The experiment was laid out to study the influence of morphological parameters on survival and establishment of seedling at the out planting site. Seedlings were categorized into four diameter (<2.5, 2.5-3.5,3.5-4.5 and >4.5 mm) and top height (<10, 10-20,20-30 and >30 cm) classes and transplanted during the month of March. Seedlings having a diameter of >4.5 mm exhibited the highest survival (77.27%), diameter increment (1.55 mm) and total dry biomass (15.64 g). Whereas, the maximum height increment (14.18 cm) and number of leaves (6.25) were displayed by the seedlings under 3.5-4.5 mm diameter class. Seedlings of having <2.5 mm diameter resulted in the poorest survival, growth and biomass. Seedling height of >30 cm recorded the highest survival (71.0%) and total dry biomass (11.73 g). Whereas, the seedling having initial top height of 20-30 cm registered the maximum height increment (15.43 cm) and number of leaves (6.54) after seven months of out planting.
