RESULTS WITH TURNIPS 



phosphates without dung, while on four plots 86 ibs. of sulphate 

 of ammonia per acre were applied at various dates. The ex- 

 periment was repeated in 1892 upon 42 farms with some vari- 

 ation as to the times of application. The results of these ex- 

 periments were as follows :

The two seasons w r ere very different. In 1891 there was 

 a prolonged drought in June and July, followed by very wet 

 weather. The season of 1892 is described as somewhat dry, 

 cold and backward. It will be seen that in both seasons the 

 advantage lies with the earliest application of the ammonia 

 salts.
