“…Plants can induce defense responses against oxidative stress by activating the non-enzymatic antioxidants, which represent the second line of defense against ROS, hydrophilic molecules (ascorbate, glutathione), and lipophilic metabolites (carotenoids, α-tocopherol; Racchi, 2013; Suzuki et al, 2014; Gowayed et al, 2017) Ascorbate is a water-soluble antioxidant synthesized in mitochondria. It can translocate to other cell compartments by two different pathways.…”

Silicon (Si) is the second most abundant element in soil, where its availability to plants can exhilarate to 10% of total dry weight of the plant. Si accumulation/transport occurs in the upward direction, and has been identified in several crop plants. Si application has been known to ameliorate plant growth and development during normal and stressful conditions over past two-decades. During abiotic (salinity, drought, thermal, and heavy metal etc) stress, one of the immediate responses by plant is the generation of reactive oxygen species (ROS), such as singlet oxygen (1O2), superoxide (O2−), hydrogen peroxide (H2O2), and hydroxyl radicals (OH), which cause severe damage to the cell structure, organelles, and functions. To alleviate and repair this damage, plants have developed a complex antioxidant system to maintain homeostasis through non-enzymatic (carotenoids, tocopherols, ascorbate, and glutathione) and enzymatic antioxidants [superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX)]. To this end, the exogenous application of Si has been found to induce stress tolerance by regulating the generation of ROS, reducing electrolytic leakage, and malondialdehyde (MDA) contents, and immobilizing and reducing the uptake of toxic ions like Na, under stressful conditions. However, the interaction of Si and plant antioxidant enzyme system remains poorly understood, and further in-depth analyses at the transcriptomic level are needed to understand the mechanisms responsible for the Si-mediated regulation of stress responses.

“…In this context, the assimilation and concentration of iron (Fe 3 O 4 ) NPs in pumpkin (Cucurbita maxima) plants were quantified by employing a vibrating sample magnetometer to confirm the presence in roots and leaves (Zhu et al, 2008). Similarly, Fe 3 O 4 NPs can also be measured and tracked in plant organs by exploiting its magnetic properties, such as temperature and magnetic field dependence of magnetization (Govea-Alcaide et al, 2016). The major problem with tracking and translocation of Fe 3 O 4 NPs is associated with the inability to distinguish between intact Fe 3 O 4 NPs and leached ions, which further can be solved by utilizing magnetic particle spectrometry in conjunction with conventional atomic absorption spectroscopy (Ju et al, 2019; Figure 2B).…”

In the current scenario, it is an urgent requirement to satisfy the nutritional demands of the rapidly growing global population. Using conventional farming, nearly one third of crops get damaged, mainly due to pest infestation, microbial attacks, natural disasters, poor soil quality, and lesser nutrient availability. More innovative technologies are immediately required to overcome these issues. In this regard, nanotechnology has contributed to the agrotechnological revolution that has imminent potential to reform the resilient agricultural system while promising food security. Therefore, nanoparticles are becoming a new-age material to transform modern agricultural practices. The variety of nanoparticle-based formulations, including nano-sized pesticides, herbicides, fungicides, fertilizers, and sensors, have been widely investigated for plant health management and soil improvement. In-depth understanding of plant and nanomaterial interactions opens new avenues toward improving crop practices through increased properties such as disease resistance, crop yield, and nutrient utilization. In this review, we highlight the critical points to address current nanotechnology-based agricultural research that could benefit productivity and food security in future.

“…Only soil silicon application increased dry weight of leaves and stems [22,23]. A study carried out in vitro and under greenhouse conditions showed that foliar silicon (silicon dioxide nanoparticles; SiO 2 -NPs) application at a low dosage (50 mg dm −1 ) improved potato growth under salinity stress [24]. According to other authors, silicon in nano-silica, nano clay, or Bentonite increased potato stem diameter and leaf dry weight under greenhouse conditions.…”

“…To date, few studies have focused on the effect of silicon on potato growth. Nearly all experiments were carried out in a hydroponic culture or pots in a greenhouse [19][20][21][22][23][24][25]. There is insufficient knowledge of the effect of silicon on potato growth under uncontrolled environmental conditions in the field.…”

“…A one-year field experiment in Iran showed that foliar application of silicon (silica (SiO 2 ) or sodium silicate nanoparticles (Nano-NaSiO 3 )) increased tuber number per plant and tuber yield of late potato cultivar Agria under salinity stress [26]. Foliar application of silicon is practical only at very low dosages, and starting early in the vegetative stage [19,24,27].…”

As silicon induces abiotic stress tolerance in crop plants, it was hypothesized that foliar silicon application could improve potato growth in an early crop culture. The effect of dosage (0.25 dm3·ha−1 or 0.50 dm3·ha−1) and time (the leaf development stage, BBCH 14–16, tuber initiation stage, BBCH 40–41, or both the leaf development stage and tuber initiation stage) of application of the silicon-based biostimulant Optysil (200 g SiO2 and 24 g Fe in 1 dm3) on potato growth was investigated. Optysil caused an increase in plant height and above-ground plant biomass, enlarged leaf area and decreased leaf weight ratio (LWR), and, as a result, increased tuber number and tuber weight per plant. The effect of Optysil depended on a water deficit during potato growth. The average tuber weight per plant in the cultivation treated with Optysil was higher by 23% under periodic water deficits during potato growth, and by 13% under drought conditions, than in the cultivation without the biostimulant. Dosage of Optysil had a significant effect on above-ground plant biomass and leaf area in the warm and arid growing season. Under drought stress, Optysil at 0.50 dm3·ha−1 stimulated potato growth more than at 0.25 dm3·ha−1. Under periodic water deficits during potato growth, the time of Optysil application affected potato growth more than the biostimulant dosage. The plants produced greater above-ground biomass and had a larger leaf area with two Optysil applications; one in the initial plant growth period (BBCH 14–16), and a repeated treatment in the tuber initiation stage (BBCH 40–41). The tuber weight per plant was positively correlated with the plant height, above-ground plant biomass, leaf area, and LWR.
