“…Also, primed Fe 3 O 4 -NPs in this experiment offered ideal conditions for the seeds to improve metabolic activity during water absorption, resulting in Fe 3 O 4 -NPs-primed seeds being further along in the germination process than the control seeds. According to the researchers, the usage of Fe 3 O 4 -NPs resulted in an increase in GP, GR, and SI in the plant due to the features of nanoparticles and their enhanced solubility. , On the other hand, the researchers’ studies revealed that the GR had an inverse connection with MGT, implying that the application of Fe 3 O 4 -NPs boosted the seed GR rather than lowering MGT. The higher the seed GR, the shorter the MGT …”

The coating of Fe 3 O 4 -NPs with SM and HS is a new strategy to increase the efficiency of nanofertilizers and improve the quality and resistance of plants against environmental stresses. In this study, aqueous extracts of spinach and guar were used for the green synthesis of Fe 3 O 4 -NPs and CuO-NPs, respectively. The surface of the Fe 3 O 4 -NPs was then coated with SM and HS. UV− vis, thermogravimetric analysis, Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and dynamic light scattering analyses all confirmed the formation of nanoparticles. The first experiment was carried out as a factorial in a completely randomized design. The effect of nanoparticles and determination of the optimal concentration of Fe 3 O 4 -NPs, SM, HS, Fe 3 O 4 -SM, and Fe 3 O 4 -HS with concentrations (control, 25, 50, 75, and 100 mg/L) and two methods of application (seed priming and addition to planting medium) were determined. The results showed that seed priming with 75 mg/L Fe 3 O 4 -NPs and single-stranded and multibranched polyamines improves germination and increases the dry matter content and seedling length. Then, a pot test was performed for the effects of Fe 3 O 4 -NPs and single-branched and poly branched polyamines under CuO stress conditions. The factors were six polymers (control, Fe 3 O 4 , SM, Fe 3 O 4 -SM, HS, and Fe 3 O 4 -HS) and 60, and 120 μL). Under stress conditions, the application of Fe 3 O 4 -HS caused an increase of 34.11, 41, 39.37, and 68.25% in the activity of CAT, POX, PPO, and proline, respectively, and a decrease of 46 and 33.33% in MDA and hydrogen H 2 O 2 compared to the control treatment. Also, the use of NPs under stress conditions caused more absorption of N and Fe by the plant. Consequently, the plant's resistance to CuO stress conditions increased.

“…Early germination can be triggered by microelement nanomaterials in most plants (Kim et al, 2015). Nanomaterials can penetrate through seed coat and enhance water absorption and utilization (Alkhatib et al, 2021). However, seed dressing with nZVI didn't promote the germination in our observations.…”

Rhizosphere effect of nanoscale zero‐valent iron (nZVI) is crucial but little reported. Maize seeds were dressed with four nZVI concentrations (0, 1.0, 1.5, 2 g kg−1) and inoculated with arbuscular mycorrhizal fungus (AMF) (Funneliformis mosseae). The SEM images illuminated that excessive nZVI particles (2 g kg−1) were agglomerated on the surface of hyphae and spore, causing severe deformation and inactivation of AMF symbionts and thereafter inhibiting water uptake in maize seedlings. This restrained the scavenging effects of enzymatic (superoxide dismutase, peroxidase) and non‐enzymatic compounds (proline & malondialdehyde) on ROS, and leaf photoreduction activity and gas exchange ability (p < 0.05). Interestingly, the inoculation with AMF effectively alleviated above negative effects. In contrast, appropriate dose of nZVI, that is, ≤1.5 g kg−1, can be evenly distributed on the hyphae surface and form the ordered symbionts with AMF. This help massively to enhance hyphae growth and water and nutrient uptake. The enhanced mycorrhizal infection turned to promote rhizosphere symbiont activity and leaf Rubisco and Rubisco activase activity. Light compensation point was massively lowered, which increased photosynthetic carbon supply for AMF symbionts. Particularly, such priming effects were evidently enhanced by drought stress. Our findings provided a novel insight into functional role of nZVI in agriculture and AMF‐led green production.

“…Thick and thin micrographs of radicles and leaflets of 5 nm NPs-treated seeds (30 mg/L concentration) and 10 nm NPs (30 mg/L concentration) showed structural and ultrastructural deformation. Thus, it was suggested that the toxicity and the bioaccumulation of Fe 3 O 4 NPs were size and concentration dependent [127]. Magnetic NPs also showed remediation potentials in Cu-polluted soil-plant systems.…”

New advances in nanotechnology are driving a wave of technology revolution impacting a broad range of areas in agricultural production. The current work reviews nanopesticides, nano-fabricated fertilizers, and nano activity-based growth promoters reported in the last several years, focusing on mechanisms revealed for preparation and functioning. It appears to us that with many fundamental concepts have been demonstrated over last two decades, new advances in this area continue to expand mainly in three directions, i.e., efficiency improvement, material sustainability and environment-specific stimulation functionalities. It is also evident that environmental and health concerns associated with nano agrochemicals are the primary motivation and focus for most recent work. Challenges and perspectives for future development of nano agrochemicals are also discussed.
