| Abstract | The purpose of the research was to determine the effect of the new BioSpectrum biological preparation on the yield of corn under different doses of mineral fertilizers. The research was carried out in the conditions of a long-term experiment of the department of agrochemistry and soil science of the Uman National University on podzolized heavy loam chernozem, which was laid in 1964. Corn was grown according to the generally recognized technology for the conditions of the Right Bank Forest Steppe. The meteorological conditions in the Right Bank Forest Steppe for 2020–2021 were analyzed and their compliance with the biological needs of growing the mid-ripening corn hybrid DKS 3511 was determined. The influence of weather conditions, mineral fertilizers, and BioSpectrum biostimulator on its productivity was determined. On average, over the years of research, the productivity of the mid-ripening hybrid DKS 3511 was the highest and amounted to 9,75 t/ha when mineral fertilizers were applied with a dose of N135P135K135. With the combined use of mineral fertilizers and BioSpectrum biostimulator, it varied depending on the doses of fertilizers from 8,02–10,61 t/ha. The use of only the BioSpectrum drug against the background of single, double and triple doses of fertilizers provided an increase in yield at the level of 0,32–0,86 t/ha. It was established that the share of influence of mineral fertilizers in the formation of crop growth was 14–35%. With the combined use of BioSpectrum biological preparation and mineral fertilizers, this indicator varied from 17 to 37 %, and the share of influence of BioSpectrum biological preparation in the formation of crop growth against a natural background and when applied against the background of different doses of mineral fertilizers varied in the range of 3–9 %. | ||
