Abstract

Many metals in lower concentrations are considered beneficial for the growth of plants. But their elevation in soil severely influences the growth of plants by damaging their biochemical parameters. Co is a beneficial element but its higher amount in the growing medium can also be toxic for the growth of plants. Therefore, to study the toxicity of Co on maize, different levels (0, 50, 100, 150, 200, 250, & 300 µM) of this metal were applied in the soil. The morphological (Shoot and root length, shoot and root fresh weight, number of roots and leaves, leaf area, stem diameter), and photosynthetic attributes (Chl. a., Chl. b, Car.) were severely influenced by increasing the concentration of Co. The maximum disruption in all noted characteristics was calculated at 300µM while 50µM concentration was less toxic as compared to other levels.
