The tree growth performance study was conducted on coal mine spoil at Bina Project Singrauli in 2009. Data on height and diameter growth for tree species planted in monoculture and mixed culture experimental plots were recorded. Height/diameter ratio, tree volume, annual increment in height, diameter and tree volume were calculated for each species in monoculture and mixed culture. In monoculture leguminous tree species L.leucocephala and D.sissoo showed better performance in terms of height growth. In general the height, diameter and tree volume growth was better among non-legumes in T.arjuna and E.officinalis, but among legumes better performance were shown by D.sissoo, A.procera and P.pinnata in mixed culture experimental plots.
