RESULTS WITH MANGELS 



found in the next table, which shows the average produce of 

 mangels in three fine seasons, 1876, 1890 and 1894. 



TABLE XXXVI. 



AVERAGE PRODUCE OF MANGELS VARIOUSLY MANURED AT 

 ROTHAMSTED, IN THREE FlNE SEASONS, 1876, iS^O, 1894. 



These figures are very striking. We have exactly the same 

 teaching as in the average results during seventeen years 

 already given, but every point is brought out with added clear- 

 ness. The return given by the ammonia salts when employed 

 to the best advantage is now nearly 4 tons of roots per cwt. of 

 sulphate of ammonia. It is clear that in a fine climate a 

 specially good return from the manure used may be expected. 



2. Bath and West of England Experiments. It is 

 not usually advisable to found any conclusion as to the 

 economic value of a manure upon results obtained in a single 

 season ; the influence of weather upon the growth of a crop is 

 so great that success or failure may be largely determined by 

 this circumstance only. In the case, however, of the experi- 

 ments on mangels carried out by the Bath and West of Eng- 

 land Society in 1890, (Journal 1891, 163), we have results 

 obtained in a fair season by the use of identical manures on 

 23 different farms, occupying various soils and districts ; the 

 average result of the manures thus employed is consequently 

 of great practical interest.
