In an experiment carried out in 2006-2007, influence of different fertilizers on yieldand quality of cv. Kent strawberry fruit was determined. Two combinations were tested,each consisting of 3 types of fertilizers. The control plants remained unfertilized. In bothcombinations, two types of multi-component fertilizers were used (T – 5% N, 5% P2O5,15% K2O and O – 10% N, 5% P2O5, 10% K2O) as well as one rate of ammonium nitrate toprovide 50 kg N ha–1 in the first combination and 70 kg N ha–1 in the second one. Theusage of multi-component fertilizers, especially O type resulted in an increase of cv. Kent strawberry yield. The fruit collected from the control plants and the ones fertilized withammonium nitrate weighed less than berries obtained from plants fertilized with multicomponentfertilizers. The treatment with multi-component fertilizers enhanced firmnessas well as calcium, phosphorus and potassium content in fruit. The berries fertilized withhigher rate of T fertilizer contained more soluble solids, total sugar and reducing sugar.Neither the type of fertilizers, nor their rate affected acidity, vitamin C, total phenol andmagnesium content in berries. Higher antioxidant activity towards DPPH radicals was observedin fruit obtained from plants fertilized with lower and higher rate of ammoniumnitrate. The lowest nitrogen content was observed for control berries. Practically, the differencesregarding nitrogen content between the fruits of the first (50 kg N ha–1) and secondcombination (70 kg N ha–1) were negligible.
