Abstract: The present experiment was conducted at School of Agriculture, Department of Vegetable Science at Lovely Professional University, Jalandhar during the winter season from October 2017 - December 2017 to study the effect of different plant growth regulators (GA₃ and NAA) on growth and yield parameters of radish (Raphanus sativus L.) var. Pusa Reshmi. The experiment was laid out in randomized block design (RBD) with three replications. The treatments used were i.e. three different concentrations of GA₃ (5, 10, 15 ppm) and three different dose of NAA (10, 20, 30 ppm) and control to improve various growth and yield contributing parameters of Radish. Among all the treatments, it was concluded that higher dose of GA₃ at 15 ppm results in increasing maximum leaf length, plant height and it also increases the yield attributing characters such as root length, fresh weight of roots, root yield kg/plot and as well as highest over control. From this experiment, it was concluded that the application of GA₃ 15 ppm can be recommended in radish for higher root yield.
