1924. 



The experiment of 1924 was in Stackyard Field, following 

 oats. " Plumage Archer," as before, was drilled — 3' bushels 

 per acre — on March 11th, the various manures being applied at 

 the same time. The barley grew well. The plot to ripen quickest 

 was plot 2 (complete manuring), and the phosphate plot (3) ripened 

 more quickly than the potash one (2). 



The barley was cut on August 12th. 



The yields generally were lower than in 1923 and the relative 

 yields of the no-phosphate and no-potash plots are reversed in the 

 two years. The results for the two years are given in the follow- 

 ing table : — 



6. Experiments with Sulphate and Muriate of Ammonia. 



Comparisons of these two manures were carried out in 1923 

 on wheat and barley and in 1924 on wheat, mangolds and swedes. 

 The details of cultivation, etc., follow. In each experiment 1 cwt. 

 of sulphate of ammonia and the equivalent quantity of muriate 

 were employed : — 



Wheat, 1923 : Road Piece, thin light sandy loam. Drilled, 

 2£ bushels per acre, October 23rd, 1922. Top 

 dressings applied May 31st. Cut August 10th, 

 the previous crop being " seeds," ploughed in. 

 No basal manuring was given. 



Barley, 1923: Butt Close, light sandy loam. Drilled, 2} 

 bushels per acre, April 10th. Top dressing ap- 

 plied June 2nd. Cut August 30th. Previous 

 crop, swedes fed off with sheep. 



Wheat, 1924: Great Hill, light sandy loam. Drilled, 3 

 bushels per acre, November lst-2nd, 1923. Top 

 dressing applied June 3rd. Cut August 15th- 

 18th. Previous crop, red clover (cut twice). 



Mangolds, 1924 : Warren Field, Oxford clay. Dung, 8 tons 

 per acre, April 26th. Super, 2 cwt. and Kainit 

 3 cwt. per acre, May 13th, seed drilled 6 lb. 

 per acre, May 15th. Top dressings applied 

 Tulv 22nd-23rd. Roots pulled November 15th-
