EXPERIMENTAL FARMS 



1-2 EDWARD VII., A. 1902 



between the best and poorest being 356 bushels 24 lbs. per acre, showing the great im- 

 portance of planting the most productive varieties. The average yield per acre from 

 all the varieties tested was 365 bushels 25 lbs., being 247 bushels 25 lbs. greater than 

 the average for the province of Ontario for 1901, which was 118 bushels. This dif- 

 ference is greater, however, than it would be if the varieties had been grown by the 

 acre instead of in small plots. 



The potatoes were planted this year in the same sandy loam soil they occupied in 

 1900, as in the orchard inclosure this was the best place available for them. On April 

 22 and 23, however, the land was given a good dressing of well rotted manure, which 

 was ploughed under on April 25. Just before planting time it was thoroughly incor- 

 porated with the soil by harrowing, twice with the disc harrow and once with the 

 smoothing harrow. Drills were made 2\ feet apart and about 4 inches deep. The 

 sets were of fairly uniform size and had at least three eyes with a good amount of 

 flesh and were planted 1 foot apart. Each variety occupied one row 66 feet long. The 

 sets were covered with the hand hoe to get as nearly uniform conditions as possible. 

 The soil was harrowed once before the potatoes came up, to kill any weeds which had 

 germinated, to level the ground, and to loosen the surface of it. The soil between the 

 rows was kept cultivated until the vines met, but the latter were not hilled up. The 

 vines were sprayed with Paris green to destroy the potato beetle, and 4 times with 

 Bordeaux mixture to prevent blight and rot. The potatoes were planted on May 28 

 and dug on October 4.
