432 EXPERIMENT STATION RECORD. 



The yields and composition of the crop are given in tabular form. 

 The author summarizes the results as follows: 



"The use of 1,000 lbs. of fertilizer per acre gave the greatest profit. The slightly 

 larger yield caused by increasing this application to 1,500 or 2,000 lbs. cost in fer- 

 tilizer expense considerably more than the market value of the potatoes. 



"The fertilizer cost of the increased yield of potatoes where 500 or 1,000 lbs. of 

 fertilizer was used per aire was 20 cts. per bushel in those experiments that pro- 

 ceeded without unfortunate conditions. 



"The yield of tubers from the Long Island formula was somewhat larger than 

 from a formula compounded with reference to the composition of the potato plant. 



"The evidence obtained in these experiments concerning the relative effect of the 

 muriate and the sulphate of potash upon the composition of the potato tuber is 

 inconclusive. 



" The proportions of the valuable plant-food compounds found in the potato tubers 

 were not influenced appreciably by the amount or kind of fertilizer used."
