Comparision of Growth Performance in Timber Tree Species Cultivated under Drip Irrigation on Farm Lands

A field experiment was conducted at Forest College and Research Institute, Mettupalayam, Tamil Nadu, India to study the growth performance of Neolamarckia cadamba, Acrocarpus fraxinifolius and Dalbergia sissoo under drip irrigation. The biometric attributes viz., height, basal diameter and diameter at breast height (DBH) were studied during 3 month after planting (MAP), 6 MAP, 9 MAP and 12 MAP. Among the three fast growing tree species, Neolamarckia cadamba exhibited a maximum height of 4.40 m, basal diameter of 5.31 cm and DBH of 5.03 cm followed by Acrocarpus fraxinifolius (Height of 3.99 m, basal diameter of 4.52 cm and DBH of 4.26 cm) and minimum in Dalbergia sissoo (Height of 3.37 m, basal diameter of 3.45 cm and DBH of 3.96 cm). The drip technology in tree species responded well to the drip irrigation system.
