<i>Wedelia trilobata</i>-derived biochar mitigates chromium toxicity and improves physiological performance in hydroponically grown Chinese cabbage.

ABSTRACT:

Introduction

Ensuring future agricultural sustainability requires innovative solutions to alleviate abiotic stress caused by heavy metal(loid) contamination. Chromium (Cr) toxicity is a major abiotic stressor that threatens leafy vegetable productivity and food safety.

Methods

This study investigates the potential of Wedelia trilobata-derived biochar (WBC= 0, 0.1, 0.5, 1, and 3 g L-1) to mitigate Cr-induced abiotic stress (Cr = 50 mg/L, 7 days) in hydroponically grown Chinese cabbage (Brassica rapa). WBC was synthesized, characterized, and applied at varying concentrations in a flow-through hydroponic system.[Results] Results showed that WBC exhibited a strong chromium adsorption capacity. At an application rate of 3 g/L (T5), chromium accumulation in plant shoots and roots
