The application of fenugreek extracts to sunflowers increased energy for higher yield.

In recent decades, the use of biostimulants has increased with the aim of creating an alternative to the use of chemical fertilizers and achieving sustainable agriculture. In a new study, sunflower plants were grown under controlled conditions, and four extracts of fenugreek, rich in trigonelline, were applied as green biostimulants through root and foliar fertilization. Plant-derived biostimulants are one of the types of biostimulants that are currently of great interest both in research and in the agri-food industry. They can be defined as natural products obtained from different parts of plants, such as seeds, roots, or leaves. They contain antioxidant compounds such as glutathione and ascorbate, essential nutrients, vitamins, essential amino acids and peptides, beneficial elements, and, in some cases, bioactive compounds. The main species from which extracts are obtained for use as green biostimulants are alfalfa, moringa, aloe vera, and nettle. These extracts can be applied ...
