Abstract: The study entitled “Effect of inorganic, organic and biofertilizers on growth characteristics of Albizzia lebbeck (L.) Benth at seedling stage” was conducted in research plots of faculty of forestry, BAU, Ranchi during the session 2018-2019. The nursery layout was made according to the requirements of the study. The study was conducted for time period of 6 months. The various treatment compositions were made by using inorganic, organic and biofertilizers with various levels. The seed characteristics were studied before sowing into the polybag. The germination, growth and quality parameters of Albizzia lebbeck under the influence of various treatments were studied. The growth parameters showed variation among the treatment combinations. Albizzia lebbeck seedlings under influence of applied treatment combinations showed that maximum was in PSB and Urea (40.73 cm), maximum was in PSB and Urea (29.10 cm), maximum was in Brady rhizobium japonicum and Karanj cake (5.07 mm). The quality parameters were found to be significantly different between treatments Albizzia lebbeck seedlings under influence of applied treatment combinations showed that maximum was in treatment containing sole Urea (1.29),vigour index (V.I) of Albizzia lebbeck seedlings under influence of applied treatment combinations showed that maximum was in treatment in PSB and Urea combination (6486.65),sturdiness quotient (S.Q) of Albizzia lebbeck seedlings under influence of applied treatment combinations showed that maximum was in PSB and Urea combination (8.95) and Dickson quality index (Q.I) of Albizzia lebbeck seedlings under influence of applied treatment combinations showed that maximum was in Brady rhizobium japonicum(1.92). The available nitrogen was found maximum in treatment combinations of Brady rhizobium japonicum and Karanj cake (T₇) i.e. 371.2 kgha^-1. While available phosphorous was found maximum in treatment combinations of PSB and Urea (T₈) i.e. 37.83 Kgha^-1.
