主 题：Toxic metals Withania somnifera Biochar Phytotoxicity
摘 要：Biochar is considered as a good metal sequester and ameliorates the metal toxicity and uptake in ***,its effec-tiveness over other organic amendments is not well *** aim of this study is to compare the biochar amendments alleviating the levels of Pb and Cd in Withania somnifera *** with other organic *** manure,vermicom-post,and biochar were applied in the field spiked with highly available Pb and *** bioavailability and accumulation,plant growth and plant physiology,antioxidant enzymes and metabolite content of *** along with soil properties were evaluated in all *** indicates that the application of organic manures significantly alleviated the metal levels(33-72%)in the plant in comparison with *** herbage yield was significantly higher(33-69%)under different organic manures as compared to the metal *** metabolite contents and antioxidant enzymes were higher in metal treatments in comparison with *** manures were not only able to restrain the Pb and Cd in soil but also enhanced the soil microbial *** indicate that biochar amendments were more promising than farmyard manure and vermicompost due to the presence of more stable carbon in biochar and more alleviation in metal *** addition,net profit in the cultivation of *** was higher for biochar amendments(50%higher)compared to *** study recommended that biochar could be a better option for commercial and safer production of ***.
