Pot experiment was conducted to examine the effect of different levels of salicylic acid (SA) to wheat during November 2015 to March 2016. In this experiment three different levels of SA were used. The different levels of SA were; S0 = 0 mM, S1= 0.2 mM and S2 = 0.4 mM. The experimental results showed that different levels of SA showed significant influence on morphological, yield contributing character and yield of wheat. The foliar application of SA in higher doses at S2 = 0.4 mM increased plant height (63.60 cm), leaf number (10.94), tillers number (2.71), effective tiller numbers plant-1 ( 2.22 ), Membrane Stability (71.53%), spike length (10.45cm), number of spikelet spike-1 ( 18.10 ), number of effective spikelet spike-1 (14.63), number of grains spike-1 ( 35.78 ), grain yield plant-1 ( 1.9 g) and 100 grain weight (4.20 g) compared to S0 = 0 mM and S1= 0.2 mM doses of SA. Therefore, it is suggesting that higher doses of SA increased yield of wheat by improving morphological and yield contributing character.
