It will be seen that, on the average, potash has produced little or no 

 effect when applied in addition to dung, although on the plots on which 

 dung was not used (recorded in previous reports but not shown in the 

 above table) there was an average increase of 2 tons per acre due to 

 potash. In the later years, however, potash has told even on the dunged 

 plots. 



On the whole, it will be seen that great economy has been shown in 

 avoiding a large quantity of dung, using in its place a small quantity of 

 dung with phosphates and 4 cwt. of nitrate of soda per acre.

Although the crop was so good a one where dung and chemical ferti- 

 lisers were used together, the undunged plot did badly, owing to the young 

 plant having languished for want of moisture in its earlier stages ; and in 

 this case potash salts failed to produce the substantial increase which it 

 had shown in the case of the undunged plots in previous years. 



We would suggest, as a good general dressing for this crop, 25 loads 

 (i.e. 12^ tons) of dung, 4 to 6 cwt. of superphosphate, and 4 cwt. of nitrate 

 of soda per acre, 2 cwt. of nitrate per acre being applied either at sowing 

 time or after the plant is up, according to the general dryness of the climate, 

 and a further quantity of 2 cwt. per acre given as a top dressing a month or 

 so afterwards. If dung is scarce, the crop should be grown on land which 

 has been dunged for the previous crop, and should, in addition to super- 

 phosphate and nitrate of soda, receive 4 cwt. of kainit or 1 cwt. of sulphate 

 of potash per acre, well mixed with the soil during the preparation of the 

 seed bed or earlier. In this case, after applying nitrate of soda as above 

 recommended, an additional top dressing may be given, bringing the total 

 quantity of nitrate of soda up to, say, G cwt. per acre. 



Rhubarb. 



Our first plantation was made in 1895, four varieties being selected, 

 namely, three of small Rhubarb and one of large or coarse. The small 

 varieties were 1 Albert,' ' Paragon,' and ' Johnson's St. Martin ' ; the large
