The in uence of different fertilizer sources on head cabbage (Brassica oleracea var. capitata, cv. , Pructor ,) yield and quality was studied. The eld experiment was carried out on alluvial-meadow soil ( uvisol-FAO) pH 6.5. The trial included mineral fertilizer, farmyard manure and foliar fertilizer. The highest yield values were obtained with mineral fertilization. The best quality parameters in the cabbage leaves-dry weight, total soluble sugars, cellulose, vitamin C and nitrates content were obtained in the treatments with foliar fertilization followed by the treatments with organic fertilization. The observed decrease of N and K residuals after the harvest of head cabbage crop in comparison with the initial soil reserves indicated complete absorption of fertilizers supplied and this is a very important result from ecological point of view.
