Abstract. The present research was carried out to investigate the effects of some macro and micronutrients on fruit
quality and quantity in barberry (Berberis vulgaris L.) plants. Treatments included manganese (Mn 20 and 40 mg･L-1),
potassium (K 1 and 2%), calcium (Ca 2 and 3%), boron (B 1000 and B 2000 mg･L-1), zinc (Zn 300 and 600 mg･L-1)
and water (W). The highest and lowest yields were obtained by W and Ca 2%, respectively. Moreover, the highest and
lowest fruit numbers resulted from B 2000 mg･L-1 and Ca 2% treatments, respectively. Although high amount of
vitamin C was resulted from Ca treatments, high concentration of TA and SSC were found in K treatments. The results
of these studies showed that mineral nutrients via spray can alter the yield and quality of barberry fruits.
