Drought is one of the major abiotic factors that limit agricultural crop production. There are several approaches to counteract the effect of water stress together with silicon application, a non essential beneficial element. It is accumulated in plants at a rate comparable to those of other macronutrients. The study was conducted to test the ameliorative effect of silicon (Si) on a wheat cultivar, Sehar-2006; under water stress in rain protected net house conditions. Initially the nursery was raised in prewashed sand and then transplanted in pots each containing Johnson's nutrient solution as a medium of plant growth. There were four treatments: Well watered (WW), Drought at -0.6 Mpa (DD), Well watered + Si @ 150 mgL$^{-1}$ (WW+Si) and Drought at -0.6 Mpa + Si (DD+Si). The experiment was laid out in CRD with 5 replications. Polyethylene glycol (PEG 8000)  0 and 19g were dissolved in 100ml of half strength Hoagland's nutrient solution separately to create water stress treatments and of control and -0.6Mp Silicon was added as sodium silicate (Na2SiO3.H20). Plants were harvested 45 days after transplanting. Difference (LSD) test was applied to treatment means at \mbox{5\,\%} probability to observe the response of wheat to silicon application under moister stress Silicon applied wheat plants depicted marked enhancement in root shoot fresh and dry weights in comparison to plants grown without Si. More over, they maintained higher water status with increased leaf water potential and relative water contents and higher chlorophyll contents. It was concluded that Si may be beneficial to improve the growth of wheat via change in the physiological and biochemical traits.
