Popis:	Composting and land application of municipal sewage sludge (SS) and yard waste (YW) compost are increasingly popular ways for using organic waste as a source of organic matter, while decreasing the amount of waste being diverted into landfills. Researchers have largely ignored the effect of SS and SS mixed with YW (SS+YW) compost on the antioxidant contents of vegetables grown under this practice. Accordingly, the main objective of this investigation was to monitor the impact of SS and SS+YW on the nutritional composition of pepper and melon fruits at harvest. Total phenols and ascorbic acid contents of pepper and melons (determined by the Folin-Ciocalteau and the dichlorophenol–indophenol methods, respectively) were greater in pepper than melon fruits. Soil amended with SS or SS+YW significantly elevated the concentrations of ascorbic acid and total phenols in melon fruits compared to no-mulch native soil. The application of SS did not modify the concentration of β-carotene in melon fruits at three harve...
