Improving abiotic stress tolerance of soybean genotypes

Abstract

The purpose of this study is to examine whether foliar nutrient treatments can improve the abiotic stress tolerance of genotypes of soybean (Glycine max L.) grown in Hungary under drought-prone and non-irrigated conditions. The research focuses on assessing the effects of foliar applications of selenium (Se), silicon (Si), and sulfur (S) – individually and in combination – on key morphophysiological and yield parameters of different soybean genotypes. In 2022, four varieties (Ananda, Suraja, Yakari and Pocahontas) were tested under Se, Si and Se + Si treatments, whereas in 2023, the varieties (Paula, Suraja, Yakari and Pocahontas) were treated with Se 2.5mg m-2, Optysil, S, and Novosil.
