To evaluate the effect of foliar application of silicon and zinc on the yield of chickpea under drought stress, This present experiment was carried out in Research Farm of Maragheh University as Split-plot experiment conducted based on a randomized complete block desing with three replications. Main factor in the three levels of drought 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. The results showed that the effect of drought stress on the number of pods in the sub branch was significant and caused decrease the number of pods in the sub branch about 30 %. Also, the effect of fertilizer treatment on the height of the first pod in the sub-branch was significant but on the number of pods in the sub-branch was not significant. All fertilizer treatments increased the pod height from the ground and the application of Zinc sulfate + Silicon caused a significant increase about 13% compared to the control. None of the traits are not affected by the fertilizer × drought stress.
