Abstract

A trial was conducted over 4 yr with 8 species (7 Calamus spp. from the Andamans, Karnataka, Kerala and Malaysiaand Daemonorops kurzianus from the Andamans) at 2 localities (300 and 1000 m altitude) in Kerala. C. rotang performed best in terms of growth in height and survival percentage. C. pseudorivalis and C. karnatakensis were suitable for use in large-scale plantations at medium altitude and D. kurzianus at higher altitudes. The other species included in the trial were C. andamanicus, C. caesius, C. gamblei and C. pseudotenuis
