[Results of experiments with ensilage hay, barley, oats, and wheat], 

 A. J. Perkins and W. J. Colebatch (Jour. Dcpt. Agr. So. Aiist., IS {IMO), Nos. 

 S, pp. 652-662; D, pp. 736-7 J,5).— A sowing of a mixture of 60 lbs. of' Calcutta 

 oats, 100 lbs. of King Early wheat, 4 lbs. of alfalfa, and 8 lbs. of vetch per acre 

 yielded 9 tons 14 cwt. of green stuff per acre. Recent averages in yield of 

 ensilage from mixed sowings of wheat, oats, and vetch have ranged from 5 to 

 12 tons per acre. Recently-chaffed and unweighted ensilage in a pit 13 ft. by 

 IS ft. 10 in. by 14 ft. deep averaged a little over 31^ lbs. per cubic foot. A mix- 

 ture of oats and w^heat bound in sheaves lost in drying 71.61 per cent of their 

 original growth during 1909. The average of the losses during 4 successive 

 seasons was 69.7 per cent, so that 10 tons of green stuff was reduced to a little 

 over 3 tons of hay. 



In a mannrial test with wheat. 3 times as great a yield was securetl after 

 the application of a mixture of 195 lbs. of superphosphate, 100 cwt. of nitrate 

 of soda, and 1 cwt. of muriate of potash as was secured from the application 

 of the superphosphate alone. The substitution of 1 cwt. of sulphate of potash 

 for the muriate in the same mixture was followed by an increased yield of 2 

 bu. 15 lbs. In a field test, among 26 varieties of wheat averaging 25 bu. 15 lbs. 

 per acre. Federation (selection 1) produced the highest yield, 33 bu. 20 lbs. 

 per acre. On variety plats Mahmoudi durum wheat produced the highest yield, 

 36 jbu. 13 lbs. per acre, while the pedigreed college wheats. King Red (selection 

 4), Late Gluyas (selection 4), and Bearded Gluyas (selection 4), yielded .33 

 bu. 41 lbs., 33 bu. 8 lbs., and 30 bu. 35 lbs. per acre, respectively.
