Brinjal (Solanum melongena L.) member of angiospermic family solanaceae is also known as eggplant. The present investigation was carried on Rabi-2021 brinjal cv. Purple round at the Horticultural Research Farm, Sardar Patel University, Balaghat (M.P.). The experiment was laid out in a Randomized Block Design (RBD) with ten treatments in three replication. Three plant growth regulators namely, naphthalene acetic acid (NAA), gibberellic acid (GA3), and 2,4-dichlorophenoxyacetic acid (2, 4-D). The concentration of NAA (20, 40 and 60 ppm), GA3 (25, 50 and 75 ppm), and 2,4-D (2, 4 and 6 ppm) were selected for the experiment. The data revealed that maximum fruit yield per plant (3.09 kg) was recorded in the treatment T₆ i.e. GA3 75 ppm, followed by treatment T₂ i.e. NAA 40 ppm (2.80 Kg) with mean of 2.24 kg. However minimum (1.15 kg) was recorded in treatment T₁₀ i. e. control. Among the all three plant growth regulators i.e. NAA and 2,4-D relates to auxins group and GA₃ to the group of gibberellins, GA₃ 75 ppm application is very effective for enhancement of vegetative and yield traits.
