“…Similarly, Silva et al (2012) reported that Si resulted in an increase in the chlorophyll level of two tomato cultivars (Lycopersicon esculentum L.). Xie et al (2014) applied 750 kg ha -1 of silicate and also observed chlorophyll levels 20 % higher in maize plants. In a study made by Hattori et al (2005), a marked Si-induced enhancement in photosynthesis and chlorophyll fluorescence was reported in sorghum plants [Sorghum bicolor (L.) Moench], under water deficit conditions.…”

“…Calcium and magnesium silicate can be used as a corrective of soil acidity (Castro & Crusciol 2015, Sarto et al 2015 and as a Si source (Ruppenthal et al 2016). The application of Si shows beneficial effects on the growth and yield of several crops, especially those considered as Si-accumulating plants, such as rice, sugarcane, maize, sorghum and wheat (Hattori et al 2005, Kaya et al 2006, Zanão-Júnior et al 2010, Sarto et al 2015, Camargo et al 2017. However, dicotyledonous species, considered as non-Si accumulating plants, such as tomato, cucumber, cowpea, cotton, potato and soybean, have also responded positively to the soil-applied Si (Nelwamondo & Dakora 1999, Toresano-Sánchez et al 2012, Ferraz et al 2014, Pilon et al 2014, Wang et al 2015, Pascual et al 2016.…”

The application of silicon (Si) to the soil can increase the grain yield of the soybean crop by improving the nitrogen biological fixation, due to its beneficial effect on the Bradyrhizobium-soybean symbiosis. This study aimed to investigate the effect of fertilization with calcium and magnesium silicate on plant growth, root nodulation and nitrogen (N) uptake, in two soybean cultivars [BRS 1074 IPRO (transgenic) and BRS-MG 800A (conventional)], under greenhouse conditions. The application of silicate significantly increased the number of root nodules only for the BRS-MG 800A, while the positive effects of the silicate addition on nodule size, chlorophyll level and leaf N concentration were observed in both cultivars. The soybean cultivars show distinct responses to the silicate application, with respect to growth and dry matter yield, being the BRS 1074 IPRO more responsive than the BRS-MG 800A. Therefore, Si may induce the formation of root nodules in soybean plants and lead to significant increases in the nitrogen biological fixation and plant growth. These results highlight that Si is not only involved in the improvement of plant growth, but it can be also considered a crucial element to improve the symbiotic performance of soybean plants. However, the physiological basis of how and where silicate exerts its influence on nodulation and nitrogen biological fixation still remains unknown.

“…noticed in environmental conditions without stress (Tamai and Ma, 2008). Similarly, maize plants evaluated in a stress-free field conditions obtained an increase in the photosynthetic rate and stomatal conductance, nevertherless, a decrease in transpiration rate and internal carbon concentration in the leaf substomatal chamber (Xie et al, 2014). We found studies that report Si positive effects occurred in stressful field conditions to the plants, for example, salt stress, drought stress, nutrient imbalance, presence of heavy metal (Ali et al, 2013) and inoculation of the pathogenic fungus (Polanco et al, 2014;Etesami, 2018).…”

“…The Si physiological effects under photosynthetic performance using maize plants in early phenological growth stages are not elucidated in the literature, but it can be stated that the Si uptake is sufficient to trigger biochemical effects in photosynthetic processes. In addition, we can speculate that the shoot application of Si from potassium silicate (K 2 SiO 3 ), has allowed the biopolymers formations, which would impair Si uptake by the leaves (Xie et al, 2014).…”

Green maize (Zea mays L.) is a cultivated species of significant importance in the agricultural scene. The literature reports that Si has been used as an alternative option for sustainable agricultural systems. We examined the hypothesis that this beneficial element will improve the photosynthetic performance and biological productivity of crop plants, under field conditions, without nutritional stress. In this context, leaf gas exchanges, physiological indexes, and growth parameters were investigated in green maize, AG4051 and CATIVERDE 02, under Si availabilities at the initial stage of vegetative development. The treatments were: Via shoot; 0, 130, 260, 390 and 520 g ha -1 ; and via roots; 0, 100, 500, 1000 and 2000 kg ha -1 . The experimental design was randomized blocks (RB) with 5 blocks (experimental plots). The beneficial mineral element Si did not have an improvement on gas exchanges of green maize plants and, consequently, plant development. In conclusion, we reject our initial hypothesis and we accepted the alternative hypothesis, that the beneficial element Si did not optimize the photosynthetic performance and biological productivity of green maize plants, without nutritional stress.

“…This increase in yield was related to the increase in plant chlorophyll content and number of chloroplasts upon silicate fertilization, which improved the photosynthetic efficiency and reduced the transpiration rate, thus avoiding water loss through the stomata. These changes may also alter the architecture of the plants, rendering them more upright and thus reducing self-shading (Ma & Takahashi, 2002;Xie et al, 2014) …”

The fall armyworm (Spodoptera frugiperda) is an important pest of corn in Brazil. Insecticides are applied to reduce the losses caused by this pest. Integrated control methods, including resistance induction in plants using silicon and transgenic hybrids, must be used to reduce the impacts caused by insecticide application. The aim of this study was to assess the effects of calcium silicate application (CaSi 4 ) to the sowing furrow on S. frugiperda damage to and incidence on conventional and transgenic genotypes with different Bt technologies. The treatments were arranged in a randomized block design in a 3x4x4 factorial scheme with three corn hybrids, Morgan 30A91 PRO Power Core ® (Cry1F, Cry1A105, Cry2Ab2 Bt toxin), Morgan 20A55 Herculex ® (Cry1F Bt toxin) and AG 1051 (conventional); four silicon doses, 0, 300, 600 and 900 kg. ha -1 calcium and magnesium silicate (Agrosilicio Plus ® , Ca = 25%, Mg = 6%, Si = 10.5%); and four assessment times, 15, 30, 45 and 60 days after emergence (DAE). Four replicates were performed. The mean number of caterpillars per plant, damage caused by S. frugiperda, and production components were assessed. Calcium and magnesium silicate application induced resistance in corn plants, thus reducing the damage caused by S. frugiperda. Corn responded to resistance induction with increasing doses of calcium and magnesium silicate. The transgenic hybrid with three proteins (Morgan 30A91 PRO) improved protection against S. frugiperda. The interaction between silicate fertilization and transgenics produced a synergistic effect, suggesting a viable alternative for S. frugiperda control.
