Abstract: Evaluation was performed of the effect made by integrated and conventional production systems on phenolic composition and antioxidant capacity of cv. Senga Sengana strawberry grown under greenhouse conditions over two consecutive years. The experiment also involved three different types of fertilizer. The integrated production system provides significantly larger quantities of polyphenols as well as a higher antioxidant capacity, compared to values obtained using the conventional system. The investigation into total phenolics content and total antioxidant capacity, as well as individual flavonols and phenolic acids (except gallic acid) content reveals a pronounced effect of the applied biofertilizers (PGPR 1 and PGPR 2). On the other hand, applied chemical fertilizer (Multi KMg) gives the best results in terms of anthocyanins content. These results indicate that there were significant differences in phenols content among integrated and conventional production systems, as well as between biofertilizers and a chemical fertilizer.
