Application of Charcoal-Incorporated Organic Fertilizer and Charcoal• Incorporated Mycorrhiza Organic Fertilizer on the Growth Mediafor Shorea crysophylla Seedlings

This paper present research regarding the application of charcoal-incorporated organic fertilizer(OOF) and charcoal-incorporated organic fertilizer(CIMOF) lo the growth media for Shorea crysopllyila seedlings, which lasted separately but conrurrently far 6 month in the greenhouse. This research ainud to look into the effect of OOF and CIMOF mplfy!11ents on thegrowth responses i.e. weight and diameterof those seedlings. & suits revealed that the use of one tablet of CIMOF brought about significant effect on the height and diameter growths of Sborea crysopllyila seedlings, in that thereIJJQS an increase as much 4 3.9% the height and 4 9.3% the diameter as those of the control (without CIMOF). Meanwhile, the use of OOF seemed less effective lo inflictmch increase than that of CIMOF. The increase was only 33.65% and40.06%forheightand diameter, respectively It can be inferred that to enhance thegrowth of Sbores crysupilyila seedlings, it was s11.fficient by msten plqyingone tablet of CIMOF rather than the use of OOF. Further, the use of CIMOF tablet proved fl/Ore effective increasing the seedlingheight and diameter.
