AB  - The aim of this research was to examine the effect of fertilizer
treatment on the content of polyphenols in velvetleaf and maize, grown without use of
herbicides under controlled conditions (12h/12h, T 25º/22ºC day/night). Plants were
treated with organic - F1 and synthetic fertilizers - F2 and F3. The content of total
phenols, individual polyphenolic acids and antioxidant activity of plant extracts were
examined, as important indicators of the plant condition and its resistance to oxidative
stress. The content of total phenols was determined spectrophotometrically (modified
Folin-Ciocalteu method). The content of individual polyphenolic acids was
determined by the high-performance liquid chromatography method, while
measurement of polyphenols antioxidant activity was determined by the DPPH
method. It was established that in maize, the application of fertilizers, neither in
monoculture nor in competition with velvetleaf plants, caused statistically significant
changes in the content of polyphenolic acids. However, in velvetleaf, the use of
fertilizers led to an increase in the content of polyphenolic acids in conditions of
competition vs monoculture. The content of chlorogenic, p-coumaric and trans-ferulic
acids was statistically, significantly higher in plants of velvetleaf competition vs
monoculture, and the content of chlorogenic, p-coumaric and cinnamic acids was
lower in plants of maize competition vs monoculture. A statistically significant
increase in the content of total polyphenols and their antioxidant activity in velvetleaf
plants indicates the difficulty of removing weeds from crops, especially resistant
populations. The research conducted and the results obtained confirm that weeds in
competitive conditions manifest their natural competitive advantage, which is further
enhanced by crop feeding.
