“…CdO NPs decreased CO2 absorption and also inhibited energy transportation from PSII to Calvin cycle in barley (Večeřová et al 2016). CdS NPs reduced the photosynthetic activities in Euglena gracilis by causing cell death (da Rocha et al 2020). Photosynthesis, transpiration rate, and also stomatal conductance decreased in soybean and maize plants subjected to La2O3 NPs, however, these adverse effects were more severe in maize (C 4 plant), compared to soybean (C3 plant) (Liu et al 2020).…”

“…The combined application of biochar and Ag NPs led to reduced negative impacts on rice plants, in comparison to plants only treated with Ag NPs; in fact, biochar amendment ameliorated the toxic effects of Ag NPs on photosynthetic and physiological parameters in these plants (Abbas et al 2019). Treatment with a low concentration of ZnO NPs with amended citric acid increased the growth of cowpea (Vigna unguiculata L.) (Cyriac et al 2020). The combination of diuron and CNTs also increased the growth of the green microalga Chlorella vulgaris (Schwab et al 2013).…”

“…For example, there are studies that nanofertilizers release nutrients in up to two months, which, when compared to similar fertilizers that release in up to 10 days, have a great advantage. Another positive point of having a nutrient management system is that these elements are not lost to the environment (CYRIAC et al, 2020).…”

The adequate bioavailability of nutrients to plants is among the various difficulties of the agricultural sector. Thus, the existence of mechanisms for controlled release of the nutrients is essential for planting, as well as novel techniques that do not cause adverse effects. The use of nanotechnology in agriculture can bring many benefits, such as better use of nutrients by plants, reducing waste. Nanofertilizers are an emerging technology and a constantly expanding class of agrochemicals, representing possible solutions to the development of sustainable agriculture. Based on this, the present work aims to update and discuss some relevant topics about these nanomaterials, such as different synthesis approaches, possible mechanisms for the capture of nanofertilizers by plants, and the advantages and limitations of using these materials. Also, an overview of the main literature in the area is presented approaching current studies that use green chemistry concepts.

“…In this respect, several studies are carried out to determine the role and usage of nanofertilizers in the plant production. Biologically synthesized ZnO-NPs were employed for determining the role of metal oxide nanoparticles, on the seed germination of Oryza sativa L (rice) and Vigna unguiculata L (pea) upon measuring their germination index and root growth [12]. ZnO nanoparticle has been biologically synthesized by using Ganoderma lucidum extract and their nanofertilizer properties are studied on Lepidium sativum [13].…”

A simple cost-effective sono-chemical method was used for the synthesis of gCN/TeO2-ZnO ternary (2%, 5%, and 10%) nanocomposites, having crystallite size of 12 nm. FE-SEM and transmission electron microscopy images revealed the formation of core–shell type nanocomposites with an average size of 50 nm. Further, E. coli MTCC 443 strain is used as a model organism to study the antibacterial activity of the prepared nanocomposites, using disc diffusion method. Among all the concentrations, 2% gCN/TeO2-ZnO showed maximum zone of inhibition of 23 ± 0.10 mm and its antibacterial activity is like third-generation antibiotic cefotaxime. In addition, the prepared nanocomposites were used as nanofertilizer for the growth of gram seeds Chickpea (Cicer arietinum). The effect of nanocomposite concentration and its sterilising properties are studied on the rate of germination of Chickpea using both in vitro and in vivo studies (pot study). The root length of the gCN/TeO2-ZnO treated plants showed increase in seed germination (3.30 cm) compared to untreated plants (3.22 cm). In addition, enhancement in the shoot length about 28% is noticed in pot studies, compared to control batch samples. The accumulation of nanomaterial in plant roots was confirmed using SEM-EDX and ICP-MS. Finally, a 14-day experiment was conducted to ascertain the role of gCN/TeO2-ZnO in the controlled release of nutrients from the synthesised nanofertilizer. Owing to its excellent water holding capacity, sterilizing properties, and low toxicity this material can be used as a growth promoter in plants.
