Popis: The efficiency of the distillery sludge-based vermicompost to enhance the growth of Raphanus sativus (radish) was tested with distillery sludge-based compost (DSC) and vermicompost (DSV), vegetable waste vermicompost (VV), and commercially available chemical fertilizer (CF). This study reveals the suitability of distillery sludge-based vermicompost to facilitate the growth of Raphanus sativus. An enhancement of the biomass, antioxidants (38.45–52.49%), total phenolics (22.56 mg GAE/g), and flavonoids (32.59–45.69 mg QE/g) was reported in the plants treated with the organic manures. However, reducing sugars (0.61 mg/50 g) was found to be in higher quantity in the plants treated with chemical fertilizer. Significant increase in the antioxidants including phenols and flavonoids along with enhanced DPPH and FRAP activity suggests the suitability of application of organic fertilizers to promote plant growth. Among the treatments offered, distillery sludge-based vermicompost was found to enhance the content of antioxidants (52.49 ± 0.002%), phenols (31.24 ± 0.002 mg GAE/g), flavonoids (45.69 ± 0.002 mg QE/g), mineral content (Ca, Mg, Na, K, P, Cu, Mn), and growth parameters too of Raphanus sativus, thus making the eco-friendly management of the distillery sludge possible. Further, there are no significant polymorphisms in the protein band of the DSV-grown radish.
