An experiment on ginger (Zingiber officinale L.) commenced in 2020 using the plant growth incubator of the Laboratories, Department of Biological Sciences, College of Sciences, University of Wasit, Iraq. The study aimed to investigate the effects of mineral sulfur fertilizer at concentrations of 0, 2, 4, 6, and 8 ml/l, and nano-sulfur with concentrations of 0, 1, 2, 3, and 4 ml/l on the plant height, the number of leaves, leaf content of total chlorophyll, leaf area, the tannin of plant, phytic acid, and essential oil of the ginger rhizome. It was evident that a single use of the previously mentioned variables significantly impacted ginger’s vegetative characteristics and chemical composition, particularly at high concentrations. Using the two-way interactions obtained distinct results. The treatment design was a factorial experiment (5 m × 5 m × 3 m) in a completely randomized design with three replicates. The study revealed significant enhancement in all attributes, whether the morphological and biochemical content achieved the highest mineral sulfur and nano-sulfur fertilizer concentrations alone, or in combinations.

In the ginger (Z. officinale L.) plants, adding nano-sulfur fertilizer had a superior effect when in the nano state than in the metal ion sulfur and significantly improved the morphological and biochemical components.
