This study investigated the potential toxycity in vitro of biochar as well as water extract from biochar on seed germination of Oryza sativa, Brassica juncea, Vigna radiata, Solanum lycopersicum and Zea mays by Petri assay. Rice husk biochar does not affect on Oryza sativa germination (GI ) as well as has insignificant inhibition to Vigna radiata and Zea mays germination but adversely affecting on Brassica juncea and Solanum lycopersicum germination. |
