22 HATCH EXPERIMENT STATION. [Jan. 



planted by hand in rows three and one-half feet apart and 

 at a distance of twelve inches in the row. Planting has 

 always been early. 



Oulture and Appearance while growing. 



The land has been harrowed once before the seed was up, 

 and later the harrow or Breed's weeder has been used once 

 or twice more. The work thereafter has been carefully and 

 seasonably performed with one-horse cultivators and hand 

 hoes. During the early part of each of the four seasons the 

 crop growing where the sulphate of potash had been applied 

 was distinctly more vigorous and of a deeper color than that 

 growing on the muriate. This difference was maintained 

 throughout the season, but became less noticeable towards 

 the close of the season of growth. 



A similar difference in favor of drill application was always 

 observed, also somewhat less marked towards the close of 

 the season. 



The crops of 1892 and 1893 were not affected by leaf 

 blight to any great extent ; but those of both 1894 and 1895 

 were affected, and as a consequence th^ tubers were less per- 

 fectly matured in those years.
