This study was initiated after recognizing the importance of growth and yield studies of plantation-grown pioneer fast growing species for future forest management decisions, coupled with a general paucity of knowledge on the growth and potential yield of the species planted under plantation condition.  The species of Macaranga  tanarius is regarded among the most promising Macaranga genus because of the seed availability throughout the year and potentially seed germinated after probing trial established compared with other species

The studies will provide an opportunity to generate baseline information for future planting of M. tanarius under plantation condition.  Information on growth and potential yield of the species can be used in the planning for future establishment and management planning for future M. tanarius plantations.

Growth performance from each provenance were collected and planted in four established plantation plots in SPF Jeli, SPF Maya Ayer, SPF Selandar, Melaka and Field 52 Bukit Hari, FRIM HQ. The trial was laid out in a randomized complete block design with three replications. Generally all provenances were well adapted and performed well in their growth and significantly differ between genotip and environment. Varation exist in height, root collar, survival and biomass. North provenance planted at SPF Jeli showed the highest survival and height incement value followed by Mata Ayer ; Selandar and FRIM HQ.

Based on the results of this study, M.tanarius is a promising species but futher study need to be futher explored on the genetic studies.
