The influence of Atonik SL, Betokson Super 050 SL and InsolCa on yielding of strawberry (Fragaria x ananassa Duch.) cv. ‘Senga Sengana’ and ‘Kent’

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.
