Relevance. Foliar feeding when growing vegetables is due to its positive effect on quality and yield indicators. The use of microfertilizers for foliar feeding allows optimizing the absorption of nutrients by plants, which can not only reduce economic costs, but also regulate the accumulation of biologically active substances. Identifying the optimal fertilizing system for different varieties and hybrids of vegetables is especially important in risky farming areas, where the main factor regulating yield indicators is weather.Methodology. The purpose of the work is to conduct a comparative assessment of the effectiveness of foliar feeding of the white cabbage variety Zimovka 1474 different agrochemicals. In a field experiment for three years (2018-2020), the effect of microfertilizers, humate, chelates and a biostimulator on the yield, biochemical and microelement composition of white cabbage variety Zimovka 1434 was studied.Results. It has been shown that the biometric characteristics of cabbage are best influenced by foliar fertilization with microfertilizer Aquarin and the biostimulator BIS-65, and the total and marketable yield is influenced by microfertilizer in chelate form Helaton. The greatest accumulation of dry matter, sugars, and vitamin C was typical for variants using the biological product BIS-65 and chelated fertilizers (Tiaton, Helaton). Chelated fertilizers also contributed to an increase in the accumulation of elements such as potassium, calcium, iron, zinc and manganese in cabbage heads.
