Casuarinas are among the most important tree species for the production of high yielding wood biomass for fibre, rayon and energy needs. Among the 96 species of trees and shrubs in the family Casuarinaceae, Casuarina equisetifolia has gained much attention due to its multiple end-uses. India is the largest Casuarina growing country in the world, with an estimated 800,000 ha of plantations. About 500,000 ha are planted with Casuarina in the coastal states of Andhra Pradesh, Orissa, Tamil Nadu and the Union Territory of Puducherry. In order to assess early growth of casuarina hybrid clones for agroforestry, an experiment was conducted at MAHRS, Iruvakki, Shivamogga, Karnataka. Eight casuarina hybrid clones were planted in row-column design with 3 replication and 3 x 2 m spacing. The observations on height (ht) and collar diameter (CD) were recorded up to 9 months. Stem form (axis persistence and stem straightness), branching habit (thickness and length) were assessed by scoring. There was significant difference in quantitative and qualitative parameters observed for eight casuarinas hybrid clones. Considerable height was recorded in CH2, CH4 and CH5 (2.68 m, 2.72 m, and 2.67 m respectively) at nine months after planting. These clones have also performed better in qualitative parameters compared to clones CJ9 & HPF as these were not suitable for high rainfall areas.
