The effect of growth regulator application and bud removal on yield was studied over 2 years in faba bean variety Herz-Freya. Growth regulators were sprayed in the field and extractable phytohormone contents determined for various plant parts. Plants were also decapitated and whole inflorescences or only the oldest buds were removed to remove possible dominance effects. Yields from treated plants were generally similar to control plants, except for GA3 treatment at the sixth leaf stage in the first trial year which significantly increased yield. Removal of the two proximal buds of every inflorescence reduced fruit drop and number of flowers. The course of hormone contents corresponded to fruit development but this cannot be related to yield components
