INFLUENCE OF BIOPRODUCTS ON THE YIELD OF CORN HYBRIDS

In the conditions of the Southern Steppe of Ukraine, the yield of corn grain depends on the weather conditions of the year of the study, as well as variants of the experiment. Thus, in the more favorable weather conditions in 2023, the yield of corn, on average, according to the experiment, was 8.3 t/ha, which exceeded the indicators of adverse, sharply drying 2024 by 1.4 t/ha or by 16.9%. Biological products were important in the formation of corn grain yields, regardless of the year. With pre-sowing seed treatment with a biological products organic-balance and carrying out twice for the growing season of foliar feeding of corn plants with azotophyte-r, a higher grain yield was formed, especially for growing Grand 6 hybrid.
