Persian shallot (Allium hirtifolium) is a valuable medicinal plant with widespread applications in the food, pharmaceutical, and hygiene industries. This study was conducted to investigate the effects of magnesium and sulfur fertilizers on the morphophysiological and phytochemical characteristics of Iranian shallot. The experiment was carried out as a factorial based on a randomized complete block design (RCBD) with four replications at a farm in northern Rostamkola (Mazandaran province). The factors included different levels of magnesium sulfate (MgSO) at four rates: 0, 40, 80, and 120 kg/ha (designated as M0, M40, M80, and M120) and bentonite-sulfur (S) at four rates: 0, 300, 600, and 900 kg/ha (designated as S0, S300, S600, and S900). The results showed that the M120S900 treatment led to the highest plant height (87.7 cm), collar diameter (2.25 cm), fresh and dry weight of the plant (21.6 g and 11.8 g/plant), and magnesium concentration (0.58%), showing respective increases of 270%, 66.7%, 151%, 280%, and 176.19% compared to the control. The highest antioxidant activity and sulfur concentration were observed in the M80S300 treatment, with respective increases of 101.5% and 61.7% over the control. The highest total phenol content, equal to 2.27 mg gallic acid per gram of fresh weight, was recorded in the M40S600 treatment, representing a 158.8% increase compared to the control. Moreover, the highest flavonoid content, equal to 0.270 mg quercetin per gram of fresh weight, was observed in the M0S300 treatment, showing a 190.3% increase over the control.
