476 Fertilisers for Market Garden Crops. 



We attribute the excellence of the results obtained by heavy 

 dunging in this case mainly to its effects in the direction of 

 conserving moisture. 



With late varieties we have obtained the best results by 

 using light dung combined with chemical fertilisers. 



The early varieties were " Windsor Castle," or " White 

 Beauty," while the main crop varieties were " Beauty of 

 Hebron," " Magnum Bonum," " Imperator " and " Up-to-date." 



It will be seen that potash has produced very little effect in 

 the case of the early potatoes, while its effect has been very 

 marked on the late varieties. 



It is interesting to notice that, although in two seasons we 

 have used, where no dung was applied, as much as 8 cwt. of 

 nitrate of soda per acre, this large quantity of nitrogenous 

 manure produced no prejudicial effect upon the quality of the 

 potatoes ; but, until we have larger experience, we should not 

 advise the use of more than 4 cwt. of nitrate of soda per acre. 



Spring (or Summer) Onions. 



With spring or summer onions our experience is limited, for 

 in several years the plant has practically failed owing to drought 

 or wireworm. In two seasons we grew crops up to 10 or 11 

 tons per acre of marketable onions, and, strangely enough, on 

 the average of these two years, heavy dung gave little advan- 

 tage over light dung, the best results in both years being
