Efficiency of using silicon dioxide nanoparticles to increase wheat productivity in soil and climatic conditions of Western Siberia
In this study, we investigated the effectiveness of silica nanoparticle (SiO2NP) suspension for pre-sowing inoculation of spring wheat seeds under soil and climatic conditions of the Western Siberia. We report that SiO2NP suspension at concentrations of 3 × 10−7% to 3 × 10−4% does not have a toxic e...

| Итог: | In this study, we investigated the effectiveness of silica nanoparticle (SiO2NP) suspension for pre-sowing inoculation of spring wheat seeds under soil and climatic conditions of the Western Siberia. We report that SiO2NP suspension at concentrations of 3 × 10−7% to 3 × 10−4% does not have a toxic effect on the culture of microalgae Chlorella vulgaris and spring wheat. On the contrary, seed inoculation with nanoparticles increased seed germination by 15-40% relative to the control. The green mass yield of wheat seedlings exposed to SiO2NPs also increased by 5-41% relative to the control. In field experiments, presowing treatment of spring wheat with SiO2NPs at concentrations of 3.0 × 10−4%, 1.5 × 10−4%, and 0.3 × 10−4% increased the main morphometric parameters of plants, such as height and green mass. Seed inoculation with SiO2NPs improved plant productivity: the grain yield in the variant with the minimum (0.3 × 10−4%) and average (1.5 × 10−4%) concentrations of SiO2NPs grew by 20.1% and 18.4%, respectively. Plants inoculated with SiO2NPs showed higher resistance to root rot pathogens (Fusarium oxysporum and Bipolaris sorokiniana): the disease prevalence decreased by 16-33% and the disease incidence index grew by 7-14% relative to the control. Seed inoculation with SiO2NPs increased the content of protein and important biogenic elements such as potassium, calcium, sulfur, phosphorus, and silicon in the grain. |
