Abstract:
Present experiment entitled “Effect of foliar spray of GA₃ and NAA on growth, yield, and quality of cabbage (Brassica oleracea var. capitata L.)” was conducted during the Rabi season of 2022 - 23 at Agriculture Research Farm, Rama University, Mandhana, Kanpur. The experiment was laid out in Randomized Block Design (RBD) with three replications and nine treatments viz. T₁ =Control, T₂ =GA₃ 30 mg foliar spray at 30 DAT, T₃ =GA₃ 60 mg foliar spray at 30 DAT, T₄ =GA₃ 90 mg foliar spray at 30 DAT, T₅ =GA₃ 120 mg foliar spray at 30 DAT, T₆ =NAA 50 ppm foliar spray at 30 and 45 DAT, T₇ =NAA 75 ppm foliar spray at 30 and 45 DAT, T₈ =NAA 100 ppm foliar spray at 30 and 45 DAT, T₉ =NAA 125 ppm foliar spray at 30 and 45 DAT. The result of the study revealed that the maximum plant height (29.5cm), leaf length (28.50cm), leaf width (27.78cm), Number of open leaves (12.5) stalk length (11.40cm), minimum days of harvesting from transplanting (90.40), head diameter (50.8 cm), head weight (1.30kg) yield/ ha (35.67q/ha), TSS content (4.43 ºBrix), and acidity (2.50%) was reported in treatment T₉ (NAA 125 ppm foliar spray at 30 and 45 DAT) followed by treatment T₈ = NAA (100 ppm) foliar spray at 30 and 45 DAT. Basis on these results treatment T₉ can be suggested to the local farmer of Kanpur regions to obtain higher yield and better quality of cabbage.
