ABSTRACT

The study was conducted to determine the effect of different Rhizobium isolates, soil pH and moisture levels on growth of three provenances of Acacia auriculiformis under glass house conditions. The Papua New Guinea (PNG) provenance inoculated with R 2 rhizobial isolate at pH 5.5 and moisture level less than field capacity recorded maximum dry weight (1.057 g plant −1), nodule number (5.607) and total nitrogen content of plant (4.967 mg plant −1) when compared with Queensland and Northern Territory provenances. Hence, there is a considerable potential for introducing PNG provenance inoculated with R 2 rhizobial isolate in acidic soils of Kerala.
