Abstract: 
This experiment was carried out to investigate effects of foliar application of selenium and different Urea top-dressing methods on agronomic and physiological characteristics of rain fed wheat sardari cultivar during the growing season 2012-2013. Experimental factors were four levels of different Urea top-dressing methods (without application of Urea top-dressing; application of 60 kg/ha in tillering stage; application of 30 kg/ha in tillering stage combined with 200 mg/Lit before spike emergence; application of 20 kg/ha in tillering stage combined with 200 mg/Lit before spike emergence and 200 mg/Lit in the last spike emergence stage) and three levels of selenium (0, 5 and 10 mg/Lit). The results showed that the foliar application of selenium at 5 and 10 mg/lit decreased cell ion leakage by 6. 7% and 5. 3% compared to control, respectively. The application of 20 kg Urea/ha in the tillering stage combined with twice foliar application in reproductive stage at 200 mg/Lit along with foliar application of 10 mg/Lit selenium increased grain yield by 44. 3% compared to the control and 12% compared to treatment of application 60 kg Urea/ha in the tillering stage. It could be concluded that by applying of 30 kg Urea/ha in the tillering stage combined with once foliar application in reproductive stage can be decreased by 50% Urea fertilizer application and obtain optimum yield.
