The role of vitamin E and calcium oxide nanoparticles in yield of wheat irrigated with saline water

الملخص

Abstract:     Afield experiment  was carried out during 2024  growing season ,to investigate the influence of foliar application of vitamin E and concentration of( 0,100,200) mg.l^-1 in addition to Calcium oxide nanoparticles ( 0,50,100) mg.l^-1 on yield wheat prameters of to salt stress( Nacl )at three levels (0,4, 8)ds.m^-1 .the experiment was conducted in factorial Randomized completely Blook Design (R.C.B.D) whith three replicates and means were compared  Duncan s test at probability of 0.05. Results indicated that salt stress(Nacl) levels  from 0 to 8 ds.m^-1 reduced significantly the average of growth yield parameters (Number of spikelets ,weight of 1000 grian , grian yield ,biological yield ).Moreover , application of vitamin E and Calcium oxide nanoparticles increased significantly the average of growth yield parameters above,and had reduced the adverse effect of salt stress particulary 200 mg.l vitamin E and 100 mg.l ^-1 Calcium oxide nanoparticles.
