Abstract

Irawan A, Kafiar Y. 2015. Use of sawdust and rice husk as a growth media of cempaka wasian (Elmerrilia ovalis). Pros Sem Nas Masy Biodiv Indon 1: 805-808. The use of topsoil is still the main choice as weaning media in the forestry plant nursery. On the other hand, the use of top soil in large amounts could adversely affect the environmental balance. This study aimed to determine the effect of the use of organic materials cocopeat and rice husk as a composite medium of top soil as a growing medium for the growth of cempaka wasian seedlings. The experimental design was a Completely Randomized Design with three treatments and three replications. The treatments tested were the differences in the use of planting medium consisting of (i) top soil; (ii) top soil+cocopeat; and (iii) top soil+rice husk. The results showed that the rice husk provided a better response to the growth of cempaka wasian seedlings than cocopeat.
