The studies were carried out in 2020-2022 in the piedmont zone of the Kabardino-Balkarian Republic on the “Cherek-Kolos” LLC lands. The soil is leached, medium-thick, slightly humus heavy loamy chernozem on carbonate clays. In an experiment to study the effectiveness of the macro-microelements foliar application in different forms on soybean culture, three factors were studied: varieties SK Veda – early-ripening, Rubin – mid-ripening (factor A); treatment of vegetative plants with liquid mineral fertilizers (factor B); processing time (factor C). The maximum values of soybean yield regardless of the variety were achieved when vegetative soybean plants were treated with the nutrient deficiency corrector Polidon Bor. Maximum productivity is achieved when soybean plants are treated in the primordial leaf phase.
