Abstract
This study investigates the influence of treated biosolid(aerobically) and vermicompost on the yield, morphological characteristics, and nutritional composition of two leafy vegetables—Coriandrum sativum (coriander) and Amaranthus viridis (green amaranthus)—under controlled plant bed experiments. Three sets of trials were conducted, testing four soil treatments: Red Soil (control), Red Soil + Biosolid, Red Soil + Vermicompost, and a combination of all three (Red Soil + Biosolid + Vermicompost). Parameters such as germination rate, shoot/root length, biomass, leaf area, crude protein, total ash, and heavy metal accumulation were analyzed. Results consistently indicated improved growth and nutritional quality in soils amended with biosolids and vermicompost, particularly biosolid-alone treatments. However, the combined treatment often resulted in reduced performance, especially in root and shoot length, indicating possible antagonistic effects. While biosolids enhanced plant productivity and mineral uptake, a slight elevation in heavy metal concentrations—particularly lead and arsenic—was observed, necessitating caution. Overall, treated biosolids can serve as effective soil amendments, but their application should be carefully managed to balance yield improvements with food safety considerations.
