Yield components of rice plants at 120 DAT with different Si method applications at 55 and 75 DAT.

Treatment	Panicle length (cm)	Spikelets per panicle	Filled grain (%)	1,000-grain weight (g)	Yield (tha^-1)
Control	24.77b	175b	89.53b	26.03b	4.44c
Topdressing	26.53a	175b	91.87b	28.13a	6.15b
Foliar spray	26.67a	200a	95.20a	26.33b	6.80a
LSD ()	3.33	5.88	8.52	2.12	6.84
CV	5.64	8.63	4.08	3.49	4.21

Mean values followed by the same letters within a column are not significantly different at by the LSD test. CV: coefficient of variation.
