The current study focused on effect of different potting media and biostimulants on growth and survival percentage of bougainvillea (Bougainvillea spp.) cuttings. The research was conducted at the Hi-tech unit of the College of Horticulture, Dapoli, under the auspices of Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Dist. Ratnagiri, Maharashtra, utilizing a Factorial Randomized Block Design (FRBD) within a partially protected environment, specifically a green shade net house, with three replications and fifteen treatment combinations. The investigation involved five different potting medias viz. (M₀) Soil + FYM (control) (3:1), (M₁) Soil + Sand + Vermicompost (1:1:1), (M₂) Soil + Cocopeat + Vermicompost (1:1:1), (M₃) Soil + Cocopeat + Rice husk (1:1:1) and (M₄) Soil + Vermicompost + Rice husk (1:1:1) alongside three biostimulants (B₀) (IBA (0.5%) Control, (B₁) Humic acid (0.3%) and (B₂) Chitosan (0.01%). Findings revealed that combination M₂B₀ (Soil + Cocopeat + Vermicompost (1:1:1) combined with IBA @ 0.5%) significantly improved plant height (42.35 cm), stem girth (13.29 mm), Number of shoots (4.47), number of leaves (45.67) and leaf area (32.86 cm²). The highest survival percentage (74.77) was also recorded in combination M₂B₀.
