“…Previous studies have confirmed the increased availability of Si in soils amended with amorphous silica-based fertilizers (Mills-Ibibofori et al 2019;Oliva et al 2020;Prakash et al 2016). Jeer et al (2020) found that the Si available in the soil increased between 33 and 44% after amending150 and 300 kg ha −1 of ASF to a clay loam soil. The leaf and stalk Si concentrations showed a linear increase in response to fertilization with ASF (Fig.…”

Silicon (Si) fertilization can mitigate biotic and abiotic stresses and increase the yield of sugarcane. Considering the low availability of Si in tropical soils and the large amounts of fertilizer required by Si accumulating crops, concentrated sources of Si with good solubility may lead to more profitable fertilization management. In this context, we assessed the potential of an amorphous silica-based fertilizer (ASF) on increasing the soil availability and uptake of Si by sugarcane, the growth parameters, the stalk and sugar yields, and the damage caused by stalk borer (Diatraea saccharalis F.). Additionally, Si effects on the accumulation of nutrients by sugarcane were evaluated. The field trial was carried out in a randomized block design with four replications. The ASF was applied at five rates (0, 125, 250, 500, and 750 kg ha −1 ). The evaluation of the plants was performed 12 months after planting. Silicon available content in the soil layers assessed (0.0-0.2 m and 0.2-0.4 m) increased with Si fertilization. The Si concentrations in leaves and stalks were up to 5-and eightfold higher in ASF-amended plants than the control. The Si fertilization increased N, P, K, Ca, Fe, Mn, Cu, and Zn concentrations. Sugarcane growth parameters showed a positive relationship with Si in plants; the height and stalk diameter and the dry leaf biomass were 50, 58, and 71% higher in the 750 kg ha −1 ASF compared to the control, respectively. ASF also increased the contents of fiber, total sugar, and recoverable sugar. The accumulation of Si in the stalk reduced significantly the damage caused by the stalk borer. The ASF rates increased the yield of stalks, total and recoverable sugar, and the stalk borer's resistance, having great potential to boost sugarcane performance in Si-depleted soils in northeast Brazil.

“…However, it can be incorporated into management practices, specifically with the use of manufactured or naturally occurring Si fertilisers (Haynes, 2014). Unlike pesticides, Si intervention is unlikely to negatively impact other parts of the ecosystem (Jeer et al, 2021;Ma & Yamaji, 2006). More importantly, hydroponic studies show that supplying plants with Si causes rapid (<72 hr) accumulation of Si defence against herbivores (Waterman et al, 2021).…”

Metadata information-description of the 3 data files."ALL DATA" -Column P "Herbivore growth rate". NA values correspond to plants that were not inoculated with herbivores; therefore the herbivore growth rate could not be calculated.-Column U-AG corresponds to all the different alkaloid types produced by the different endophyte strains; therefore "NA" in the data set denotes the lack production of the specific alkaloid type.

Silicon (Si) has never been acknowledged as a vital nutrient though it confers a crucial role in a variety of plants. Si may usually be expressed more clearly in Si-accumulating plants subjected to biotic stress. It safeguards several plant species from disease. It is considered as a common element in the lithosphere of up to 30% of soils, with most minerals and rocks containing silicon, and is classified as a “significant non-essential” element for plants. Plant roots absorb Si, which is subsequently transferred to the aboveground parts through transpiration stream. The soluble Si in cytosol activates metabolic processes that create jasmonic acid and herbivore-induced organic compounds in plants to extend their defense against biotic stressors. The soluble Si in the plant tissues also attracts natural predators and parasitoids during pest infestation to boost biological control, and it acts as a natural insect repellent. However, so far scientists, policymakers, and farmers have paid little attention to its usage as a pesticide. The recent developments in the era of genomics and metabolomics have opened a new window of knowledge in designing molecular strategies integrated with the role of Si in stress mitigation in plants. Accordingly, the present review summarizes the current status of Si-mediated plant defense against insect, fungal, and bacterial attacks. It was noted that the Si-application quenches biotic stress on a long-term basis, which could be beneficial for ecologically integrated strategy instead of using pesticides in the near future for crop improvement and to enhance productivity.
