Abstract:
The present experiment was conducted during Rabi 2020-2021 at Precision Farming Development Centre (PFDC), Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The research was conducted in RBD with 9 treatment combinations in three replications. In this experiment the four different concentrations of NAA viz. (80, 100, 120 and 140 ppm) and four different concentrations of GA₃ (50, 100, 150 and 200 ppm) were used over control. Among all the treatments, it was concluded that for growth attributing characters T3- GA₃150 ppm gave maximum plant height (cm) at 30, 45 and 60 DAT (28.77, 40.67, 45.00), No. of leaves/ plant at 30, 45 and 60 DAT (10, 14, 21), canopy spread (cm²) at 30, 45 and 60 DAT (39.33, 55.50, 73.17), length of leaves (cm) at 30, 45 and 60 DAT (18.67, 30.00, 37.00), width of leaves (cm) at 30, 45 and 60 DAT(10.00, 16.33,19.20), minimum no. of days from transplant to the start of the curd (44.00), minimum no. of days from transplant to 50% curd formation (57.00), minimum no. of days from transplant to harvesting of crop (67.00), the minimum was recorded under T9-control. From this experiment, it was concluded that 150 ppm of GA₃ can be recommended in cauliflower for higher growth attributing characters.
