Abstract
The present study was under taken to identify best spacements of Casuarina equisetifolia L. for its growth and development as well as nutrient status of soil in South Gujarat condition. The experiment was laid out in randomized block design (RBD) with six replications. The composite soil samples were taken at upper (0-45 cm) depth of the soil. Among all the spacements of Casuarina equisetifolia, 2.0 x 2.0 m spacing recorded maximum impact on the status of major (266.00, 59.62 and 441.59 kg ha-1, respectively for N2, P2O5 and K2O) and micro (19.64, 45.58, 1.21 and 1.35 mg kg-1, respectively for Fe, Mn, Zn and Cu) nutrients as well as organic carbon content (1.13 %) in soil. The needle fall (0.65 kg/m2), thickness of needle fall (7.9 cm) and tree height (20.44 m) were recorded maximum in T1 (2.0 x 2.0 m). While, girth at breast height (78.75 cm) and crown width (3.90 m) were recorded significantly maximum in T4 (8.0 x 2.0 m) spacing.
