Relationsmp between DBH and Wood Volume in Casuarina equisetifolia

A field experiment was conducted at Sugarcane Research Station (Tamil Nadu Agriculture University) Cuddalore during 1993-96 to find out the effect of bioinoculants, nitrogen and phosphorus fertilizers on the growth and wood volume of Casuarina equisetifolia. The data collected from the study were used for the development of prediction equations for the non destructive estimation of various components of dry matter of Casuarina equiselifolia viz. bole weight, branch weight, foliage weight and ischolar_main weight from the easily measurable data like tree height and DBH (Diameter at Breast Height). The results of the path coefficient analysis revealed that the DBH showed maximum predominant direct effect since it is the best predictor to decide the wood volume of Cusuarina equisetifolia.
