Under conditions of fulfillment of the basic requirements of organic production, there is a threat of crop loss, auxiliary products can be used, if they are allowed for use in organic production. These are substances listed in Annex II of Regulation (EU) No. 889/2008) and/or ready-made commercial forms (auxiliary products) approved by the certification body.Therefore, the main goal of our research was to determine the most effective auxiliary products in organic production for growing corn for grain.The research was conducted in 2019-2022 on the basis of the Training Production Center (TPC) of the Bila Tserkva National Agrarian University (BNAU).The soil under the test is typical chernozem. Agrochemical characteristics of the soil: humus (according to the Tyurin and Kononova method) -3.4%, easily hydrolyzed nitrogen (according to the Kornfield method) -110, mobile compounds of phosphorus and potassium (according to the Chirikov method) -120 and 110 mg/kg of soil, respectively. The studied hybrid Ostrech SV. The scheme of the experiment provides: No treatment (control) Spraying during the growing season (starting with 3 leaves three times during the growing season with an interval of 10-12 SE "Avatar organic"); Intensive technology" Intensive technology + "Avatar organic". The product "Avatar Organic" contains micro-and ultra-microelements necessary for plants that are part of the microelement complex in the form of nanoparticles chelated with natural organic acids -citric, succinic, malic, tartaric and their mixtures. This auxiliary product is included in the List of pesticides and agrochemicals allowed for use in Ukraine, as well as in the List of auxiliary products for use in organic production, taking into account the requirements of the standard of international accredited certification bodies for organic production and processing, which is equivalent to EU regulations No. 834/2007 and No. 889/2008. So, as a result of the research conducted in 2019-2022, the yield of corn per grain in the control variants was at the level of 5.9 t/ha. The use of auxiliary product "Avatar organic" helped to increase the crop yield to 6.20 t/ha. With the use of intensive corn cultivation technology, the yield level was fixed at 8.32 t/ha. With the use of "Avatar Organic" in this technology, the yield level increased to 8.65 t/ha. It should be noted the positive effect of the auxiliary product "Avatar Organic" for conducting organic production, where the average yield level for 2019-2022 increased by 0.30 t/ha, compared to the control variants.
