To investigate the effects of melatonin and zinc sulfate on agronomic traits and grain yield of quinoa cultivars under salinity stress, an experiment was designed and conducted in the 2023 growing season in Kashmar and Bardaskan. The study was laid out as a factorial experiment based on a randomized complete block design with three replications. Treatments included two quinoa cultivars, ‘Red Carina’ and ‘Titicaca’, and seed priming along with foliar application at three levels: control (no application), melatonin, and zinc sulfate. The results showed that in Bardsken with saline water and soil, the protein yield of the Redcarina was 30.02% and that of the Titicaca was 35.39% lower than that of the same varieties in the Kashmar. The seed yield of the Titicaca in the Bardsken was 23.25% and that of the Kashmar region was 25.81% higher than that of the Redcarina in these two regions. In Kashmar, the combined application of seed priming and foliar melatonin increased grain yield by 17.85%, while zinc sulfate also led to an 18.04% increase. Conversely, in Bardaskan, the combined application of seed priming and foliar melatonin and zinc sulfate resulted in grain yield increases of 36.91% and 35.70%, respectively. Within the scope of this research, the use of the ‘Titicaca’ cultivar and the combined application of seed priming and foliar melatonin and zinc sulfate are recommended for enhancing grain and protein yield."
