The present study was conducted to determine the effect of cadmium(Cd) on enzyme activity of black gram (vigna mungo.(L)hepper).The black gram seeds were treated under control, 2.5, 5, 7.5, 10, and 12.5 mg of Cd. Every treatment was replicated thrice in a randomized block design. Observations were complete on enzyme activity of catalase,peraxidase of black gram .all result when compared with control show that cadmium metal adversely affects the growth of black gram by reducing enzyme activity.The present research work was to find out the effect of different concentrations of cadmium with AMF on, enzymatic activity, of black gram grown under pot culture experiment.
