Abstract: Due to different activities by the human being like ore extraction and application of different processes causing the heavy metal mobility which leads to the addition of these elements in the environment. As we all know that nature of heavy metal is non- biodegradable hence accumulating in the environment and entering the food chain causing the contamination. These type of contamination having environmental risk as well as affecting the health of human. Heavy metal is mutagenic, endocrine, carcinogenic and teratogenic in nature which causes a neurological problem, especially in children. By considering all these points in mind remediation of these heavy metal is important to have a safe environment for survival. There are different methods for the remediation of heavy metal which are having the many limitations that are alteration of soil properties, high cost, disturbance in soil microflora and high demand labour. The present research work was carried out during the Zaid season in the Department of Agronomy as a pot culture experiment in the farm, School of Agriculture, Lovely Professional University, Phagwara. A pot experiment was set up with Zea mays, as test plant to evaluate the role of trichoderma, rhizobium and mycorrhiza mediated mitigation of chromium toxicity on morphological parameters. The result indicates that exposed plants to chromium toxicity (T1) showed the reduction in plant growth which includes a decrease in germination percentage by 33.32% as compared to control treatment (T0). The result indicates that average plant height was significantly decreased by 23.29%, 14.28% and 18.65% when plants are exposed to chromium stress (T1) as compared to the control (T0) at 30, 60 and 90 DAS respectively.
