At this centre the yield varied with the variety, and the 

 application or otherwise of potash, between 15*6 tons and 25*1 

 tons per acre. 



As a result of experiments conducted in Suffolk in 1906 the 

 cost per acre at two centres is given as £8 4s. 8d. and 

 £10 js. 6d. In the former case the yield amounted to 14 

 tons per acre, containing 19/4 per cent, of sugar in the roots, 

 and in the second case the yield was 18 tons per acre, con- 

 taining i9'65 per cent, of sugar.
