“…Silica-based nanosystems play a pivotal role in sustainable agriculture. They are being used as nanofertilizers, nanopesticides, and nanocarriers for various biomolecules (Rajiv et al, 2020). The silica is previously known to induce defence responses in Lolium perenne L. against a gray leaf-spot disease caused by Magnaporthe oryzae (Catt.)…”

Engineered nanomaterials (ENMs) are being produced and utilized in certain nanoformulations almost in every sector of development including agriculture. The diverse groups of engineered nanoparticles (ENPs) provide numerous benefits in agriculture, but their bulk and direct delivery pose a serious risk to the plants and ecosystem for a long time. The harmful effects on all the exposed living systems are owing to the variable shape, size, behaviour and toxic properties of ENPs. The accumulated ENMs in plant tissue may lead to biomagnification at a higher trophic level causing severe toxicity. The hazardous effects of these entities can be minimized with their controlled, specified and targeted delivery to the crop plants. Such smart-delivery systems as Ehrlich’s ‘magic bullets’ are being demonstrated for nutrients and growth enhancers, fertilizers, pesticides and weedicides; as well as biomolecules in plant genetic engineering. This review summarizes the benefits of ENMs and ENPs in plant protection to increase crop productivity, their targeted delivery suggesting sustainable utilization, and the available information on phytotoxicity.

Salinity is an abiotic stress that affects agriculture by severely impacting crop growth and, consequently, final yield. Considering that sea levels rise at an alarming rate of >3 mm per year, it is clear that salt stress constitutes a top-ranking threat to agriculture. Among the economically important crops that are sensitive to high salinity is tomato (Solanum lycopersicum L.), a cultivar that is more affected by salt stress than its wild counterparts. A strong body of evidence in the literature has proven the beneficial role of the quasi-essential metalloid silicon (Si), which increases the vigor and protects plants against (a)biotic stresses. This protection is realized by precipitating in the cell walls as opaline silica that constitutes a mechanical barrier to the entry of phytopathogens. With respect to Si accumulation, tomato is classified as a non-accumulator (an excluder), similarly to other members of the nightshade family, such as tobacco. Despite the low capacity of accumulating Si, when supplied to tomato plants, the metalloid improves growth under (a)biotic stress conditions, e.g., by enhancing the yield of fruits or by improving vegetative growth through the modulation of physiological parameters. In light of the benefits of Si in crop protection, the available literature data on the effects of this metalloid in mitigating salt stress in tomato are reviewed with a perspective on its use as a biostimulant, boosting the production of fruits as well as their post-harvest stability.

“…Studies have shown that silica nanoparticles are being used extensively in agriculture because of their unique properties. They easily interact with plants because of the high surface area, solubility, surface reactivity, small size, and easy penetration into biological systems, like plants, compared to bulk forms . Formation of a silicic acid layer reduces the rate of transpiration in plants and enhances drought, temperature, and humidity resistance.…”

Interestingly, it has been reported 19 that NSiO 2 particles can reduce the toxicity caused by heavy metals and NSiO 2 particle application in soybean and rice increased the wax content on the leaf, shoot dry weight, and yield.…”

Application of nanoscale materials in agriculture for various reasons, including plant nutrition, has been an interesting multidisciplinary research component. Among the plant nutrients, silica plays an important role as a quasi-essential nutrient besides enhancing resistance against disease and pests in the plant system. In the present investigation, we report the effects of foliar spray (field experiment) of varied concentrations (250, 500, and 750 ppm) of nanoscale silica (NSiO2) and osic acid (350, 700, and 1050 ppm) on structural and biochemical processes and yield in chilli (Capsicum annuum L.). NSiO2 was prepared using the sol–gel method and characterized by UV–vis spectroscopy, dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). The DLS analysis revealed the size (26.2 nm) and ζ-potential (−43.6 mV) of NSiO2. Significant increases in plant height, chlorophyll content, carotenoids, lycopene, and superoxide dismutase enzymatic activities were recorded with particulate NSiO2 foliar application at 750 ppm. Further, we are the first to report that foliar application of particulate NSiO2 led to the formation of a silicic acid layer on epidermal cells in chilli. Hence, foliar application of particulate nanoscale silica increases the flexural rigidity of epidermal cells, the chlorophyll content, carotenoids, lycopene content, and yield in chilli.
