116 EXPERIMENTAL FARMS 



2-3 EDWARD VII., A. 1903 

 Twelve Best Yielding Potatoes — Average of Three to Eight Years' Tests. 



An average crop of 414 bushels 43 lbs. per acre. 



The above table was taken from Bulletin 41, prepared by Dr. "Wm, Saunders. 



Potatoes Planted at Different Dates. 



In 1898, an experiment was begun in planting potatoes at different dates, begin- 

 ning when the main crop was put in and continuing at intervals of two weeks un»til 

 August 23, 1898, ^uly 23, 1899; July 21, 1900; July 11, 1901, and July 24, 1902. 

 An earlv and a late variety were used each year, the varieties being Early Norther and 

 Irish Daisy, in 1898, Early Norther and Rural Blush, in 1899 ; Early Norther and 

 Sir Walter Raleigh, in 1900; Early St. George and Rural No. 2, in 1901, and Everett 

 and Carman No. 1, in 1902. In 1902, two plantings w^ere made before the main crop 

 was put in, the yields from the planting made on May 15, being the best of the series. 

 This experiment proves that as far north as Ottawa a fairly good crop of marketable 

 potatoes can be obtained by planting as late as July 10, when they might succeed an 

 early crop, such as garden pease. The vines in this test were not sprayed with Bordeaux 

 mixture this year.
