Abstract. The aims of this study were to investigate the effects of drought stress (full irrigation as control, irrigation up to 50 seed ripening and flowering) and foliar application of iron nano-chelate and fulvic acid compounds on the quantitative and qualitative yield of two sesame (Sesamum indicum L.) genotypes (Dashtestan and Halil). A factorial split plot experiment was conducted based on randomized complete block design (RCBD) with three replications at Shahed University, Tehran, Iran, for two consecutive years. Results indicated that the effects of drought stress, foliar application, and genotype were significant on number of capsule, number of seed, 1000-seed weight, grain yield, biological yield, LAI, number of leaf, oil percent, oil yield, and fatty acid components. Severe drought stress significantly decreased number of capsule, number of seed, 1000-seed weight, grain yield, biological yield, LAI, and number of leaf in comparison to non-stress conditions in the two growing seasons. Co-application of iron nano-chelate and fulvic acid was the most effective treatment, which enhanced number of capsule, number of seed, 1000-seed weight, grain yield, biological yield, LAI, and number of leaf in compared to the control treatment. In the foliar application × genotype interaction effects, the highest grain yield was achieved in Halil genotype under co-application of iron nano-chelate and fulvic acid in the first year (2507.2 kg.ha-1 ) and foliar application of iron nano-chelate in the second year (2712.7 kg.ha-1 ). The highest LAI
