A greenhouse trial was conducted to investigate the role of mycorrhizal and resistant fungi on heavy metal phytoextraction from different concentrations of tannery solid waste amended soil (10%,20%,50% and 100%) by Tagetes patula.The four treatments included were,the control (C) without any inoculum,mycorrhizal (M) inoculated with strongly mycorrhizal roots of Cynodon dactylon,fungal (F) inoculated with Trichoderma pseudokoningii and the combined inoculation with both mycorrhizal and fungal inocula (M+F).The dual inoculation increased plant biomass and phytoextraction ability of plant for metals like Cd,Cr,Cu,and Na.Plants given only fungus (F) and only mycorrhizal (M) treatment also showed significant growth rate as compared with control treatment.The statistical analysis of data indicated synergistic interaction between mycorrhizal and fungal inoculum promoting high biomass and enhanced metal phytoextraction.Thus using more than one group of rhizosphere fungi in association with a high biomass producing plant may be employed for rendering tannery solid waste free of metals.
