Abstract: Studies were the effect of spacing regimes on growth and yield of Enterolobium cyclocarpum for its suitability in various fields of utility as a Multipurpose Tree Species adoptability in northern zone of Tamil Nadu.In evaluation of spatial trial plantation for its biometric measurements with four different spacing, the trees exhibited better increments of height and diameter over periodic measurements taken at a month interval. Hence, height and diameter could be considered as selection criteria in evaluating trees.The results are revealed that, the planted at 1.5 m x 1.5 m spacing exhibits maximum height growth (4.92 m) at 24 months after planting followed by the planted at 2 m x 2 m spacing (4.80m). The maximum diameter at breast height (DBH) was recorded for the planted at 1.5m x 1.5m spacing (0.098m) followed by 3m x 3m spacing (0.078m). In the spacing of 1.5 m x 1.5 m, spacing exhibits maximum height growth and volume.Enterolobium cyclocarpum is suitable for northern zone of Tamil Nadu. Hence, tree adopted in northern zone of Tamilnadu.
