Drought stress is one of the most important determinants of performance in plants.To evaluate the effect of foliar application 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. Results showed that, the effect of drought stress on nomber of one grain and weight of grain in sub branch was significant and with Intensity of drought stress, this traits decreased significantly and respectively drought stress Cause decreased about 29 and 34%. Also fertilizer treatment on all of the traits was significant and the highest amount was obtained from Zinc sulfat and Silicon. So that couse increased about 31, 98 and 35% in number of one and two grain and weight of grain in sub branch.
