“…The results showed that obtained concentrations of zinc in 28-homobrassinolides-Zn-NPs and ethephon-Zn-NPs were 0.125 ± 0.07 and 0.141 ± 0.14 ppm, respectively. These results were comparable with the added concentrations of zinc as per the previously published research article 55 . The slight variations in the final concentrations of zinc might be attributed to the leaching of Zn-NPs, during the process of washing and filtration.…”

“…In addition to the plant growth regulator (PGR), Zn-NPs itself act as an important growth promoter of the aromatic medicinal herbs, by enhancing the nutrient absorption capacity of number of essential macro-nutrients. In some previous studies 54 , 55 , researchers reported the similar effects on essential oil contents of Ocimum sanctum and Mentha piperita by the exogenous application of zinc. In another study 56 , scientists mentioned the 4.73% increase in menthol (%) in essential oil of menthol mint at 5.0 mg Zn kg −1 application of doses.…”

Nutrient leaching is a major reason for fresh and ground water contamination. Menthol is the major bioactive ingredient of Mentha arvensis L. and one of the most traded products of global essential oil market. The indigenous production of menthol crystals in developing countries of the world can prove to be the backbone for local growers and poor farmers. Therefore, present research was designed to check the effects of nano-structured plant growth regulators (PGRs) (28-homobrassinolide and ethephon) with reduced leaching potentials on the essential oil and menthol (%) of Mentha arvensis L. The prepared nano-formulations were characterized by Fourier transform infrared (FTIR) spectroscopy, Laser induced breakdown spectroscopy (LIBS), Differential scanning colorimetry-thermal gravimetric analysis (DSC-TGA), Scanning electron microscopy (SEM), Atomic absorption spectrometry (AAS) and Zeta potential and Zeta size analysis. The menthol (%) was determined by modified spectrophotometric and gas chromatographic (GC) method. The highest essential oil (%) was obtained by the application of 28-homobrassinolide-Zn-NPs-L-II (0.92 ± 0.09%) and ethephon-Ca-NPs-L-III (0.91 ± 0.05%) as compared to the control (0.65 ± 0.03%) and blank (0.62 ± 0.09%). The highest menthol (%) was obtained by applying 28-homobrassinolide-Ca-NPs-L-I (80.06 ± 0.07%), 28-homobrassinolide-Ca-NPs-L-II (80.48 ± 0.09%) and 28-homobrassinolide-Ca-NPs-L-III (80.84 ± 0.11%) and ethephon-Ca-NPs-L-III (81.53 ± 0.17%) and ethephon-Zn-NPs-L-II (81.93 ± 0.26%) as compared to control (67.19 ± 0.14%) and blank (63.93 ± 0.17%).

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.

Complexation of micronutrients with complexing agents reduce undesirable reactions of fertilizers in soil water system. In the form of complex structure nutrients remain available to plants in the useable form. Nanoform fertilizer enhances the surface area of particles and less amount of fertilizer contact with large area of plant roots which reduce fertilizer cost. Controlling release of fertilizer using polymeric material like sodium alginate makes agriculture practices more efficient and cost effective. Several fertilizers and nutrients are used at a large scale to improve crop yields globally and almost more than half goes to waste. Therefore, there is a dire need to improve plant-available nutrients in soil, using feasible, environmentally friendly technologies. In the present research, complexed micronutrients were successfully encapsulated using a novel technique at nanometric scale. The nutrients were complexed with proline and encapsulated using sodium alginate (polymer). Sweet basil was subjected to seven treatments over three months in a moderately controlled environment (25 °C of temperature and 57% of humidity) to study the effects of synthesized complexed micronutrient nano fertilizers. The structural modifications of the complexed micronutrient nanoforms of fertilizers were examined, through X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The size of manufactured fertilizers was between 1 and 200 nm. Fourier transform infrared (FTIR) spectroscopy stretching vibration peaks at 1600.9 cm−1 (C=O), 3336 cm−1 (N–H) and at 1090.2 cm−1 (N–H in a twisting and rocking) corresponds to the pyrrolidine ring. Gas chromatography–mass spectrometry was used to analyze the chemical makeup of the essential oil of the basil plants. Essential oil yield of basil plants increased from 0.0035 to 0.1226% after treatments. The findings of the present research show that complexation and encapsulation improve crop quality, essential oil yield, and antioxidant potential of basil.
