MANURING EXPERIMENTS WITH PADDY RICE (THIRD YEAR). 
3 
5) 3 plots received a complete manure containing 10 kilo- 
grms. nitrogen, 10 kilogrms. phosphoric acid, and 10 kilogrms. 
potash. 2 
In all these experiments the nitrogen was applied in the form 
of ammonium sulphate, the phosphoric acid as double super¬ 
phosphate, and the potash as carbonate. 
The development of the crops was exactly the same as in 
the two preceding years ; those plants which had received a 
complete manure were the strongest from the beginning to the 
end of the season, they suffered least from transplantation, and 
exhibited a normal green colour; compared with them the 
plants without potash were noticeably inferior, the difference 
becoming perceptible as early as the middle of July; next in 
order were those without nitrogen which, however, turned light 
green and pale at an early period, and ripened a little earlier; 
those which had not been supplied with phosphatic food did 
not differ essentially from the unmanured plants ; though of a 
deep green colour they remained very small, and ripened late. 
The yield of grain and straw of the single plots will be found 
in the appendix. In the average of three equally manured 
plots we obtained the following produce :

These results coincide in their main features very well with 
those obtained in the 2 preceding years, which, for the sake of 
comparison, may be quoted here : 
2 As the same nutrients had been applied in liberal doses in the 2 
preceding years, the above quantities were amply sufficient for a maximum 
produce.
