In an experiment carried out in 2006-2007, influence of different fertilizers on yield and 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 both combinations, 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 to provide 50 kg N ha–1 in the first combination and 70 kg N ha–1 in the second one. The usage 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 with ammonium nitrate weighed less than berries obtained from plants fertilized with multicomponent fertilizers. The treatment with multi-component fertilizers enhanced firmness as well as calcium, phosphorus and potassium content in fruit. The berries fertilized with higher 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 and magnesium content in berries. Higher antioxidant activity towards DPPH radicals was observed in fruit obtained from plants fertilized with lower and higher rate of ammonium nitrate. The lowest nitrogen content was observed for control berries. Practically, the differences regarding nitrogen content between the fruits of the first (50 kg N ha–1) and second combination (70 kg N ha–1) were negligible.

The study involved three strawberry cultivars: 'Senga Sengana', 'Kent' and 'El- santa', planted in the spring of 2003 in a row system in the Pomological Orchard of RIPF in Skierniewice, Poland. The experiment was carried out in 2006 on 4-year-old plants as a continuation of the project Cost 631. The strawberry plants were mulched with a peat substrate, or sawdust, or pine bark, or compost or rye straw, and inoculated with a mycorrhizal preparation Mycosat. The mulches were replenished every year in the same amount during the flowering of the plants. The results of the experiments indicate that the combinations used did not, in general, cause a significant change in the yielding of plants during the experimental period presented. An exception were the plants of the cultivar 'Kent' mulched with straw, which produced a significantly lower yield, by 18.4% on average, in comparison with the control plants or those mulched with bark. Plants of the cultivar 'Elsanta' mulched with compost or sawdust were characterized by a significantly greater mean fruit weight (by an average of 1.5 g) compared with the control. On the whole, the use of the mulches and the mycorrhizal product contributed to an increase in the number of fruits of the class 'Ekstra'. Significant differences were found on the plots of 'Senga Sengana' mulched with straw or inoculated with the mycorrhizal substrate, from which, on the average, 71% more class 'Ekstra' berries were collected than from the control plants (non- mulched). The experiments confirmed the cultivar-specific differences in yield between the strawberry cultivars studied. At comparable yields, they differed significantly in terms of the number and mean weight of the fruits collected.

The chemical composition of strawberry fruit depends mainly on cultivar, fruit maturity degree and climatic conditions in the growing period. Fruit quality is also determined by a cultivation technology. The influence of two biostimulants (Atonik SL and Betokson Super 050 SL), which were used separately, in combination with each other or with the liquid fertilizer InsolCa, on yielding and fruit quality of two strawberry cultivars: ‘Senga Sengana’ and ‘Kent’, was tested. Betokson Super 050 SL + InsolCa tended to improve the yield of both cultivars. Significant differences compared to the control were evident especially in 2001. Fruits of ‘Senga Sengana’ started ripening later and had more ascorbic acid, anthocyanins and acidity than ‘Kent’. The use of Betokson Super 050 SL + InsolCa improved the content of ascorbic acid, anthocyanins and sugar as well as acidity in strawberries of both cultivars. The use of Betokson Super 050 SL + Atonik SL significantly increased the content of ascorbic acid and sugar in fruits of both cultivars. ‘Kent’ strawberries also responded to the treatment with an increase in anthocyanin content and acidity.
