Figure Lengend Snippet: Physicochemical characterization of synthesized nano-silica and nano-zinc. A Dynamic light scattering (DLS) analysis of hydrodynamic diameter distribution, B zeta potential profiles, C X-ray diffraction (XRD) patterns, and ( D ) Fourier transform infrared (FTIR) spectra. Results confirm the nanoscale size distribution, surface charge stability, crystalline structure, and characteristic functional groups of the synthesized nanoparticles

Article Snippet: In contrast, nano-zinc showed absorption bands at ~ 3400 cm−1 (O-H stretching), ~ 1600 cm−1 (H-O-H bending of adsorbed water), and characteristic Zn-O vibrations in the 500–600 cm−1 region (Fig. D).

Figure Lengend Snippet: Effect of nano-silica and nano-zinc on SPAD index and root dry weight of dill ( Anethum graveolens L.) under irrigation (Ir) and drought stress (D) during two growing seasons. Panels A and C show data from 2023, while panels B and D correspond to 2024. SPAD index is presented in panels A (2023) and B (2024), and root dry weight in panels C (2023) and D (2024). Treatments included Si25 and Si100 (25 and 100 mg L⁻¹ nano-silica) and Zn25, Zn50, and Zn100 (25, 50, and 100 mg L⁻¹ nano-zinc). Values represent mean ± SE ( n = 3). Different letters within each panel indicate significant differences at p < 0.05 according to Fisher’s LSD test

Figure Lengend Snippet: Effect of nano-silica and nano-zinc on seed yield and harvest index of dill ( Anethum graveolens L.) under irrigation (Ir) and drought stress ( D ) across two growing seasons. Panels A and C present results from 2023, while panels B and D correspond to 2024. Seed yield is shown in panels A (2023) and B (2024), and harvest index in panels C (2023) and D (2024).
