The Wohurn Field Experiments, 1911. 403 



While the results of sugar-beet growing in ly 11 were, of 

 course, exceptional owing to the season, it may at the same 

 time be mentioned that the sugar-beet crop of 1910, grown in 

 rows 21 in. apart, only amounted to 12 ton 2 cwt. of unwashed 

 roots per acre, the mangold crop being 31^ tons per acre, or 

 more than double. 



It is intended to continue the experiment in 1912. 



Experiment on the Use of Lime in Rotation {Butt 

 Furlong), 1911. 



Following the wheat of 1910 came the swede crop. The 

 swedes Avere drilled July 11-14, and singled August 27. 

 The land, however, became so hard and dry that the crop of 

 swedes was an extremely poor one, and, in fact, a failure. 



Experiments on the Prevention of Potato Disease 

 {Lansome Field), 1911. 



A very exhaustive series of experiments on the above 

 subject had l)een mapped out by Mr. Spencer Pickering, of the 

 Ridgmont Fruit Farm, and land for earring these out had been 

 placed at Mr. Pickering's disposal. To these plots were added 

 others on which it was intended to carry out supplementary 

 inquiries, such as the use of dry-spraying, &c. 



The land was well manured with London dung, and the 

 potatoes were duly planted. As it turned out, however, there 

 was no sign whatever of potato disease throughout the year, 

 and the whole experiment, on which so much time and trouble 

 had been expended, accordingly led to no result. 



Grass Experiments {Broad Mead), 1911. 



(a) Manurial experiments. 



{h) On the use of diflEerent kinds of lime. 



In 1911 Broad Mead Field was grazed, and, accordingly, 

 there are no weights of hay to record. 



Further, in consequence of the extreme drought, pastures, 

 after June, were thoroughly burnt up, and presented a parched 

 appearance. It is worthy of note, however, that in experi- 

 ment (a), plot 5 — on which lime had been applied — remained 

 more or less green throughout the whole of the drought, thus 

 presenting a marked difference to any of the others. 



As regards experiment {h) — with different kinds of lime — 

 it is still too early to record any definite result ; ])ut, so far as 

 any conclusions can l)e drawn, it would appear that the Buxton 

 lime and the chalk lime have tlone the best, and that then 

 follow the lias and oolite limes, the magnesian lime l)eing 

 distinctly inferior to any other.
