This study evaluates the use of biochar as a sustainable substitute to peat in soilless cultivation rocket salad (Eruca vesicaria (L.) Cav.). Biochar was added peat-based substrate at concentrations 0% (control), 5%, 10%, 20%, 40%, and 70% v/v assess its effects on seed germination, plant growth, mineral content, nitrate accumulation. The results show that up 40% maintained germination rates above 80%, similar control, while higher (70% v/v) drastically reduced 29% entirely compromised development growth. A moderate concentration (20%) had positive effect fresh weight leaf area, maintaining comparable levels nutrient uptake, chlorophyll, flavonols. In addition, biochar-enriched substrates (≥20% accumulation leaves by 26–30%, addressing critical quality safety concern. high content (≥40% altered substrate’s physicochemical properties, including pH, porosity, electrical conductivity, negatively affecting growth (a 38% reduction 42% area) increasing heavy metal concentrations, such zinc (~30%). These findings suggest incorporating 20% offers alternative peat, supporting performance improving quality, without compromising yield or safety.
