Nitrate of soda applied as a top-dressing reduced the yield of saleable 
potatos by 1'2 per cent., and increased the percentage of small potatos 
by 1 per cent., and diseased by 0*2 per cent. 
The extremely dry season may have had a good deal to do with these 
results.

Table No. 5. — To try the effects of potash on the crop, also different 
kinds of potassic manures and in different quantities. 
(a) Farmyard manure, sulphate of ammonia and superphosphate 
versus the same manures with the addition of 1 cwt. of muriate of 
potash. 
The potash plot gave an increase of 11^ cwt. of saleable potatos and 
3 cwt. more chats per acre, the net gain being Gs. 9i., but the 
percentage of saleable potatos and chats varied only very slightly. 
The haulm on the muriate of potash plot was stronger and kept green
