The aim of this study is to provide a broad overview of the effects of biostimulants belonging to the above-mentioned groups. These effects include plant growth and yield, improved nutrition, influence on the content of bioactive components, and protection against stress and bacterial and fungal pathogens. The use of biostimulants is an important element of modern horticultural plant cultivation, which aims to improve plant growth, yield and quality while reducing the use of chemicals.
