dc.description.abstract In this paper we evaluated the phytotoxicity of different composts obtained by two different composting methods using seed germination bioassay. Seeds of Zea mays were sown in 1:5 extract of composts and these were compared with the control (100% distilled water) for each type of material. Composting of herbal pharmaceutical solid waste (HPSW) was carried out using both conventional bin and pit method. HPSW was mixed separately with poultry manure, cow-manure and goat manure in three different ratios. Uncomposted and composted HPSW were tested to study the Phytotoxicity on Zea mays seed germination, after composting increase in percent germination as well as germination index (GI) values were observed in all combinations regardless, composted by pit or bin method. The results clearly showed that composting reduced Phytotoxicity. The results showed that use of completely composted organic waste reduces the phytotoxicity and is better than the use of uncomposted waste. It was found that pit method was more suitable than bin method. Herbal waste with goat manure in 1:1 ratio was found to be the most effective combination as compared to other combinations here. Germination was 100% and the germination index was 1.4 whereas uncomposted HPSW showed the lowest percent germination i.e., 77% and germination index 52.31 respectively en_US
