The first factor includes water deficit stress at four levels, stress at the vegetative growth stage, stress at the reproductive growth stage, stress at seed filling stage, and no stress (control). The second factor is foliar spraying of ascorbic acid, salicylic acid, nano-micronutrient chelate fertilizer, and control (water spray). Water deficit stress at different growth stages decreases plant height, a number of laterals, dry weight, fresh weight of vegetative organs, root volume, fresh, and dry weight of root and root length, compared to the control. However, electrolyte leakage and leaf temperature are increased. Results show that water deficit stress at post-anthesis stage decrease grain yield via decreasing 1000-grain weight. Foliar application of growth regulators by improving yield components, increase the yield of quinoa under water deficit stress condition. Therefore, according to the results, it seems that the use of stress modulators in quinoa under water deficit stress with stimulating growth and metabolism, lead to water deficit stress tolerance.
