“…Silicon is considered a beneficial element for crops, and the adequate supply of Si to sugarcane, a Si-accumulating species, can mitigate biotic and abiotic stresses and promote yield increases (Majumdar and Prakash 2020;Camargo and Keeping 2021). Studies have shown that applying Si to sugarcane can induce tolerance to water stress (Bezerra et al 2019;Camargo et al 2017Camargo et al , 2019, pathogens (Camargo et al 2020;Ramouthar et al 2016), and pests (Atencio et al 2019;Nikpay and Nejadian 2014;Korndörfer et al 2011;Kvedaras et al 2009). Besides, Si can improve crop mineral nutrition and induce biochemical and physiological changes in the plant that positively affect crop performance (Jain et al 2017(Jain et al , 2018Oliva et al 2020).…”

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.

“…There are few reports on the control of sugarcane diseases by Si. Si application is beneficial to control sugarcane ringspot (Leptosphaeria sacchari Breda de Hann) (Raid et al, 1992) and can reduce the severity of sugarcane brown rust (Puccinia melanocephala) (Naidoo et al, 2009). In this study, smut incidence was decreased by 11.57-22.58% (ROC22) and 27.75-46.67% (Badila) through 2 years of Si application.…”

“…Sugarcane is a moderate Si-accumulating crop, with absorption rates higher than that for other minerals except potassium (Meyer and Keeping, 2005). Si plays an important role in the growth and development of sugarcane, thereby improving the quality of sugarcane, and more importantly, enhancing resistance to biological and abiotic stresses (Meyer and Keeping, 2005;Huang et al, 2011;Camargo et al, 2013;Jiang et al, 2014;Bhuiyan and Croft, 2015;Lu et al, 2016;Ramouthar et al, 2016). There are a few reports on the improvement of sugarcane resistance to disease by Si application.…”

“…Silicon amendment can also reduce infections of brown rust ( Puccinia melanocephala H. and P. Sydow), which occurs in several rust-susceptible cultivars in South Africa (Ramouthar et al, 2016). With this in mind, recent research efforts on provision of Si for sugarcane production in South Africa have focussed on identifying sources with high plant-available Si, and which can simultaneously correct soil pH and reduce Al toxicity (Rhodes et al, 2013; Keeping et al, 2014, 2017).…”

“…Hence, in these soils there is an urgent need to replenish plant-available soil Si in order to sustain maximum crop production, reduce abiotic stresses (especially water stress and Al toxicity) (Meyer and Keeping, 2001 ), and as a means to augment plant resistance of more susceptible cultivars to the lepidopteran stalk borer Eldana saccharina Walker (Keeping and Meyer, 2006 ; Kvedaras and Keeping, 2007 ; Kvedaras et al, 2007 ; Keeping et al, 2014 ).

Uptake of Silicon by Sugarcane from Applied Sources May Not Reflect Plant-Available Soil Silicon and Total Silicon Content of Sources

Soils of the tropics and sub-tropics are typically acid and depleted of soluble sources of silicon (Si) due to weathering and leaching associated with high rainfall and temperatures. Together with intensive cropping, this leads to marginal or deficient plant Si levels in Si-accumulating crops such as rice and sugarcane. Although such deficiencies can be corrected with exogenous application of Si sources, there is controversy over the effectiveness of sources in relation to their total Si content, and their capacity to raise soil and plant Si concentrations. This study tested the hypothesis that the total Si content and provision of plant-available Si from six sources directly affects subsequent plant Si uptake as reflected in leaf Si concentration. Two trials with potted cane plants were established with the following Si sources as treatments: calcium silicate slag, fused magnesium (thermo) phosphate, volcanic rock dust, magnesium silicate, and granular potassium silicate. Silicon sources were applied at rates intended to achieve equivalent elemental soil Si concentrations; controls were untreated or lime-treated. Analyses were conducted to determine soil and leaf elemental concentrations. Among the sources, calcium silicate produced the highest leaf Si concentrations, yet lower plant-available soil Si concentrations than the thermophosphate. The latter, with slightly higher total Si than the slag, produced substantially greater increases in soil Si than all other products, yet did not significantly raise leaf Si above the controls. All other sources did not significantly increase soil or leaf Si concentrations, despite their high Si content. Hence, the total Si content of sources does not necessarily concur with a product's provision of soluble soil Si and subsequent plant uptake. Furthermore, even where soil pH was raised, plant uptake from thermophosphate was well below expectation, possibly due to its limited liming capacity. The ability of the calcium silicate to provide Si while simultaneously and significantly increasing soil pH, and thereby reducing reaction of Si with exchangeable Al3+, is proposed as a potential explanation for the greater Si uptake into the shoot from this source.
