To evaluate the effect of different form of silicon and zinc on the yield of chickpea plant under drought stress, this present experiment was carried out in Research Farm of Maragheh University during 2018 growing season as Split-plot experiment conducted based on a randomized complete block desing with three replications. Main factor in the three levels of droughr stress (90, 60 and 30 % of the field capacity) and a sub factors included control (no fertilizer application) and Zinc sulfate, Silicon, Silicon + Zinc sulfate and Silicon- Zinc mesoporous. According to the results, effect of drought stress on Grain weight/shell weight and number of unfilled pod was significant and with increasing stress intensity, the Grain weight/shell weight and the number of unfilled pods decreased 9 and 46 %. Also effect of fertilizer treatment was significant on number of unfilled pod was significant. Application of fertilizer treatments, especially zinc sulfate, reduced the number of unfilled pods about 52%. None of the traits are not affected by the fertilizer × drought stress.
