The current studies reveal the effect of a plant growth regulator (PGRs) on growth and yield performance of wheat crop. It was demonstrated that plant morphology, physiology, biochemistry and yield of wheat crop is highly effected/ stimulated by the use of low/ different concentration of growth regulators. Various filed experiments were conducted to investigate the effect of concentrations and formulations of three PGR salts (ortho-nitrophenolate, para-nitrophenolate and Sodium-5-Nitroguaiacolate). Various compositions of PGRs were applied as foliar application during different stages of plant growth. Control measurements were also carried out simultaneously using water only. A significant increase in plant height, stem growth, leaf development, chlorophyll contents and other biochemical contents of plant has been observed by the use of PGR. The results indicate that the PGR concentrations of 100 ppm and 150 ppm were found to give the best results. From the current study, it was suggested that dose concentration ranging from100ppm to 150ppm has momentous potential on plant growth and yield of wheat crop. Also it enhances the nutritional value of crop and reduces the economic cost of former.
