ABSTRACT: The plant growth parameters of Patchouli (Pogostemon cablin Benth.) were significantly influenced by Bokashi treatment with maximum height, number of branches, plant spread, leaf size and leaf area index as 72.4 cm, 32.8 cm, 7818.63 cm², 64.88 cm² and 5.06 respectively. Application of Bokashi treatment provided the highest dry herbage yield of 4.67 t/ha against 3.96 t/ha in control by one time harvest. The essential oil content and oil yield per hector were also significantly influenced by the Bokashi treatment and it recorded 2.35 % (w/w) oil recovery when distilled after 30 days of curing. Essential oils from both the treatments of Patchouli were analyzed by GC-MS. Patchouli alcohol content both in Bokashi treatment and control are 45.330% and 44.669% respectively. Other major components are also higher in Bokashi treatment than control.

KEYWORDS: Pogostemon cablin; Bokashi; Herbage yield; Patchouli alcohol.
