Analysis of interactions between foliar fertilizers and chemical composition of sunflower leaf apparatus

The purpose of the work is to use the analysis of sunflower foliage as a diagnostic tool for the accumulation of trace elements from the use of foliar top dressing "Revitaplant Sunflower". These studies were conducted in 2021-2022 at the experimental field of I. A. Bunin YSU in the Lipetsk region. Sowing was carried out on plots with three repetitions and two variants:control (without micro-fertilization treatment) and Revitaplant Sunflower 2 l/ha. The treatment was carried out in the vegetation phase of 6-8 leaves of the culture. The use of "Revitaplant Sunflower" on sunflower culture positively affected the chemical composition in the leaves of sunflower plants. The analysis showed a high response of sunflower to the assimilation of iron and manganese and optimal for copper and zinc.
