dc.description.abstractProductivity assessment of Acacia auriculiformis plantations of three age gradations (viz., 8, 10 and 12 years old) in different forest ranges (Sirsi, Banavasi, Hulekal, Janmane, Siddapur, Kyadagi) of Sirsi forest division was taken up and each range was considered as different ecological situation. Observations on growth parameters like total tree height, clear bole height and dbh were recorded in 10 m  10 m sample plot. As substantial area is being occupied by different Acacia species in Uttara Kannada district studies were necessary to know the variation among plantation of different age gradations within a broad zone. The results of the study revealed that total volume was highest in Kyadagi ecological situation (118.81 m3/ha) followed by Siddapur (118.05 m3/ha) at 8 years, while it was Janamne (320.02 m3/ha) followed by Hulekal (319.07 m3/ha) at 10 years and Siddapur (361.47 m3/ha) followed by Kyadagi (359.58 m3/ha) at 12 years. The carbon stock was highest in Kyadagi (32.68 t/ha), Janmane (88.00 t/ha) and Siddapur (99.40 t/ha) situations at 8, 10 and 12 year age gradations respectively. The growth and productivity parameters were positively correlated with climatic and edaphic factors in all the three age gradations. The carbon stock with respect to ecological situations was significant among all the age groups and interaction between ecological situations and age with respect to all parameters was also significant. The study indicated that locality factors such as rainfall, temperature, microclimate and edaphic factors played key role in growth and productivity of Acacia auruculiformis plantation in Sirsi forest division.en_US
