TL;DR
This study explores using fish waste as a bio-fertilizer to help stevia plants cope with salt stress, showing promising results in improving plant growth and reducing stress effects.
Contribution
The novelty lies in proposing fish waste as a sustainable bio-fertilizer to mitigate salinity stress in plants.
Findings
Salinity stress negatively impacted stevia plant growth and photosynthetic parameters.
Fish waste bio-fertilizer reduced stress markers and improved growth under high salinity.
Fish waste application did not exacerbate salinity issues within tested doses and duration.
Abstract
Currently, different strategies, including the application of bio-fertilizers, are used to ameliorate the adverse effects posed by salinity stress as the major global problem in plants. Fish waste is suggested as a novel bio-fertilizer to mitigate the effects of biotic and abiotic stresses. In this investigation, an experiment was conducted to investigate the effects by applying different concentrations (0, 5, 10, and 15% (v/v)) of fish waste bio-fertilizer on stevia plants grown under salt stress conditions (0, 20, 40, and 60 mM of NaCl). Results showed that salinity negatively affected growth parameters, the photosynthetic pigments, the relative water content, and the chlorophyll fluorescence parameters while increased the activity of antioxidant enzymes, total phenol, hydrogen peroxide (H2O2), malondialdehyde (MDA), proline, and total carbohydrates compared with control samples.
