EFFECT OF NUTRIENT CONDITIONS ON THE GROWTH OF <em>CALAMUS</em> <em>MANAN</em> FROM FIVE PROVENANCES IN PENINSULAR MALAYSIA

Abstract

Calamus manan seedlings from five provenances (Bukit Lanjan, Gombak I and II, Kuala Lipis and Tapah) in Peninsular Malaysia were fertilised using seven different strengths of Hoagland solution (0/4H, 1/4H, 2/4H.3/4H, 4/4H, 5/4Hand6/ 4H). Twenty seedlings from each provenance were treated using the respective Hoagland strength replicated two times. Extension growth and leaf increment were observed over a three month period. Extension growth responses to Hoagland solution application varied with provenances and were more pronounced in the second and third month. Leaf increment was pronounced with higher Hoagland strength (5/4H and 6/4H).
