EXPERIMENTAL FARMS 



9-10 EDWARD VII., A. 1910 



WHEAT PLOTS. 



The seed sown on each of these plots from the beginning has been in the propor- 

 tion of about 1^ bushels per acre, excepting in 1894; and the varieties used were as 

 follows :— In 1888 to 1891, White Eussiaji, and in 1892-3, Campbell's White Chaff. In 

 1894, Rio Grande was used, and from 1895 to 1908, inclusive, Red Fife. In 1908, the 

 Red Fife was sown May 16, and was ripe August 18. 



TABLE I.— EXPERIMENTS WITH FERTILIZERS ON PLOTS OF WHEAT. 





Fertilizers applied each year from 1888 to 

 18'JS or 18;ii). No fertilizers used froin 

 that time to 1905. Clover sown in l.S9it 

 and each j ear after to 1905 with the grain 

 and ploughed under in the autumn. In 

 1905-6-7-8 fertilizers again applied as in 

 1898. Clover discontinued. 



1 



Barn-yard manure (mixed horse- and cow- 

 manure), well rotted, 12 tons per acre in 

 1888 ; 15 tons per acre each year after to 



1898 inclusive. No manure used from 



1899 to 1905. In 1S05-6-7-8, 15 tons per 

 acre again used 



Barn-yard manure (mixed horse- and cow- 

 manure) fresh, 12 tons per acre in 1888 ; 

 15 tons per acre each year after to 1898 

 inclusive. No manure used from 1899 to 

 1905. In 1905-6-7-8, 15 tons per acre again 

 used 



Un manured from the beginning 



Mineral phosphate, untreated, finely 

 ground, 500 lbs. per acre, used each year 

 from 1888 to 1897 inclusive. In 18!'8 and 

 1899 a similar weight of the Thomas' 

 jihosijhate was used. No fertilizer use;i 

 from 1900 to 1905. In 1905-6-7-8 Thomas' 

 phosphate again used as in 1899 



Mineral phosphate, untreated, finely 

 ground, 500 lbs., nitrate of soda, 200 lbs. 

 per acre used each year from 1888 to 1897 

 inclusive. In 1898 and 1899, 500 lbs. of 

 the Thomas' phosphate were used in place 

 of the mineral phosphate. No fertilizers 

 used from 1900 to 1905. In 1905-6-7-8 fer 

 tilizers again used as in 1899 



Barn-yard manure, partly rotted and ac- 



tively fermenting, 



mineral

for several days before using. 



ap lied each year from 1888 to 1897 

 inclusive. In 1898, 500 lbs. of Thomas 

 li'.iO.-;i)hate were use I in jilace ot the min- 

 eral phosphate. No fertilizers used from 

 1899 to 1905. In 1905-6-7-8 fertilizers 



again used as in 1898 



Mineral phosphate, untreated, finely 

 ground, 500 lbs ; nitrate of soda, 200 lbs.; 

 wood ashes, unleached, 1,000 lbs. per acre, 

 used each year from 1888 to 1897 inclusive. 

 In 1898 and 1899, 500 lbs. of the Thomas' 

 phosphate weie used in place of the 

 mineral phosphate. No fertilizers used 

 from 1900 to 1905. In 1905-6-7-8 fertili- 

 zers again used as in 1899
