Studies to evaluate the effect of different combinations of lime mine spoil: forest soil (1:0, 1:1, 2:1 v/v), lime mine spoil: forest soil: FYM (1:1:1, 1:2:1, 0:1:0 v/v), lime mine spoil: sand: FYM (1:1:1, 2:1:1 v/v) and lime mine spoil: sand: compost (1:1:1, 1:0:1 v/v) on performance of four tree species viz., Leucaena leucocephala, Eucalyptus hybrid, Acacia catechu and Bauhinia variegata were conducted in poly-bags of size 22" x 12" (LxB). The experiment was carried out following randomized complete block design with three replications during 2002. The results showed that combination of lime mine spoil: forest soil: farmyard manure in the ratio of 1:2:1 (v/v) was found to be most effective with regard to growth and biomass production parameters in all the four tree species. Leucaena leucocephala gave maximum values for height, collar diameter, shoot dry weight and total biomass followed by Eucalyptus hybrid, Bauhinia variegata and Acacia catechu. |
