The present investigation carry out the effect of different concentration of zinc(zn) on the morphological parameter of different varieties of ground nut plant. The ground nut plants were raised in plastic cup containing the soil (1kg) with different concentrations of zinc (zn) (control, 2.5,5,7.5,10 mg kg-1 soil). Three replicates were maintained for each level. The plant samples were collected at 7th DAS for the measurement of different growth parameters. The selection of morphological parameters such as root length, shoot length, number of leaves, fresh and dry weights vigour index, tolerance index and phytotoxity of ground nut were determined for all the sampling days. All the parameters increased in control treatments, 10 mg kg-1 zinc (zn) treatment decreased of ground nut.
