CONCLUSIONS
Soil conditions in post-mining (PT Timah Bangka)sandy with very low nutrient content
Rooting system constrain - could not enter to thedeeper area lateral root
An-organic fertilizer with NPK 30-50-10 g/ plant
required for plant establishment Manure 4 Kg/plant can help the plant during the
establishment
The best result combination of manure and an-organic fertilizer (NPK 50-75-15 g per plant)
Endofitic fungus improved plant growth duringestablishment
