Abstract:Mensurational attributes of Schizostachyum dullooa, at four culm ages of 7 girth classes (3-5 cm to 15-17 cm) were studied from Cachar district of Assam, North East India. Internode length, internode number per culms, internode circumference, total culm height, total culm green weight and total culm solid volume of the selected age classes culms were studied. A total of 144 numbers of culms were harvested for this study. Three replicates were taken from each girth class sizes of all age classes. Maximum culm height was observed in 3-yr-old culms (8.3 m) followed by 4, 2 and 1-yr-old culms. This may be due to competition for nutrients as the number of individual's increases in the clump. Maximum average internode length was observed 0.98 m. Total culm green weight ranges from 278 g to 4640 g. with average maximum in 3-yr-old culms. Total culm solid volume was observed maximum in 2-yr-old culms followed by 3, 4 and 1-yr. Best fitted regression models for all parameters were developed. Developed different regression models will enable sustainable utilization and management of the species.
