Beneficial effects of silicon fertilizers on indicators of seed germination, grain yield of barley and soybean and silage corn biomass

The aim of the study was to determine optimal doses and methods application silicon fertilizer in barley, silage corn, soybean under climatic conditions Ukraine. A series laboratory field experiments were carried out, as along with statistical analytic data processing. small-plot experiment conducted on chernozem podzolic soil at NSC ?Institute for Soil Science Agrochemistry Research named after O.N. Sokolovsky? (Kharkiv region, Forest-Steppe Ukraine). set up Petri dishes using a preparative form different concentrations (0%, 0.5%, 0.75% 1.0%) potassium silicate their assessment germination indicators barley corn seeds. significant stimulating effect capacity energy seeds shown, concentration solution pre-sowing seed treatment established. high positive correlation determined between amount SiO2 yield studied crops (P < 0.01; R = 0,7479-0,8682). levels into established obtain maximum crop yields (105 kg ha-1 92 SiO2ha-1 76 soybean). Also, each crops, most fertilizers determined, which will improve productivity soils.
