POTATOES. 



TEST OF VARIETIES. 



The ground on wliich the different varieties of potatoes were planted was in pota- 

 toes in 1913 and corn in 1914, having been manured for the corn at the rate of 15 tons 

 stable manure per acre. The land was ploughed. in the fall after the corn was cut, 

 and it was again ploughed this spring. It was fertilized with 600 pounds acid phos- 

 phate, 200 pounds aiitrate of soda and 100 pounds of muriate of potash per acre. 



The planting was done May 20 and the crop was dug September 24. The seed was 

 planted in rows 33 inches apart and one foot apart in the rows. The plants were' 

 cultivated five times, and poisoned Bordeaux mixture was used three times. The 

 poisoned Bordeaux used was made up of 4 pounds bluestone and 4 pounds lime to 40 

 gallons water, to which was added one-half pound Paris green and li pounds arsenate 

 of lead to 40 gallons. 



The plants on the majority of the plots seemed to lack in vigour. The disease 

 rhizoctonia noticeably weakened many of the plants and in some cases as a result the 

 plants died prematurely. There was no loss from late blight. The season on the whole 

 was not entirely favourable for potatoes and the crop in general was light. The 

 results obtained are given in the following table: —
