EFFECT OF NANO-SILICON ON SPRING WHEAT PHYTOSYNTHETIC PRODUCTIVITY
The research results indicate that the use of “Nano-Si” product exerts effect on wheat plants by extended photosynthetic work providing highest level of solar energy absorption by vegetation cover. This paper presents the results of Orlovskiy Regional Center of Agricultural Biotechnology at the Orel State Agricultural University on the effect of the product “Nano-Si” on the photosynthetic potential of wheat variety Darya. The research goal was to study the silicon product's influence on photosynthetic efficiency of spring wheat plants. The research target was a promising wheat variety Darya. The phenological observations and “Nano-Si” impact on photosynthetic efficiency were conducted in field experiments. The area of wheat leaves treated with “Nano-Si” was measured by Reshetskiy's method. It was found that the use of “Nano-Si” contributes to increased leaf area index of spring wheat. The productivity of spring wheat crops was calculated in this study. It is found that the use of “Nano-Si” increases tilling capacity 2.5 times, thus promoting increase in productivity and coefficient of economic efficiency. Dry biomass gain per 1 plant at booting stage with “Nano-Si” treatment made 1.5 g - twice as much as that in the control. Ash percentage in plants which were treated with “Nano-Si” during the growing season increased by 15.4% as compared to the control; that showed faster absorption of mineral elements by the root system of the experimental plants. When “Nano-Si” is used during pre-sowing treatment and was double sprayed on plants during growing season, this increased plant height, area of leaves, tillering node capacity, photosynthetic potential and productivity; the absorption of minerals by the root system also increased.
