- Abstract
- Indigenous acacia species are preferred in mine dump revegetation because of their ability to colonize hostile environments, enhance soil fertility and meet the livelihood and cultural needs of local communities. This study compared early growth performance of three indigenous Acacia species namely A. gerrardii, A. karroo and A. polyacantha established on Gold Mine tailings amended with top soil, sewage sludge, and compound fertilizer.Growth performance in height and root collar diameter (RCD) were measured monthly using a meter rule and a veneer caliper respectively and survival was determined at the end of a six-month period. A completely randomized block design with 12 treatments replicated three times was used. Survival and relative growth rates in height and RCD (RGRh and RGRd), were tested for significant differences among treatments through analysis of variance using SPSS Package.Overall, there were no significance differences (P>0.05) in survival among the Acacia species but variation in survival (P>0.05) was observed among amendments. Species growth performance also varied (P > 0.05) among amendment materials and across species. It was concluded all the three species can be used in revegetation of nickel mine tailings dumps under similar conditions.
