Bergenia ciliata L. is a rhizomatic herb with fleshy leaves, growing up to 30 cm tall has medicinal values, and is used for the treatment of different diseases under traditional and ayurvedic systems since ages. Although Bergenia ciliata is found growing at an altitude of 1200-3000 m in the natural forests of Kashmir Valley. An attempt was made to propagated it in open nursery beds using different diameter classes and spacings. Rhizomes planted in open nursery beds rooted and survived 100 percent during the first growing season, but there was a difference in their growth characteristics. Growth parameters showed an increasing trend with the increase in diameter class and spacing. Rhizomes of higher diameter class 2.25-3.0 cm showed better performance under field conditions at a spacing of 60 cm × 75 cm in terms of survival percentage, rooting percentage, number of leaves per plant, leaf area (cm2), leaf fresh weight (g/plant), root length (cm), rhizome diameter (mm), above-ground biomass (g/plant), below-ground biomass (g/plant) and total biomass (g/plant). Also maximum essential oil content of (15.10 l/ ha, was extracted from leaves and Rhizomes of the harvested material planted in open from the diameter class of (2.25 to 3 cm) and planted at a spacing of ( 60 x 75 cm) D4S4 respectively. It is recommended that the diameter class (2.25-3.0 cm) and spacing of (60 cm × 75) cm should be followed to cultivate Bergenia to get a better yield of the crop and essential oil.
