“…It should be noted that, for the first time, using soluble sources via fertigation with Si is also proven efficient in mitigating the damage caused by the water deficit regime in different soils (Figure 5), which is similar to studies using high Si doses incorporated into the soil (Camargo et al, 2017(Camargo et al, , 2021bClemente et al, 2019). However, most studies with this element do not compare the differences in plant response between soils since they study only one soil.…”

“…The Si role in sugarcane production is an important topic verified by many authors (Camargo et al, 2017(Camargo et al, , 2019(Camargo et al, , 2021bMarchiori et al, 2017;Bezerra et al, 2019). However, there was a lack of greater understanding of the underlying mechanisms that allow a better understanding of the stoichiometric and nutritional components in the plant's response, not just under stress but also without stress.…”

“…The determinations of C and N concentrations were carried out from the dry combustion (1,000 • C) of the LDM and SDM using the elemental analyzer (LECO truspec CHNS), calibrated with the LECO 502-278 standard (C = 45.0%). The P concentration was determined from the nitric-perchloric digestion and the spectrophotometer reading (Carmo et al, 2000). The Si concentration was determined from the alkaline digestion (H 2 O 2 and NaOH) and the reading of the colorimetric reaction with ammonium molybdate using the spectrophotometer (Korndorfer et al, 2004).…”

Studies with silicon (Si) in sugarcane indicate a greater response in productivity in plants under stress, and the underlying mechanisms of Si in the crop are poorly reported. In this context, the benefits of Si in the crop’s stem production are expected to occur at the C:N:P stoichiometry level in plant tissues, benefiting plants with and without stress. However, the extension of this response may vary in different soils. Thus, this research aimed to evaluate if fertigation with Si modifies the C:N:P stoichiometry and if it can increase sugarcane’s nutritional efficiency and vegetative and productive parameters. Therefore, three experiments were installed using pre-sprouted seedlings to cultivate sugarcane in tropical soils belonging to the Quartzarenic Neosol, Eutrophic Red Latosol, and Dystrophic Red Latosol classes. The treatments comprised a 2 × 2 factorial scheme in each soil. The first factor was composed without water restriction (water retention = 70%; AWD) and with water restriction (water retention = 35%; PWD). The second factor presented Si concentrations (0 mM and 1.8 mM) arranged in randomized blocks with five replications. Fertigation with Si increases the Si and P concentration, the C and N efficiency, the C:N ratio, and the dry mass production. However, it decreases the C and N concentration and the C:P, C:Si, and N:P ratios in sugarcane leaves and stems regardless of the water regime adopted in the three tropical soils. Cluster and principal components analysis indicated that the intensity of the beneficial effects of Si fertigation on sugarcane plants varies depending on the cultivation soil and water conditions. We found that Si can be used in sugarcane with and without water stress. It changes the C:N:P homeostasis enough to improve the nutritional efficiency of C, P, N, and, consequently, the dry mass accumulation on the stems, with variation in the different cultivated soils.

“…Moreover, there were doubts regarding the feasibility of soluble Si application via solution (fertigation or foliar spraying) to eld-grown sugarcane in increasing the crop's Si uptake. It occurs because the studies in this condition were carried out with Si sources (calcium silicate) with very low water solubility, besides the use of relatively high doses, which were incorporated into the soil in total area (up to 600 kg ha − 1 of Si) 22 , or in planting furrows (55 up to 165 kg ha − 1 of Si) 18,19 .…”

Adopting a Si supply strategy can amplify sugarcane response. Thus, this study aimed to verify whether Si supply in the pre-sprouted seedling (PSS) formation phase would have an effect after field transplanting similar to Si supply only in the field phase (via foliar spraying or fertigation), and whether Si supply in the PSS formation phase associated with Si fertigation after transplanting can potentiate or amplify Si benefits. Two experiments were conducted. In experiment I, PSS were grown in nursery without Si (Control) and with Si. Experiment II was conducted in the field on Eutrustox with the following treatments: no Si supply (Control); Si supplied during the PSS formation phase; Si supplied through foliar spraying in the field; Si supplied through fertigation in the field; and Si supplied in the PSS formation phase and during field development. Silicon use in both crop phases benefited sugarcane by increasing photosynthetic pigment content and the antioxidative defense system. The innovation of Si management to be supplied via fertigation integrated in both crop phases (PSS and in the field) optimizes the element use by increasing the crop's productivity and sustainability.
