The investigation was conducted to examine the effects of aluminium on the soil micro-organism in the rhizosphere of pea genotypes with varying Al treatment.The experiment was layout in a factorial completely randomized design with the first factor comprised of 4 pea genotypes (2 tolerant and 2 susceptible each) and the second factor with 3 levels of Al treatment (control, 12 ppm and 24 ppm Al). The classical serial dilution technique was used for isolation of total bacterial and fungal population from the soil sample by spread plate technique on appropriate media. It was observed that aluminium caused marked influence on the bacterial and fungal population in the rhizosphere of pea genotypes. The fungal population showed a marked reduction at 24 ppm level of aluminium treatment in all genotypes except intolerant genotype (Kashi Samridhi) where an increase in the fungal population was observed. The bacterial population showed a positive relation with aluminium treatment. Low level of Al treatment showed an increase in the bacterial population in the rhizosphere of susceptible genotype but at a higher level of Al the rhizosphere of tolerant genotype had a higher bacterial population.
