Influence of Rice Husk Biochar and Its Application Methods on Silicon Dynamics and Rice Yield in Sandy-Loam Soil

Table 3

Effect of RHB application methods on the mean porewater Si concentration.

Application method	Rate (t ha^−1)	Si concentration (mg L^−1)
		Vegetative	Reproductive	Maturity
Control	0	9.20 ± 1.16b	10.74 ± 1.26b	1.55 ± 0.72b
LSA	5	9.11 ± 1.92b	10.22 ± 1.22b	2.71 ± 0.81a
TMA	5	10.05 ± 1.41b	10.48 ± 1.41b	1.31 ± 0.61b
TMA	10	9.60 ± 0.96b	9.31 ± 2.39b	1.63 ± 0.63b
WMA	5	10.33 ± 1.60ab	13.55 ± 1.67a	1.84 ± 1.02b
WMA	10	12.83 ± 2.53a	14.25 ± 4.22a	1.92 ± 0.87b

Note. Means in the same column and growth stage in the same row followed by the same letters are not significantly different from each other at . LSA: localized spot application, TMA: top-mixed application, and WMA: whole-mixed application.
