“…Similar research on other crops also showed that nano-CuO or nano-Se did not negatively influence the studied antioxidants in crops, such as in tomato ( Solanum lycopersicum L.) [ 61 ], florist’s daisy [ 7 ], rice ( Oryza sativa ) [ 62 ], and banana seedlings [ 11 ]. Similar results were reported for other nanofertilizers, such as a ZnO nanofertilizer on maize ( Zea mays L.) [ 53 ] and a K nanofertilizer on squash ( Cucurbita maxima L.) [ 63 ].…”

Strawberry production presents special challenges due the plants’ shallow roots. The rooting stage of strawberry is a crucial period in the production of this important crop. Several amendments have been applied to support the growth and production of strawberry, particularly fertilizers, to overcome rooting problems. Therefore, the current investigation was carried out to evaluate the application of biological nanofertilizers in promoting strawberry rooting. The treatments included applying two different nanofertilizers produced biologically, nano-selenium (i.e., 25, 50, 75, and 100 mg L−1) and nano-copper (i.e., 50 and 100 mg L−1), plus a control (untreated seedlings). The rooting of strawberry seedlings was investigated by measuring the vegetative growth parameters (root weight, seedling weight, seedling length, and number of leaves), plant enzymatic antioxidants (catalase, peroxidase, and polyphenol oxidase activity), and chlorophyll content and its fluorescence and by evaluating the nutritional status (content of nutrients in the fruit and their uptake). The results showed that the applied nanofertilizers improved the growth, photosynthetic pigments, antioxidant content, and nutritional status of the seedlings compared to the control. A high significant increase in nutrient contents reached to more than 14-fold, 6-fold, 5-folf, and 4-fold for Cu, Mn, N, and Se contents, respectively, due to the applied nanofertilizers compared with the control. The result was related to the biological roles of both Se and CuO in activating the many plant enzymes. Comparing the Se with the CuO nanofertilizer, Cu had the strongest effect, which was shown in the higher values in all studied properties. This study showed that nanofertilizers are useful to stimulate strawberry seedling growth and most likely would also be beneficial for other horticultural crops. In general, the applied 100 ppm of biological nano-Se or nano-CuO might achieve the best growth of strawberry seedlings under growth conditions in greenhouses compared to the control. Along with the economic dimension, the ecological dimension of biological nanofertilizers still needs more investigation.

“…Our findings signalize that all the vital components present in SBH, including the Sim contributed efficiently to the improvement of the A. nummularia seedling ability to adapt well to multi-stress and withstand stress harmful conditions through optimizing different plant metabolic processes, cellular division and elongation, and biomass accumulation, allowing plants to perform well [16,17,65,66]. The noticeable enhanced growth of the A. nummularia seedling (length and dry weight of shoots) under soil multi-stress by foliar spray with SBH may be attributed to the increased root activity as an effective mechanism to increase root uptake of water and nutrients from the defective soil tested.…”

When the plant is subjected to stress conditions on saline-calcareous soil, it is severely damaged and may die. Overcoming these saline and calcareous stresses is a challenge for the sustainability of human and animal feeding. During 2020 and 2021, the potential enhancing impacts of treating Atriplex nummularia seedlings with a 1% bee-honey solution enriched with 200 μg silymarin per L of solution (SBH) on plant growth, physiological and biochemical traits, antioxidant systems, and nutritional value under saline-calcareous soil stress conditions were investigated. Foliar spraying of A. nummularia with SBH significantly improved plant growth, root activity, photosynthetic efficiency, leaf cell integrity, soluble protein, osmo-regulators, different antioxidants, and nutritional status, while markers of oxidative stress (H2O2 and O2 •-) and oxidative damage (lipid peroxidation and electrolyte leakage), total phenols, and Na + levels were suppressed. The results of this investigation recommended the utilization of SBH for producing satisfactory plant productivities under salinecalcareous soil conditions.

“…Nanofertilizers have efficiency to reduce the nutrient loss via controlled release and thus may minimize the amount of fertilizer application in the field [ 145 ]. According to the available literature, nanofertilizers are benefiting several crop yields [ 146 , 147 , 148 , 149 ]. Gatahi et al (2015) studied the impacts of nanobiofertilizer in tomato crops affected by Ralstonia solanacearum -caused bacterial wilt disease and its pest-resistant function against wilt disease [ 150 ].…”

The advancement in nanotechnology has enabled a significant expansion in agricultural production. Agri-nanotechnology is an emerging discipline where nanotechnological methods provide diverse nanomaterials (NMs) such as nanopesticides, nanoherbicides, nanofertilizers and different nanoforms of agrochemicals for agricultural management. Applications of nanofabricated products can potentially improve the shelf life, stability, bioavailability, safety and environmental sustainability of active ingredients for sustained release. Nanoscale modification of bulk or surface properties bears tremendous potential for effective enhancement of agricultural productivity. As NMs improve the tolerance mechanisms of the plants under stressful conditions, they are considered as effective and promising tools to overcome the constraints in sustainable agricultural production. For their exceptional qualities and usages, nano-enabled products are developed and enforced, along with agriculture, in diverse sectors. The rampant usage of NMs increases their release into the environment. Once incorporated into the environment, NMs may threaten the stability and function of biological systems. Nanotechnology is a newly emerging technology, so the evaluation of the associated environmental risk is pivotal. This review emphasizes the current approach to NMs synthesis, their application in agriculture, interaction with plant-soil microbes and environmental challenges to address future applications in maintaining a sustainable environment.
