Abstract
The current study aims to investigate the effects of calcium oxide nanoparticles (CaO NPs) on fenugreek (Trigonella foenum-graecum L.) and its effect on plant growth and development. The CaO NPs were synthesized by co-precipitation method, and their physicochemical properties were characterized by UV–visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Energy dispersive X-ray spectroscopy (EDS). The XRD result demonstrates that the CaO NPs produced had a hexagonal structure with an average crystallite size of 24 nm and nanoparticle aggregations. CaO NPs were successfully synthesized, as evidenced by the appearance of distinct peaks in the UV-Visible spectroscopy, FTIR, and EDS spectra. The seedlings were tested in greenhouse trials for 16 days at two different concentrations (50 mg. L-1 and 100 mg. L-1) to measure the effect of CaO NPs on the growth and development of Trigonella foenum-graecum L. The low concentration (50 mg. L-1) of CaO NPs effectively improved the growth parameters (root and stem length, increased leaf area) and some biochemical aspects such as photosynthetic pigments (chlorophyll a, chlorophyll b, carotenoids, and anthocyanins content) and non-enzymatic antioxidants (phenolic content) as well as enzymatic antioxidant enzymes (SOD and CAT) of the plants. Further, MDA concentration was decreased in the treatment with 50 mg. L-1. The growth stagnated or had no impact or slight effect at high concentrations (100 mg. L-1) on Trigonella foenum graecum L. plants. Finally, we can conclude the growth-friendly effects of CaO NPs at lower concentrations (50 mg. L-1) on Trigonella foenum-graecum L.
