Abstract
Under the greenhouse conditions, A pot experiment was conducted to study the effect of foliar spray with silicon and selenium on growth parameters, yield, enzymatic antioxidants, non-enzymatic antioxidant and nutrient content of rice grown under water scarcity. Two soil moisture contents was used (120 and 60 of the saturation point). Foliar spraying of silicon as K2SiO3 at a rate of 1000 mg L-1. and selenium as SeCl2 at a rate of 20 mg L-1. Results showed the decreasing of soil moisture content (SMC) led to decrease of plant height, panicle length, 1000-grain weight, straw, grain and biomass yield and nutrient content within each Si or Se application. Spraying with Si significantly increased plant growth and yield parameters i.e., 1000-grain weight, straw, grain yield, leaf photosynthetic pigments, proline, soluble sugars, and elements compared to other treatments under drought stress. The highest values α.TOC, AsA and GSH of rice plants were obtained with foliar spray of silicon treatment under different soil moisture content
