EXPERIMEyTAL FARMS 



9-10 EDWARD VII., A. 1910 



BAELEY PLOTS. 



The quantity of seed sown per acre on the barley plots was about 2 bushels from 

 1889 to 1891, IJ bushels in 1892 and 1893, and 2 bushels from 1894 to 1908, inclusive. 

 Two-rowed barley was used for seed throughout until 1902, when Mensury, a six- 

 rowed sort, was tried. The varieties used were as follows: 1889 to 1891, Saale; 1892, 

 Goldthorpe; 1893, Duckbill; and in 1894 to 1901, Canadian Thorpe, a selected form 

 of the Duckbill. Since 1902, Mensury has been sown. In 1908 it was sown May 16, 

 and was harvested on August 10.

Fertilizers applied eacli year from 1889 to 

 1898 or 1899. No fertilizers used from 

 that time to 1905. Clover sown in 1899 

 and each year 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.

 Variety, 

 Mensury. 



Barn-yard manure, well rotted, 15 tons per 

 acre each year to 1898, inclusive. No 

 manure used from 1899 to 1905. In 1905- 

 6-7-8, 15 tons per acre again used 



Burn-yard manure, fresh, 15 tons per acre 

 each year to 1898, inclusive. No manure 

 used from 1899 to 1905. In 1905-6-7-8, 15 

 tons per acre again used 



Unmanured from the beginning 



Mineral phosphate, untreated, finely ground 

 500 lbs. per acre, used each year from 1888 

 to 1897, inclusive. In 1898 and 1899 a 

 similar weight of the Thomas' phosphate 

 was used. No fertilizer used fi-om 1900 

 to 1905. In 1905-6-7-8 fertilizer 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, inclu- 

 sive. 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 

 fertilizers again used as in 1899 



Barn-yard manure, partly rotted and ac- 

 tively fermenting, 6 tons i)er acre, min- 

 eral phosphate, imtreated, 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 1897, inclusive. In 1S08, 

 500 lbs. of the Thomas' phosphate were 

 used in place of the mineral phosjihate. 

 No fertilizers used from 1900 to 1905. In 

 1905-6-7-8 fertilizers again used as in 1898. 



Mineral phosphate, imtreated, finely ground 

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

 ashe.s, unleached, 1,000 lbs. per acre, used 

 each year from 1888 to 1897, inclusive. 

 In 1898 and 1899, 500 lbs. of the Thon.as' 

 phosphate was used in place of the min- 

 eral phosphate. No fertilizers used from 

 1900 to 1905. In 1905-6-7-8 fertilizers 

 used as in 1899 , . . . .
