Abstract: Tree growth is a function of the genetic potential of the species and environmental condition. Before introducing a species to a given ago-ecology there is always a need for well conducted field trial for matching the species/provenance to a particular site. To this end, a study was conducted at Chattarpur farm of Zonal Research Station Chianki, Birsa Agricultural University Ranchi, Jharkhand. during2015-16 and 2016-17 to evaluate adaptation and growth performance of different tree and shrub species were compared in randomized block design with three replications. Results revealed that there were highly significant (P<=0.5) variations among species in height growth, collar diameter development and survival after two years of age. This could be due to environmental factors and/or genetic potential of the species, which generally govern the growth of a given species Among the species tested Khair (Acacia catechu L.) showed superior performance in terms of height increment (154.30 cm)and diameter increment (20.40 mm) growth whereas, after two years of experimentation. Khair (Acacia katechu) and Chakundi (Cassia samea) showed highest survival rate (98%).Hence, it can be inferred that the condition of Palamau region matched well with the environmental requirement of Khair and Chakundi.
