The experiment consisted two types of soil (clay loam soil and clay soil), three soil moisture levels (100 %, 75 % and 50 % of field capacity) and six rates of Si (0, 0.25, 0.5, 01, 1.5, 02mM) and the experiment was conducted in a randomized complete design with 2{u00D7}3{u00D7}6 factorial designs in tree replications. Result indicated that the Si, moisture and soil type had significant effect on most growth parameters, yield components and grain yield of maize. Water deficiency significantly reduced the yield and growth parameters but addition of Si significantly increased growth parameters, yield components and grain yield in both soils. The highest grain yield was obtained at the doses of 0.25 and 0.5mM of Si at 100 % FC and 75 % FC respectively in clay loam soil. Therefore, the highest grain yield was recorded at the doses of 0.25, 2 and 1.5mM of Si under 100 % FC, 75 % FC and 50 % FC in clay soil. All of the examined attributes were increased by increasing Si under three soil moisture levels. In conclusion, priming seeds with 0.25 of Si increased seed germination percentage and more of the parameters of maize.
