The effect of the foliar fertilizer Campofort Special-Zn (CSZn) and the plant growth regulator Rastim 30 DKV (RM) on growth, yield parameters and seed protein content was studied in mung bean [ <i>Vigna radiata</i> (L.) Wilczek] plants grown under greenhouse and field conditions. CSZn at a dose of 10 l per ha, and RM at doses of 3, 30 and 60 g per ha were applied alone or in combination (before flowering and 14 days after first application). The initiation of flowering and ripening processes and the chlorophyll content Chl (<i>a</i> + <i>b</i>) were evaluated. At harvest, total yield and yield components (number of pods per plant, seed number per pod, single pod mass, seed mass per pod), germination of seeds and seed protein content were determined. RM applied alone induced intensive flowering, increased the number of pods and yield components per plant, accelerated the ripening of the pods, increased the Chl content in the leaves and delayed senescence in treated plants. The mixture of RM with CSZn (60 g + 10 l per ha) and RM alone at a dose of 60 g per ha had a retarding and morphogenic effect on the growth of treated plants and also decreased the protein content and germination of the seeds. The best results for all studied parameters were achieved in the field at a dose of 30 g RM + 10 l CSZn and under greenhouse conditions at a dose of 3 g RM + 10 l CSZn.
