MANURING EXPERIMENTS WITH PADDY RICE.

about 40 centimetres. On March 31st, the slaked lime was 
incorporated, 2 days afterwards on all plots of the 6th series the 
sodium phosphate and potassium carbonate, and again after 
2 days the genge was sown. On the other plots the sodium 
phosphate and potassium carbonate were spread and harrowed 
in on June 22nd, and after an interval of 4 days, during which 
the latter manures had been absorbed, the ammonium sulphate 
was incorporated with the muddy soil. 
The plants for the experiments had been raised in seed beds 
in the usual way and were transplanted into the plots on June 
29th, when they were about 5 inches high. Each plot received 
16 bundles of healthy uniform plants, in all 240 plants. The 
variety used, known as Satsuma rice has a medium length of 
vegetation and is distinguished by the production of much grain 
in proportion to the straw, but the size of the grain is not large. 
Irrigation was at once commenced after transplantation. The 
treatment during the growth was just the same as is customary 
in our neighbourhood. 
Already a fortnight after transplantation the different manures 
manifested distinct effects. The unmanured plants remained 
small and became pale, the genge plants were a little more 
greenish, while all others appeared at that time vigorous and 
healthy. In the course of time the unmanured plots also 
acquired a dark green colour, but all those plants which had 
received besides phosphoric acid less than 10 kilograms of 
nitrogen per tan as well as those with green manure became 
light green, and ripened about 12 days earlier than on the 
other plots. Those with no phosphoric acid did not exhibit the 
least difference from the unmanured plots during the whole 
season, and ripened also late. 
During the time of flowering, which commenced on August 
27th and was at its height on Septenber ist-8th, the weather 
was rather unfavourable, rainy, and cold ; and the terrific 
hurricane that blew over the country on the night of the 11th- 
12th of Septenber did considerable damage. Many of the 
panicles dried up in consequence of the injuries done by that
