ELIMINATION OF PHYTOTOXICITY DURING CO- COMPOSTING OF ANIMAL CASING WASTE AND SAWDUST

In this study, the plant seed germination technique was used to assess the phytotoxicity of animal casing waste and sawdust during composting process on the relative seed germination, relative root elongation, and germination index of Cress (Lepidium sativum L.). The composting process was carried out using barrel system. The compost was prepared by mixing animal casing waste (ACW) and sawdust (S). At the end of the composting period, the germination percentage was 81 % which indicates the elimination of phytotoxicity and a compost maturity.
