A field investigation entitled “Influence of Different Concentrations of Growth Regulators on the Stem Cuttings of Dragon Fruit” was carried out at the Horticulture Research Farm, College of Horticulture and Research Station, Saja, Bemetara (C.G.) during 2024-25. The experiment was arranged in a Completely Randomized Design (CRD) with three replications. The trial consisted of twelve plant growth regulators management practices viz., T₀: Control (Distilled water), T₁: IBA 2000 ppm, T₂: IBA 4000 ppm, T₃: IBA 6000 ppm, T₄: NAA 100 ppm, T₅: NAA 200 ppm, T₆: IBA 2000 ppm + NAA 100 ppm, T₇: IBA 2000 ppm + NAA 200 ppm, T₈: IBA 4000 ppm + NAA 100 ppm, T₉: IBA 4000 ppm + NAA 200 ppm, T₁₀: IBA 6000 ppm + NAA 100 ppm and T₁₁: IBA 6000 ppm + NAA 200 ppm. Data were recorded on rooting traits (number of roots per cutting, root length, and root diameter) as well as shoot growth parameters (days to first sprouting and shoot length). The findings indicated that T₃ (IBA 6000 ppm) excelled in most parameters, producing the maximum number of roots (23.98), root length (23.25 cm), root diameter (0.54 cm) and shoot length (19.15 cm). This treatment also recorded the earliest sprouting, showing significant superiority over other treatments. It was followed by T₂ (IBA 4000 ppm), which was statistically on par with T₃. Moderate responses were observed with T₆ (IBA 2000 ppm + NAA 100 ppm), T₇ (IBA 2000 ppm + NAA 200 ppm), T₈ (IBA 4000 ppm + NAA 100 ppm) and T₉ (IBA 4000 ppm + NAA 200 ppm). Treatments with NAA alone (T₄ and T₅) showed comparatively lower performance, while the minimum values were recorded in the control (T₀), which produced 9.63 number of roots, 12.41 cm root length, 0.14 cm root diameter and 7.85 cm shoot length.
