“…The existence of Cu‐MOF‐OCs as nanoparticles explained its potential to overcome the cellular barriers of the cell membrane, traversing across it and subsequently releasing the copper ions hence eliciting cell oxidative stress [51] . Particular attention has been drawn to nanocomposite fungicides due to their high toxicity to fungal cells causing significant reduction in metabolic changes during protein synthesis due to oxidative stress [18] .…”

“…The decrease in the crystallite sizes of Cu‐MOF‐OCs after modification was an indication that the Cu 2+ ions were securely anchored on both the TP and OCs networks by −NH 2 , −OH, and C=O functional groups resulting in the formation of small crystals of Cu‐MOF‐OCs due to their orientation to a limited space [23] . The existence of Cu‐MOF‐OCs as nanoparticles are significant antifungal property in imparting the required toxicity on the target fungi by overcoming the cellular barriers of the cell membrane, traversing across it, and subsequently releasing the copper ions hence eliciting cell oxidative stress [51] …”

Fungal resistance and the environmental degradation posed by conventional fungicides necessitate the need to develop new antifungal agents that can inhibit fungal growth. This study sought to prepare biofungicides by leveraging on the antifungal activity of copper‐metal organic framework (Cu‐MOF) and dialdehyde chitosan (Cs) isolated from black soldier flies (BSF). Cs were oxidized using potassium periodate to obtain dialdehyde Cs (OCs) and thereafter, Cu‐MOF was loaded resulting in Cu‐MOF‐OCs. Fourier Transform Infrared spectrophotometer (FT‐IR) and powder X‐ray diffraction (XRD) confirmed the presence of carbonyl functional groups in OCs and sharp intense peaks associated with Cu that interacted. The changes in surface morphology and the presence of Cu in the MOFs as obtained with Scanning Electron Microscope‐ Energy Dispersive X‐ray (SEM‐EDX), indicated the successful loading of Cu‐MOF on the oxidized Cs. Thermogravimetric analysis (TGA) showed a loss of approximately 31.51 % of the loaded OCs and 40.72 % framework around ∼200 to ∼300 °C and ∼410 to ∼475 °C respectively. The antifungal activity of OCs, Cu‐MOF, and Cu‐MOF‐OCs against Aspergillus brasiliensis and Candida albicans was performed using the plate count method and the results suggested that MOF modulated the antifungal activity exerted by the OCs.

“…This is primarily due to the superior release of organic acids in the combination of chemical fertilizer and microorganism inoculation (Morales-Santos et al, 2023), leading to increased microbial activity and a greater number of microorganisms. Consequently, the fertilizer and water become more readily available for uptake and utilization (Yusefi-Tanha et al, 2023). The combined approach proves more effective in meeting the nutritional needs of baby corn plants consistently, facilitating increased yields, while the microorganisms aid in organic matter decomposition and nitrogen release, thereby enhancing soil fertility.…”

In response to the escalating costs and diminishing efficiency of nitrogen fertilizers, the agricultural community is actively seeking sustainable alternatives that leverage natural nitrogen sources derived from biological N-fixation processes to enhance crop yield. This study investigates the combined effects of Klebsiella quasipneumoniae inoculation and varying nitrogen fertilizer doses on soil fertility, nutrient availability, and the yield and quality parameters of baby corn (Zea mays. L). The study involved the application of five nitrogen levels (0, 75, 150, 225, and 300 kg N ha-1) in conjunction with Klebsiella quasipneumoniae inoculum on HM-4 variety of baby corn, employing a comprehensive experimental design with five treatments and four replications. All treatments demonstrated increased ear count and weights of ear, silk, husk, edible cob, and biomass compared to the control. The study highlights the potential of Klebsiella quasipneumoniae inoculation in synergy with reduced nitrogen fertilizer to enhance total N contents in soil and positively impact baby corn yield and cob quality parameters. Optimal results were achieved with a 50% reduction in nitrogen fertilizer (150 kg N ha-1), emphasizing the importance of integrated nutrient management. The findings contribute valuable insights to sustainable agriculture, offering a promising strategy for increased baby corn production, improved nutritional quality, and environmental conservation. This integrated approach, involving microbial inoculation and nitrogen management, emerges as a key element in modern agricultural practices, promoting both productivity and nutritional content in baby corn crops.

“…Crops are known to transport and bioaccumulate MNPs in edible parts, raising concern for potential human health risks (Deng et al 2020 ; Bajaj et al 2023 ). Therefore, it is important to investigate the potential effects of MNPs on the edible parts of crops (Rui et al 2018 ; Yusefi-Tanha et al 2020a , b , 2023 ). Studies evaluating the effects of n CuO on yield and seed nutritional quality after full life cycle exposure under field conditions are scarce (Wang et al 2021 ).…”

Increased impetus on the application of nano-fertilizers to improve sustainable food production warrants understanding of nanophytotoxicity and its underlying mechanisms before its application could be fully realized. In this study, we evaluated the potential particle size-dependent effects of soil-applied copper oxide nanoparticles (nCuO) on crop yield and quality attributes (photosynthetic pigments, seed yield and nutrient quality, seed protein, and seed oil), including root and seed Cu bioaccumulation and a suite of oxidative stress biomarkers, in soybean (Glycine max L.) grown in field environment. We synthesized three distinct sized (25 nm = S [small], 50 nm = M [medium], and 250 nm = L [large]) nCuO with same surface charge and compared with soluble Cu2+ ions (CuCl2) and water-only controls. Results showed particle size-dependent effects of nCuO on the photosynthetic pigments (Chla and Chlb), seed yield, potassium and phosphorus accumulation in seed, and protein and oil yields, with nCuO-S showing higher inhibitory effects. Further, increased root and seed Cu bioaccumulation led to concomitant increase in oxidative stress (H2O2, MDA), and as a response, several antioxidants (SOD, CAT, POX, and APX) increased proportionally, with nCuO treatments including Cu2+ ion treatment. These results are corroborated with TEM ultrastructure analysis showing altered seed oil bodies and protein storage vacuoles with nCuO-S treatment compared to control. Taken together, we propose particle size-dependent Cu bioaccumulation-mediated oxidative stress as a mechanism of nCuO toxicity. Future research investigating the potential fate of varied size nCuO, with a focus on speciation at the soil-root interface, within the root, and edible parts such as seed, will guide health risk assessment of nCuO.
