Abstract :
In order to investigate the effect salicylic acid and ascorbic acid on relatively watercontent, yield and yield components of wheat in dry land condition, an experiment was carried out as complete randomized block design with four replicates at a field in Hendoudar city, in 2014-2015. Experimental treatments were included, without foliar application (control), foliar application withwater distillate, foliar application with 100 and 200 mg/Lit ascorbic acid, foliar application with 100 and 200 mg/Lit salicylic acid, foliar application with 100 mg/Lit ascorbic acid along with 100 mg/Lit salicylic acid, foliar application with 100 mg/Lit ascorbic acid along with 200 mg/Lit salicylic acid, foliar application with 200 mg/Lit ascorbic acid along with 100 mg/Lit salicylic acid and foliar application with 200 mg/Lit ascorbic acid along with 200 mg/Lit salicylic acid. The result showed that, the maximum of number of seed per spike and protein percentage was obtained from foliar application with 200 mg/Lit ascorbic acid along with 200 mg/Lit salicylic acid. Foliar application with 200 mg/Lit ascorbic acid along with 200 mg/Lit salicylic acid increased the1000 grains weight 17% as compared to control. The maximum of relative water content in leaf was record from foliar application with 100 mg/Lit salicylic acid along with 200 mg/Lit ascorbic acid. The highest grain yield (1712.5 kg/ha) was obtained from foliar application 200 mg/Lit salicylic acid along with 100 mg/Lit ascorbic acid. It could be concluded that foliar application of salicylic acid along with ascorbic acid in drought stress condition was led to obtain quality and quantity optimum yield.
