“…In this investigation, obtained results revealed that treated A. abrotanum plants by individual trace elements (Fe, Mg, and Mn) resulted in positive effects on the growth, yield, EO composition, nutrients, and their uptake. These effects may be due to trace elements improve plant growth characters and metabolism leading to improve the quantity of the secondary metabolites, i.e., EO (Singh and Dwivedi 2019). Obtained results confirmed by previous literature.…”

“…Trace elements in appropriate dose are essential for plant's growth and development; these play important roles in cell structure and various physiological processes such as photosynthesis, respiration, and different enzymatic activities. Their deficiency or inappropriate presence or absence disturbs the metabolic activities occurring in plants at different stages of development which finally creates imbalance within and show symptoms like chlorosis, necrosis, stunted growth, mottled leaves, and many more affected morphological parameters (Singh and Dwivedi 2019). As these influence different metabolic pathways so affect final product, intermediate products, primary, and secondary metabolites formation.…”

Background and objective Artemisia abrotanum (A. abrotanum) used for against cancer, cough, fever, and tumors; also, it contains essential oil (EO) used in antimicrobial possesses. Trace elements (iron, Fe; magnesium, Mg; and manganese, Mn) play important roles in physiological processes and metabolisms of A. abrotanum plants. In this study, growth, yield, EO, and nutrient contents of A. abrotanum were evaluated under foliar spray of Fe, Mg, or Mn treatments. Materials and methods Plants subjected to different rates of Fe (0, 1, 2, 3, and 4 g/L), Mg (0, 2, 4, 6, and 8 g/L), or Mn (0, 50, 100, 200, and 300 mg/L) as individual experiments. Data were statistically analyzed using ANOVA-1. Results Obtained results showed that Fe (3 g/L), Mg (8 g/L), or Mn (300 mg/L) resulted in the greatest values of growth characters (plant height, fresh and dry weights of aerial parts), EO content (% and mL/100 plants), major constituents of EO (2-hydroxy-1, 8-cineole, β-eudesmol, and camphor), nutrient contents, and their uptakes. Different changes were found in various chemical classes of EO (mono and sesquiterpenes). Conclusion Significant variations were detected in growth, yield, EO, and nutrient contents due to foliar applications of various trace elements such as Fe, Mg, and Mn.

“…The foliar application of nutrients, especially micronutrients, is a common method that meets the needs of higher plants and is more efficient than soil consumption under unfavorable soil conditions in terms of nutrient availability [15]. Foliar fertilization with Zn and B, in addition to increasing leaf numbers, significantly improves the growth, yield and content of plant nutrients and chemical compounds, including pigments, carbohydrates and the oil concentration in iris [16]. The foliar fertilization of trace elements is suitable for field use and has the advantage of low application rates, good efficacy, uniform distribution and very rapid plant responses [7].…”

“…The foliar fertilization of trace elements is suitable for field use and has the advantage of low application rates, good efficacy, uniform distribution and very rapid plant responses [7]. In addition, foliar fertilizers can be designed to meet the specific needs of plants for one or more micronutrients, especially trace elements, and carry out tasks such as correcting deficiencies, strengthening weak or damaged plants, accelerating growth and growing more efficiently [16]. In general, micronutrients applied via foliar spray are just as or even more effective than soil application and result in significantly higher growth and yield [4].…”

Satureja khuzistanica Jamzad is a valuable and endemic medicinal plant. Boron and zinc are essential elements for the vegetative and reproductive growth of plants and have significant effects on yield, essential oil composition and the seed production of plants. To investigate the effects of the foliar application of zinc and boron on the growth, yield, seed production and phytochemical properties of S. khuzistanica, a study was conducted in a factorial experiment with three replicates in two consecutive years based on a randomized complete block design. The foliar application of boron (B) at three concentrations (control or distilled water, 0.4% and 0.8% as H3BO3) and zinc (Zn) at three concentrations (control or distilled water, 0.3% and 0.6% as ZnSO4) was carried out. Our results showed that the foliar application of B resulted in a significant increase in the fresh and dry weights of plants, the dry weight of stems, drug yield, seed yield, seed germination and 1000-seed weight. At the same time, the application of B resulted in a significant decrease in seed emptiness. The fresh and dry weights of plants, drug yield, seed yield, 1000-seed weight and seed germination were also significantly improved by Zn foliar spraying compared to the control. Application of 0.8% B resulted in a significant decrease in seed emptiness by 14.16% and 22.37%, as compared to the control. The foliar spraying of B and Zn improved the total phenolic content, the essential oil content and the yield and antioxidant activity of S. khuzistanica. Moreover, B application generally concentrated more carvacrol in the essential oil (in the first experimental year). In contrast, no significant differences were observed between Zn treatments in carvacrol content and total flavonoids. The use of several microelements, such as B and Zn, could improve both the quantity and quality of S. khuzistanica. Additionally, improvement of seed set and seed quality by the foliar spraying of Zn and B may be useful for growing plants in arid and semi-arid areas.

“…The increase in leaf chlorophyll content may be explained by iron's function in raising the number and size of chloroplasts (Prism et al, 2011) or this might be as a result of the influence of iron on plant activities as a cofactor in the creation of chlorophyll and cytochromes, which are crucial to the processes of respiration and photosynthesis (Focus, 2003). The positive influence of foliar application with iron on volatile oil of tuberose plant might be due to the promotion of plant growth characteristics and metabolism, which would then increase the number of secondary metabolites, such as volatile oil (Singh and Dwivedi 2019). The role of iron fertilizers on volatile oil was given by Pirzad and Barin (2018) on Pimpinella anisum and Khalid and El-Gohary (2020) on Artemisia abrotanum.…”

T WO pot experiments were conducted during the two consecutive growing seasons of 2020 and 2021 at Beni-Suef governorate, Egypt, to compare the influence of biochar treatments (50, 100 and 200 g/pot) combined with foliar application of chelated and nano iron (250 and 500 mg L -1 ) on growth productivity and chemical composition of tuberose plants. The best result for vegetative attributes (leaf number/ plant, leaf fresh and dry weights/ plant), flowering characteristics (flowering date, florets number/ plant, florets fresh weight/ plant, spike length and diameter in addition to fresh weight), vase life, bulbs productivity (number of new bulblets/ plant in addition to fresh and dry weights of the replacement clumps), oil %, photosynthetic pigments and total carbohydrates% in bulbs were obtained due to high level of biochar (200 g/ pot). Regarding iron fertilization treatments, all of the above mentioned qualitative and quantitative attributes of tuberose plants were considerably augmented due to Fe-chelated at 500 mg L -1 followed by 250 mg L -1 then nano-iron at 500 mg L -1 while nano-iron at 250 mg L -1 gave the least values. Spike diameter did not appear to be appreciably changed by any of the four iron fertilization treatments.In regard to the interaction between the two involved factors, the highest of the prementioned characteristics, as well as qualitative and quantitative characteristics values for the component of volatile oil, were obtained from fertilizing tuberose plants with the Fe-chelated at 500 mg L -1 in combination with biochar at 200 g/pot. Finally, adding biochar combined with chelated iron to tuberose plants obviously improved its qualitative and quantitative attributes.
