The results showed that L-tryptophan and beta-indodylacetic acid had a small effect on the modification of chemical composition of seeds, pods, stems and leaves of horse bean. The precursors of cytokinins and benzyladenine had a positive effect on the concentration of phosphorus in seed, but produced a negative influence on the content of nitrogen in pods, phosphorus in pods and leaves and calcium in stems. L-methionine increased the content of nitrogen in pods, nitrogen and phosphorus in stems and potassium calcium and magnesium in leaves. The introduction of Azotobacter into soil stimulated the activity of precursors of ethylene, producing in effect a higher content of potassium in vegetative organs of horse bean, phosphorus in seeds and calcium in leaves
