Studies to substantiate the species and timing of use of silicon-containing preparations providing the highest productivity of the early ripening hybrid of corn were carried out on heavy loamy leached chernozem. Non-root treatment with NanoSilicon, contributed to an increase in the number of grains in the cob by 13.6-26.7% compared with the control (water treatment), and it was more effective to use the drug in a phase of seven to eight leaves and double treatment. When using Kelik Potassium-Silicon and Microvit-6 Silicon, the number of grains increased by 10.0-19.3%. Double processing with NanoSilicon additionally produced 16.2 g of grain from the ear, which is 28.4% more than in the control. During non-root treatment, Kelik Potassium-Silicon and Microvit-6 Silicon growth compared to the control was 23.3-26.7%. Against the background of foliar treatment with drugs, grain yield increased by 37.5-39.3%, and the best anti-stress effect was achieved by double treatment with NanoSilicon and the use of MicroVit-6 Silicon in the phase of five leaves.
