The present investigation entitled “Effect of plant growth regulators on growth and yield of cabbage (Brassica oleracea var. capitata)” was carried out at Horticulture farm, Department of Horticulture, School of Agricultural Sciences, JRNRV, Udaipur during Rabi season 2023-24. The experiment was conducted in Randomized Block Design with three replication comprising eight treatment combinations. Result showed that among growth regulators application of T9 treatment (GA3 + NAA @ 50-50 ppm) recorded maximum values of different growth, yield and economics characters of cabbage such as maximum plant height (18.32 cm, 30.10 cm and 34.75), number of leaves i.e. 12.15, 14.25 and 17.82, stalk length i.e. 3.72 cm, 5.22 cm and 5.81 cm at 30, 45 and 60 days, diameter of head i.e. 49.15 cm, head weight 1.65 kg, head yield i.e. 31.28 ton/ha.
