The experiment was conducted to find out the vegetative propagation of patchouli (Pogostemon cablin (Blanco) Benth.) inside the mist chamber at Allahabad region of Uttar Pradesh, India . Three different sizes of stem cuttings (8, 10, and 12cms) of patchouli were dipped in different concentration of IBA (500, 1000, 1500 ppm) with control condition to check the best fit concentration in respect to its rooting behavior. It was observed that the rooting response of Patchouli varied with size of cuttings, season and concentration of IBA. The maximum plant height (14.93 cm), number of leaves (16.49) and collar diameter (4.92 cm), were recorded in the 12 cm cuttings with 500 ppm. Similarly patchouli cuttings treated with IBA-500 ppm registered equally high root length (6.46cm) and root number (82.36) with good root quality.
