Introduction: The appropriate management of fish waste is crucial in the fishing and processing industry, necessitating effective waste management strategies. Composting, which is rich in nutrients, is a well-regarded method. This study aimed to assess the impact of fish waste compost, an eco-friendly fertilizer, on the growth and performance of red radish plants, as well as its influence on heavy metal interactions and catalase enzyme activity. Methods: Under greenhouse and pot conditions, two studies with three treatments and three replications were carried out. In the first experiment, the effects of 20% and 50% compost on the morphological traits of radish plants were examined. In the second experiment, 50% compost was chosen based on the plant's morphological traits, and the characteristics of heavy metal removal and catalase enzyme activity were assessed. Results and discussion: Results demonstrated that the use of 50% compost led to notable improvements in the fresh and dry weights of leaves and tubers, alongside increased proline content (5g, 0.05g, 6.6g, 1.91 µmol g-1 DW) in the plants. Furthermore, the 50% compost reduced cadmium activity (0.21 mg/kg) and enhanced catalase enzyme activity (34 µmol hydrogen peroxide/g-hour). Employing fish waste compost has the potential to enhance soil quality and decrease the impact of heavy metals in agricultural settings, ultimately facilitating an optimal environment for plant growth.
