Abstract: The present experiment was conducted at School of Agriculture under Department of Vegetables Science at Lovely Professional University, Jalandhar during winter season from September 2017- January 2018. The experiment was laid out in Randomized Block Design (RBD) with three replications. The three different concentrations of NAA viz. (50, 75 and 100 ppm) and three different concentrations of GA₃ (50, 75 and 100 ppm) were used over control. Among all the treatments, it was concluded that GA₃@ 50 ppm gave maximum plant height (70.83 cm), minimum number of days taken to 50% curd initiation (63.67 days), minimum number of days taken to 50% marketable curd size (80.33 days) and also increase yield and yield attributing characters such as curd diameter (62.93 cm), individual curd weight (0.89 kg), yield per plot (10.72 kg) and yield per hectare (238.22 q). From this experiment, it was concluded that 50 ppm of GA₃can be recommended in cauliflower for higher yield.
