56 POTATOES. 



the picture. The potatoes produced by the three rows of 

 Plot No. 3 weighed 55.8 pounds, and the plants and the 

 potatoes are shown on the right-hand side. The increased 

 yield due to the use of kainit and acid phosphate was 

 reckoned to be at the rate of 16134 bushels per acre. 



Referring to Bulletin No. 61 of the Kentucky Experi- 

 ment Station, dated March 1896, we find some very inter- 

 esting experiments conducted upon potatoes, which the 

 following illustration sets forth :

The season was an unfavorable one for potatoes, but 

 all the results obtained plainly reveal the importance of 

 potash for this crop. The two plots on the left side of 

 the illustration, Plots Nos. 5 and 6, received no potash, 

 Plot No, 5 being unfertilized and Plot No. 6 receiving 

 nitrogen and phosphoric acid without potash. The two 

 plots appearing on the right side of the picture were 

 fertilized with potash, Plot No. 4 receiving muriate of
