THE MANURING OF MARKET-GARDEN CROPS.

the size of the heads. The Cauliflowers grown with the aid of phosphates 

 and nitrate of soda have been uniformly of decidedly better quality than 

 those grown with dung alone, the midribs of the sheathing leaves being 

 so tender and free from tough vascular tissue as to be soft and readily 

 edible, while those of the heads grown with dung only have been com- 

 paratively tough and fibrous at the base, as is usually the case in the 

 full-grown Cauliflower of the market. 



Summarising our experience thus far, we should for general purposes 

 recommend for Cauliflowers a light dressing of dung (about 12 tons per 

 acre), with from 1 to 6 cwt. of superphosphate, 4 cwt. of kainit (or 1 cwt. 

 of sulphate of potash), and 4 cwt. of nitrate of soda per acre. If the dung 

 supply should run short, then use 6 cwt. of superphosphate and 4 cwt. of 

 kainit, well incorporated with the soil before planting, and sow 4 cwt. of 

 nitrate of soda per acre directly the plants are well established, giving 

 a further top dressing of 2 to 4 cwt. of nitrate per acre a month later. 

 On land deficient in lime, superphosphate may be replaced by basic slag, 

 phosphatic Peruvian guano, or fine bone meal. 



Broccoli. 



We cut our eighth crop of Broccoli (or Winter Cauliflowers) in 1902. 

 This crop is planted out in the summer and cut during the following 

 spring. 



The first five crops were grown on the original plan of manuring and 

 the last three on the newer plan, including larger dressings of nitrate of 

 soda than had been previously used. 



The heads are cut and individually weighed just as the "flower" 

 shows signs of beginning to "break." 



The results obtained are set out in the following tables : —
