Seedlings of Acacia auriculiformis, A. catechu, A. mangium, Albizia lebbeck, A. procera, A. samara, Cassia fistula, C. Siamea, Gliricidia sepium, Dalbergia sissoo and Leucaena leucocephala were raised in polybags containing the soil of barren hilly areas of Chittagong University campus situated at the south-eastern part of Bangladesh. The study was conducted to evaluate comparative germination, growth, leaf pigments and nodulation status with a view to select suitable species for afforestation and reforestation programmes in the degraded hilly areas of the country. Initial growth response determined f shoot and root length, collar diameter, dry weight of shoot and root of the seedlings were found highest in G. sepium followed by A. lebbeck and A. procera. However, the nodule number was significantly (p less than 0.05) highest (143) in A. saman followed by A. procera and G. sepium, but the dry weight of nodules were maximum (1.54 g & 0.52 g respectively) in A. procera. The of the nodules varied from 2.7 mM x 2.6 mM in D. sissoo to 6.3 mM x 3.5 mM in A. mangium. Most of the species possessed nodule of both in single and aggregated forms. Maximum leaf pigment (106.51 mg/L) was recorded in G. sepium followed L leucocephala and A. catechu. In comparison, G. sepium, A. lebbeck and A. procera possessed better growth performance while C fistula was the poorest growth performance.
