The results of three-year studies (2020-2022) on the effectiveness of the use of various growth regulators in the cultivation of corn hybrids for grain in the forest-steppe zone of Western Siberia are presented. The studies were carried out on leached chernozem of the Novosibirsk region of the Novosibirsk region and on gray forest soil of the forest-steppe zone of the Novosibirsk Ob region. It is shown that in the forest-steppe of Western Siberia it is effective to use modern innovative growth regulators and chelate fertilizers in the process of corn grain production. It has been shown that on soil types it is effective to apply growth regulators Ecofus 0.001%, Epin-Extra 0.04% l/ha and chelated organosilicon fertilizer Siliplant 0.01% with a working solution flow rate of 300 l/ha in the phase of four to six maize leaves on six hybrids. It was statistically determined that the yield of corn grain depended on the element of technology by 33, genotype - 27 and the conditions of the year 23% and green mass, respectively, 35, 29 and 25%. It was shown that growth regulators and chelate fertilizers improved the parameters of the yield structure of corn hybrids.
