Abstract: At the Agriculture Research Farm, Rama University, Mandhana, Kanpur, the present experiment, "Impact of Various Growth Regulators Applied through Foliar Application on the Development and Productivity of Cabbage (Brassica oleracea var. capitata L.)," was carried out from Rabi season 2023–24. Nine treatments (T₁ = Control, T₂ = GA3 25 ppm, T₃ = GA3 50 ppm, T₄ = GA3 75 ppm, T₅ = GA3 100 ppm, T₆ = NAA 30 ppm, T₇ = NAA 60 ppm, T₈ = NAA 90 ppm, and T₉ = NAA 120 ppm) were included in the Randomized Block Design (RBD) trial. The study's findings showed that treatment T₉ (NAA 120 ppm foliar spray at 30, 45, and 60 DAT) produced the highest plant heights at 30 DAT (14.97 cm), 45 DAT (24.81 cm), and 60 DAT (30.21 cm). Treatment T₈ = NAA (90 ppm) foliar spray at 30, 45, and 60 DAT produced the highest number of days to 50% head maturity, which was 47.76 days Although higher During the experimental year, the day-to-head maturity of the cabbage plant is (99.77) in T₁=Control treatment. Based on these findings, local farmers in the Kanpur areas might be advised to use treatment T₉ in order to get higher plant height and better-quality cabbage.
