MANURING EXPERIMENTS WITH PADDY RICE (SECOND YEAR). 
in the preceding year. Wooden frames 2 feet high and 3 feet 
square were sunk into the well mixed soil up to an inch from 
the upper edge, and each of them was furnished on the 
northern side with a tank of a capacity of about 70 litres from 
which each plot was separately irrigated. As to the com¬ 
position of the soil and water, reference may be made to bul¬ 
letin No. 8 (p. 3-5). The variety of rice was that most commonly 
used by the farmers in the neighbourhood and known as shira- 
tama, which has a medium length of vegetation. Each frame 
received on the 23rd of June 16 bundles each of 12 healthy 
plants which had been raised in a seed bed. Compared with 
the experiments of 1889 the plants mere in a more advanced 
state of development containing in 1000 individuals 326.3 grms. 
of dry matter against 85.6 grms. in the preceding year. The 
manures were incorporated with the soil several days before 
transplanting; the potassic and phosphatic manures being given 
first, and 2 days afterwards the nitrogenous fertilizers. Due 
care was, of course, taken to allow the fertilizers to be absorbed 
by the soil before the transplantation and irrigation were 
commenced. The weather was extremely favorable to rice 
throughout the reason, and no injuries were noticed either from 
insects, or from fungi except from smut, which destroyed, 
however, per plot only 3-8 grains and was observed only on 9 
plots. Towards the end of September the irrigation was 
discontinued, and water was given only for two days, as 
usual when the rice was in blossom. The crop was harvested 
on the ist and 2nd of November when the plants were ripe. 
The plants were dried in the sun, and when they were air-dry, 
we weighed the straw, total grain, and hulls, which had not 
been fertilized. Of each of the products weighed samples were 
kept for analysis. 
Each trial was carried out in triplicate.
