EXPERIMENTAL FARMS 



7-8 EDWARD VII., A. 1908 



WHEAT PLOTS. 



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

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

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

 In 1S94, Eio Grande was used, and from 1895 to 1906, inclusive. Red Eife. In 1906 

 the Red Fife was sown May 3, ajid was ripe August 17.

Fertilizers applied each year from 1888 to 

 1898 or 18!)!). No fertilizers used from 

 that time to 1!)05. Clover sown in 18!)9 

 and each year after to 1905 with the grain 

 and plouffhed nndf'r in the autumn. In 

 1905-6 fertilizers again applied as in 

 1898- Clover discontinued.

Barn-yard manure (mixed horse and cow

 1888 ; 15 tons per acre each year after to 



1898 inclusive. No manure used from 



1899 to 1905. In 1905-G 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 15 tons per a^re again 

 used 



Unmanured from the beginning 



Mineral phosphate, untreated, finely 

 ground, 500 lbs. per acre, used each year 

 from 1888 to 18!)7 inclusive. In 1898 and, 

 1899 a similar weight of the Thomas' 

 phosphate was used. No fertilizer used 

 from 1900 to 1905. In 1905-6 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 1808 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 ferti 

 lizers again used as in 1899 



Barn-yard manure, partly rotted and ac- 

 tively fermenting, six tons per acre ; 

 mineral phosphate, untreated, finely 

 ground, 500 lbs. per acre, composted 

 together, intimately mixed and allowed 

 to heat for several days before using, 

 applied each year from 1888 to 18!)7 

 inclusive. In 1898, 500 lbs. of Thomas 

 phosphate were used in place of the min 

 eral phosphate. No fertilizers used from 

 1899 to 1905. In 1905-6 fertilizers again 

 used as in 1898 



Mineral phosphate, untreated, finely 

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

 wood ashes,unleach9d, 1,000 lbs. pwr acre, 

 used each year from 1888 to 1897 inclusive. 

 In 1898 and 1899, 500 lbs. of the Thomas 

 l)hosphate were used in place of the 

 mineral phosphate. No fertilizers used 

 from 1900 to 1905. In 1905-6 fertilizers 

 again used as in 1899
