Abstract
The current study aims to investigate the positive 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 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 created, 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 and 100 mgL-1) to measure the effect of CaO NPs on the growth and development of Trigonella foenum graecum L. The low concentration (50mgL-1) of CaO NPs effectively improves 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 mgL-1. The growth stagnates or had no impact or slight effect at high concentration (100mgL-1) on fenugreek plants. Finally, we can be concluded the growth-friendly effects of CaO NPs at lower concentration (50 mgL-1) on fenugreek.
