Silicon in agrocenosis with spring wheat

Abstract

The influence of various ways of using silicon in the form of potassium silicate on the yield of spring wheat under the conditions of model agrocenosis has been studied. To address the issues raised, a vegetative experiment was carried out in the soil culture. Studied two ways of making potassium silicate by treating seeds before sowing and applying to the soil. The positive effect of the silicon-containing compound was established both on the mass of grain and on the mass of straw. The greatest efficiency of silicon was manifested when using potassium silicate for seed treatment before sowing. The mass of grain increased as a result of an increase in the average number of seeds per ear by 5% and the weight of 1000 grains by 22%. An increase in the removal of basic nutrients from the soil was revealed as a result of an increase in the content of nitrogen, phosphorus and potassium and stimulation of the processes of their outflow from vegetative organs to generative organs.
