Suggestions. — Additional applications of nitrate of soda at the 

 rate of 50 pounds an acre may be made as a top-dressing twice 

 after the crop is well started, at intervals of three weeks. 



Fresh stable manure is to be avoided on account of weed seeds, 

 and also a tendency to favor the growth of onion maggots. Stable 

 manure is preferably used in soil two years before planting onions. 

 An excess of nitrogen delays the ripening and injures the keeping 

 qualities of onions.
