Population data were transformed into log 10 cfu g dry soil ?1 .
Percentage data were arcsine transformed before analysis of
variance was carried out. To evaluate the effect of different
amendments on plant growth, nutrient levels and population
densities of PSB, data were subjected to one way analysis of
variance (ANOVA) and significant differences between means
were compared using Fisher’s protected LSD test at P = 0.05.
Superanova 1 (Abacus Concepts Inc., Berkeley, CA, USA) was
used for all analyses.
