Summary

The presented study sought to investigate the response of roselle (Hibiscus sabdariffa L.) plants on the influence of micronutrients nano fertilizer (silicon and zinc), carried out in June 2021 on private orchard fields in the Wasit Province, Iraq. The treatment construction was a perfectly randomized factorial experiment (5 × 5 × 3) in a completely randomized design, done with three replications. The roselle plant received micronutrients spraying with nano fertilizer silicon at concentrations of 0, 3, 6, 9, and 12 ppm and nano zinc with concentrations of 0, 500, 1000, 1500, and 2000 ppm, studying their effects on the plant height (cm), fresh and dry weights (g plant−1), anthocyanin content, total soluble sugars, acidity citric acid, and TFAA of roselle rhizome in yield in single and two-way interactions. The discovery revealed a single application of the previously indicated factors had a considerable influence on the roselle’s development and productivity features, especially at high concentrations. Different outcomes resulted using two-way interactions. The most crucial effect observed was on the total soluble sugars. Based on the results, adding nano silicon and nano zinc to the roselle plant significantly increased all traits, regardless of the vegetable characteristics or chemical content achieved with the highest concentrations using the highest effects, whether alone or with two interactions.

In the roselle plants, adding nano silicon and nano zinc and their interactions highly improved all the vegetative and biochemical traits.
