Survival and Growth Pattern of Three Tropical Forest Plantations Raised on Coal-mine Spoils of Central India

Abstract

The present paper deals with the height and diameter growth in young plantations of the three native tree species (Albizia lebbek, Albizia procera, Tectona grandis) planted on mine spoil situated in tbe eastern section of Jayant Block of Singrauli coalfield in Madhya Pradesh, India. Highest survival rate was observed in the case of A. procera and the lowest in the case of T. grandis. Maximum specific height growth rate and specific diameter growth rate was exhibited by T. grandis whereas A.lebbek registered the minimum specific rate of increase in height and diameter. Aalysis of mean specific growth rates both for height and diameter indicated a decline with age in all the three species. However, the decline in the specific height and diameter growth rate of T. grandis was faster than in A. lebbek and A. procera
