The effects of growth regulator applications (kinetin, IAA and Paclobutrazol) on field grown Salvia sclarea L. were studied during 2005 to 2006 at the Institute of Himalayan Bioresource Technology, Palampur, India. Growth was monitored by measuring plant height, canopy spread, leaf number, primary branches, and yield characteristics (inflorescence length and flower and oil yield). Quality was evaluated. Maximum height and leaf numbers were observed after application of kinetin 10 μL L
−1
and IAA 50 μL L
−1
, respectively. Maximum flower and oil yield were observed after application with 40 μL L
−1
paclobutrazol (PBZ) application. Application of 80 μL L
−1
paclobutrazol application increased the linalool-linalyl acetate content of the plant about 12% higher than the untreated control.
