Cadmium (Cd), as the most prevalent heavy metal contaminant poses serious risks to plants, humans, and environment. The ubiquity of this toxic is continuously increasing due rapid discharge industrial mining effluents excessive use chemical fertilizers. Nanoparticles (NPs) have emerged a novel strategy alleviate Cd toxicity. Zinc oxide nanoparticles (ZnO-NPs) become important NPs used mitigate toxicity abiotic stresses improve crop productivity. plants quickly absorb Cd, which subsequently disrupts plant physiological biochemical processes increases production reactive oxygen species (ROS), causes oxidation cellular structures significant growth losses. Besides this, also leaf osmotic pressure, nutrient uptake, membrane stability, chlorophyll synthesis, enzyme activities, leading reduction in biomass Though possess an excellent defense mechanism counteract toxicity, not enough counter higher concentrations Applying Zn-NPs has proven potential mitigating effects Cd. ZnO-NPs photosynthetic efficiency, gene expression, can help stress. Additionally, reduce absorption accumulation complex relationship between ZnO-NPs, osmolytes, hormones, secondary metabolites plays role tolerance. Thus, review concentrates on exploring diverse mechanisms by ZnO plants. In end, identified various research gaps that need addressing ensure promising future findings contribute gaining deeper understanding combating promote safer sustainable remediating Cd-polluted soils. This allows for development eco-friendly approaches remediate soils soil fertility environmental quality.

Abstract With the anticipated foliar application of nanoparticles (NPs) as a potential strategy to improve crop production and ameliorate heavy metal toxicity, it is crucial evaluate role NPs in improving nutrient content plants under Lead (Pb) stress for achieving higher agriculture productivity ensure food security. Herein, Brassica napus L. grown Pb contaminated soil (300 mg/kg) was sprayed with different rates (0, 25, 50, 100 mg/L) TiO 2 ZnO-NPs. The were evaluated growth attributes, photosynthetic pigments, leaf exchange oxidant antioxidant enzyme activities. results revealed that mg/L significantly augmented plant growth, gas attributes. Furthermore, ZnO-NPs showed maximum increase SPAD values (79.1%, 68.9%). (100 ZnO-NPs) also substantially reduced malondialdehyde (44.3%, 38.3%), hydrogen peroxide (59.9%, 53.1%), electrolyte leakage (74.8%, 68.3%), increased peroxidase (93.8%, 89.1%), catalase (91.3%, 84.1%), superoxide dismutase (81.8%, 73.5%) ascorbate (78.5%, 73.7%) thereby reducing accumulation. root (45.7%, 42.3%) shoot (84.1%, 76.7%) concentration respectively, compared control. Importantly, macro micronutrient analysis zinc (58.4%, 78.7%) iron (79.3%, 89.9%), manganese (62.8%, 68.6%), magnesium (72.1%, 93.7%), calcium (58.2%, 69.9%) potassium (81.5%, 68.6%) when control without NPs. same trend observed concentration. In conclusion, we found have greatest efficiency at alleviate induced toxicity on photosynthesis, promising sustainable safety contamination.

Abstract Nanobiofertilizers have emerged as an innovative tool for enhancing crop productivity. In the current research, zinc oxide nanoparticles (ZnONPs) were mycosynthesized using cell-free supernatant of Trichoderma harzianum and optimized physical parameters. Characterization UV-Visible spectroscopy, dynamic light scattering analysis, zeta potential X-ray diffraction (XRD) Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy-EDX, HR-Transmission microscopy confirmed formation ZnONPs with flower-like morphology average size 314 nm. The value was +1.9 mV indicating neutral NPs. FTIR peak at 401 cm −1 revealed presence ZnONPs. XRD analysis hexagonal wurtzite crystalline nature effect 10–1,000 ppm combined liquid bio-slurry (BS) studied on seed germination growth Vigna radiata. Combination 250 BS 1:2 ratio showed 22.6% increase in shoot length well 18.4% root compared to control vitro studies. Vivo pot experiments no significant difference secondary metabolites after 60 days, but increased by 38.9% 46.95% control.

Cadmium (Cd) can harm the yield and quality of vegetables, threatening food safety. Essential microelements such as iron are crucial for plant growth help alleviate heavy metal stress. Recently, nanoparticles have been studied eco-friendly solutions mitigating stress in plants. In present study, (FeNPs) at 0, 100, 300 mg/L were applied soil drenches foliar sprays to tomato plants under cadmium A comparison was made between application methods FeNPs by evaluating parameters plants, including shoot length (SL), root (RL), number branches (NB), leaves per (NL), leaf area (LA), well assessing biochemical antioxidant enzyme parameters. Cd treatment, protein content decreased 24.71%, phenolic flavonoid also due stress, with levels decreasing from 16.07 6.9 µg 0.36 0.16 µg, respectively. Compared drench, 100 significantly improved Cd-stressed when used a spray, leading increases length, fruit weight, fruits, leaves, 42%, 66%, 24%, 173%, 45%, Tomato treated this spray presented increased carotenoid lycopene contents. FeNP reduced accumulation tissues. This technique shows promise alleviating vulnerable vegetable tomatoes.
