Effect of lime mine spoil based potting media on the growth performance of different tree species under nursery conditions

摘要

This study evaluated the effect of different combinations of lime mine spoil:forest soil (1:0, 1:1, 2:1 v/v), lime mine spoil:forest soil:farmyard manure (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. The experiment was carried out following randomized complete block design with three replications during 2002 in Himachal Pradesh, India. Results showed that the combination of lime mine spoil:forest soil:FYM in the ratio of 1:2:1 (v/v) was the most effective in terms of 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.
