Soil moisture deficiency is the most important factors of plant growth and development inhibiting. 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, effect of drought stress and fertilizer treatment on number of grain and weight of grain in main branch was significant and according to result drought stress cuse decreased the 12 and 20 % number and weight of grain in main branch. On the other hand, treatments of Silicon fertilizer and Zinc and Silicon mesoporous, respectively, increased the number and weight of grain in the main branch about 19 and 23% compared to the control. None of the traits are not affected by the fertilizer × drought stress.
