The effects of foliar amino acid and Zn applications on agronomic traits and Zn biofortification in soybean (Glycine max L.).

This article, published in Frontiers in Plant Science, explores the effects of foliar amino acid and zinc applications on agronomic traits and zinc biofortification in soybeans. The study found that the application of amino acids and zinc did not affect the yield of soybeans, but certain combinations did impact the number of pods and branches. Additionally, amino acid application had a significant effect on nitrogen and protein content in the grains. The most effective treatment for enhancing zinc biofortification in soybean grains was the application of a specific combination of amino acids and zinc. Overall, the study highlights the potential for foliar application of amino acids and zinc to enhance zinc accumulation in soybean grains. [Extracted from the article]
