POTATOES, $3 



potash alone and Plot No. 9 receiving the same applica- 

 tion as Plot No. 6, but with potash added. The results 

 are very striking. The average yield from the unfertilized 

 plots was 42.9 bushels. Potash alone produced 87 bushels s 

 which is an increase of more than 100 per cent. Plot 

 No. 9 produced nearly 127 bushels against 59 bushels 

 from Plot No. 6, where phosphoric acid and nitrogen were 

 used without potash, being an increase of 115 per cent 

 produced by the use of muriate of potash. 



One more result may be given, showing the favorable 

 influence on potatoes, of a fertilizer containing potash. 

 Recent experiments (by Mr. T. J. Stroud) at Shaker Sta- 

 tion, Connecticut, confirm the conclusions reached inde- 

 pendently at the West Virginia and Kentucky Experi- 

 ment Stations. For the purpose of comparison, the yield 

 of potatoes from plots numbered i, 2 and 4, all of the 

 same size, are shown on the preceding page. 



No. i shows the yield of potatoes from a plot which 

 received no fertilizer. The product was at the rate of 73 

 bushels per acre. About one-half of the potatoes, as you 

 will see, are small in size. 



No. 2 shows the yield of potatoes from a plot which 

 was fertilized with acid phosphate and nitrate of soda. 

 Here, the yield was at the rate of 140 bushels per acre. 

 About one-fourth of the potatoes from this plot were 

 undersized. 



No. 4 shows the yield of potatoes from a plot which 

 received the igme fertilizer an No. a, but with 140 poundi
