Table 3. Analysis of variance of the effects slag-based silicon fertilizer (slag) and application rate of Si (Si-R) on dry weight of rice organs (%).

		F values
Sources of variation	Df	Leaf	Stem	Grain
Slag	1	0.816 ns	0.142 ns	6.41*
Si-R	3	9.93*	11.61*	36.30**
Slag×Si-R	3	0.388 ns	1.03 ns	1.90 ns

Levels of probability: ns  =  non significant, significantly different *p≤0.05 and **p≤0.01.

Levels of probability: ns  =  non significant and *p≤0.05, **p≤0.01.
