Determination of the impact of biostimulants on the content and uptake of sodium and aluminum in two varieties of Jerusalem artichoke

Jerusalem artichoke tubers are characterized by their high nutritional value and are influenced by various factors, e.g., variety, biostimulant application, and environmental conditions.The aim of the three-year (2021-2023) study was to determine the sodium and aluminum contents and uptake in two Jerusalem artichoke varieties, under the influence of biostimulants B1 (Kaishi), B2 (Maral), B3 (Nutrigreen AD), and B4 (Vanadoo).Elemental analysis was performed using Inductively Coupled Plasma-Optical Emission Spectrometry.The results showed that both varieties had comparable sodium and aluminum contents.Biostimulant B2 increased the sodium content compared to the control variant, while reducing the aluminum content.Furthermore, the variety Albik exhibited higher sodium uptake and lower aluminum uptake than Rubik.Notably, B2 enhanced the sodium uptake in Albik, whereas B4 was most effective for Rubik.Aluminum uptake decreased in the Albik variety with biostimulant B3, while all biostimulants raised the aluminum uptake in Rubik.The study indicates that biostimulants may beneficially influence the sodium and aluminum content and uptake in Jerusalem artichoke tubers, highlighting the need for further research.
