A field experiment was conducted at the Herbal Garden of Department of Forestry, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). During the year 2021-22 with a view to study the “Effect of PGR on Yield of Patchouli (Pogostemon cablin) Under Karanj (Pongamia pinnata) Based Agro-forestry System”. The Patchouli intercrops under Karanj tree crop were used to grown and treatment was replicated three times in randomized block design (RBD). The soil of experimental field was clay to loam soil. The investigation, There were three growth regulators and chemicals(NAA, Miraculan and GA) were used, which were applied at different concentrations in Patchouli in eight treatments viz., T1: - Control (Basal Dose) (150:50:50 kg NPK ha-1), T2: - Basal Dose + NAA @ 20ppm, T3:- Basal Dose + NAA @ 25ppm, T4:- Basal Dose + NAA @ 30ppm, T5:- Basal Dose + miraculan @ 100ppm, T6:- Basal Dose + miraculan @ 150ppm, T7: - Basal Dose + GA @ 20 ppm and T8:- Basal Dose + GA @ 30ppm.The yield parameters i.e., fresh herbage yields (q ha-1), Dry herbage yield (q ha-1) and oil yield (kg ha-1) were significantly superior in the treatment T7 (GA @ 20 ppm). On the basis of above findings, treatment T7 (GA @ 20 ppm) stand could be better performance first in position and T8 (GA @ 30ppm) stand in second order of preference. However, treatment T3 (NAA @ 25ppm) comes in next in order. Therefore, it may be concluded that treatment T7 (GA @ 20 ppm) may be prefer for higher yield in patchouli.
