Cadmium (Cd) is considered most toxic heavy metal because it is highly soluble in the water. Naphthalene acetic acid (NAA) is growth regulator from auxins family and having positive role under cadmium stress. A pot experiment was held to minimize the effect of heavy metal cadmium on wheat growth by using naphthalene acetic acid as foliar spray. The trial was conducted in the glass house, Faculty of Agriculture, University of Agriculture Faisalabad. The experimental design was completely randomized (CRD) and the replications were four. This experiment was consisted of two factors. Cadmium concentrations were 0, 50 and 75 ppm. Growth regulator naphthalene acetic acid was used at 0, 25, 50 and 75 ppm as foliar spray. Response of wheat to applied Cd and NAA was observed by studying various growth, biomass and yield parameters. Data was collected and analyzed using suitable statistical techniques. Growth, biomass and yield were positively affected by naphthalene acetic acid. Foliar applied naphthalene acetic acid in overcoming the negative effect of cadmium stress on growth, biomass and yield of wheat. The level of 50 ppm applied naphthalene acetic acid proved best in this regard.
