this locality. 



It will be seen that the net gain due to the application of the fertil- 

 izers varies from $2.36 per acre when the single application of acid 

 phosphate was given to plat 712, to $23.95 per acre, when barnyard 

 manure was applied at the rate of 20 tons per acre, plat J^i^. The 

 largest gain due to the use of an artificial fertilizer was that of 

 $20.09 from plat 725, which received the three fertilizing materials 

 in the proportion of 320 pounds acid phosphate, 80 pounds muriate of 

 potash and 320 pounds nitrate of soda per acre. Plat yzj received the 

 same combination of fertilizers and produced an increase of $i5-90 per 

 acre, the two plats averaging $18.00 increase, which was still higher than 

 that produced by any other form of commercial fertilizer. The results 

 of experiments with the same fertilizers on timothy may be found in 

 Bulletin 261 of this station.
