The main objective of the research is to assess the role of foliar application of silicon(Si)for enhancing the survival ability of wheat under drought stress through improving its morphology,physicochemical and antioxidants *** were five doses of Si at the rate of 2,4,6 and 8 mM and a *** completion of seeds germination,pots were divided into four distinct groups at various field capacity(FC)levels,such as 100%FC(well-irrigated condition),75%FC(slight water deficit),50%FC(modest water deficit)and 25%FC(severe water deficit stress condition).Foliar application of Si at the rate of 2,4,6 and 8 mM and a control were given after 30 days of sowing at the tillering stage of *** of the present investigation indicated that increasing the level of water deficit stress reduced the morphological parameters(such as root and shoot fresh and dry-biomass weight)and physico-biochemical events((such as chlorophyll contents by estimating SPAD value),total free amino acid(TFAA),total soluble sugar(TSS),total soluble protein(TSP),total proline(TP),CAT(catalase),POD(peroxidase),SOD(superoxide dismutase)and APX(ascorbate peroxidase))of wheat;while foliar application of Si at 6 mM at tillering stage enhanced the drought tolerance in wheat by increasing morphology and physiochemical characters under all levels of drought ***,antioxidants activities in wheat also enhanced by the application of Si at 6 mM under normal as well as all drought stress ***-fore,it may be concluded that foliar application of Si at 6 mM at the tillering stage of wheat is an important indication for increasing the drought tolerance by improving the morphology,physico-biochemical and antioxidants activities in plants under deficit water(drought)conditions.
