Fertilisers for Market Garden Crops.

dung did not do much better than the lightly dunged plot, and 

 not nearly so well as the plots on which dung and chemical 

 fertilisers were combined. 



Probably the best dressing for this crop is a light quantity of 

 dung, 6 cwt. of superphosphate, at least 1 cwt. of sulphate of 

 potash (or 4 cwt. of kainit), and from 2 cwt. to 4 cwt. of nitrate 

 of soda per acre. 



We find that the mode of manuring very greatly affects the 

 value of this crop, not so much on account of the influence of 

 the manure on the total number of heads grown as on account 

 of its influence on the earliness of the crop. There is very little 

 demand for globe artichokes after the close of the London 

 season. Heads grown in the early part of the season are readily 

 marketable, while those grown after about July are not worth 

 the expense of sending to market. Such, at all events, is the 

 experience of those who cater for London. 



Jerusalem Artichokes. 



On the whole, our experience with this crop indicates, as in 

 the case of winter lettuces, that if a grower has been so extra- 

 vagant as to use as much as 50 loads of town dung per acre for 

 the preceding crop, Jerusalem artichokes may most profitably 

 follow that crop without any additional manuring ; but if only a 

 moderate dressing of dung has been applied to the preceding 

 crop, they may be most satisfactorily planted without any 

 additional dung, but with a dressing of superphosphate and 1 cwt. 

 of sulphate of potash per acre, and top-dressed with 2 cwt. of 

 nitrate of soda per acre. 



Carrots and Parsnips, 



Carrots and parsnips are usually grown on the residue of dung 

 applied for a previous crop. The following table gives extracts 

 from our records relating to these crops. 



Here, again, if the grower has used on any of his fields as much 

 as 25 tons of town dung per acre for a previous crop, it will 

 probably pay him better to plant his carrots or parsnips in such 

 a field than to manure them specially. But presuming that he 

 has manured the previous crop with a moderate quantity only 

 of dung, then he had better plant his carrots or parsnips after
