Vermicompost and worm-bed leachate (WBL) are two products obtained from vermicomposting. The objective of this study was to evaluate the effect of different combinations of vermicompost and WBL on cultivating radish (Raphanus sativus L.). A multilevel factorial design with 25 treatments was used to investigate the effect of vermicompost at 0, 10, 20, 30, or 40% and WBL at 0, 10, 20, 30, or 40% on germination and growth parameters. A maximum seed germination of 54%, number of leaves (2.8), and plant height (8.6 cm) were obtained with 10% vermicompost and 10% WBL. A maximum shoot (7.0 g) and root (7.3 g) dry weight was obtained with 10% vermicompost and 15% WBL. Vermicompost and worm-bed leachate have an inhibitory effect at higher concentrations on seed germination and plant growth. These inhibitory effects might be due to increased salt concentrations, pH or auxin-like effects of humic and fulvic acids.
