To study the effect of selenium and salicylic acid on agronomic characteristics of dry land wheat cultivars, an experiment was carried out as factorial based on Complete Randomized Block Design with three replicates at the research field station of Islamic Azad University- Arak, Iran in 2010-2011 cropping season. The experimental factors were including three levels of salicylic acid: without salicylic acid, seed priming in solution of 0.5 mlM salicylic acid and seed priming in solution of 0.5 mlM salicylic acid along with foliar application of salicylic acid at the rate of 1 mlM, selenium (sodium selenite) at two levels: without selenium and with selenium at the rate of 18 g/ha-1 and three dry land wheat cultivars include Azar 2, Sardary and Rasad. The results showed that, Azar 2 cultivar had more grain yield by 19 and 16% as compared with Sardary and Rasad cultivars, respectively. Also the maximum of spike length and harvest index was obtained from Azar 2 cultivar. Foliar application of selenium increased chlorophyll-meter number and grain yield by 8 and 7.5% as compared with control, respectively. Salicylic acid application as seed priming along with foliar application of selenium was increased chlorophyll-meter number and grain yield by 13 and 9% as compared with control, respectively. Maximum and minimum response of grain yield to salicylic acid (seed priming and foliar application) along with spray of selenium was obtained from Azar 2 and Sardary cultivars, respectively. It could be concluded that seed priming of salicylic acid along with foliar application of selenium at three cultivars in dry land condition was led to obtain optimum yield.
