The present investigation was conducted at the experimental field of Dau Kalyan Singh College of Agriculture and Research Station, Bhatapara, under Department of Floriculture and Landscape Architecture, IGKV, Raipur (C.G.) during 2018 - 19 in Rabi season in factorial randomized block design in three replications with 14 treatments combinations. The experiment comprised of two factors, i.e., planting geometry (30 x 45 and 30 x 30) and plant growth regulators (GA₃ @ 150 and 200 ppm, NAA @ 50 and 100 ppm, MH @ 500 and 750 ppm, with water spray). The study revealed that the planting at 30 x 30 cm increased the plant height and planting space at 30 x 45 cm enhanced number of leaves per plant, number of branches per plant, spread of plant, number of flowers per plant, flower size, single flower weight. Among different plant growth regulators, maximum plant height, number of leaves per plant, number of branches per plant, spread of plant, number of flowers per plant, flower size and single flower weight observed from the plants sprayed with treatment containing GA₃ @ 200 ppm. The interaction of S₂P₂ (30 x 30 cm, GA₃ @ 200 ppm) recorded higher plant height and treatment combination of S₁P₂ (30 x 45 cm, GA₃ @ 200 ppm) recorded number of leaves per plant, number of branches per plant and plant spread.
