Abstract

The paper presents the results of trials of silicon-containing preparations ADK (amorphous silicon dioxide) and Risilika (pyrolysate of rice husks and straw) as fertilizers for sugar beet in field experiments. The experimental design included seven options: 1. Control; 2^nd , 3^rd and 4^th options with the application of ADK into the soil at doses of 100, 250, 500 kg / ha; 5^th ,6^th and 7^th options - Risilika in appropriate doses. Both preparations had a positive effect on the nutrient regime of the soil (the content of available compounds of nitrogen, phosphorus, potassium and silicon), yield and quality of sugar beet roots. The yield of roots when using ADK as a fertilizer increased by 3.32-6.52 t/ha (14-27%), Risilika - by 1.92-4.75 t/ha (8-19%). The yield increases as a result of raising preparation doses. At the same time, the increase in sugar content provided an additional yield of more than 1 ton of sugar per hectare.
