Inoculation of Azospirillum has significant positive effects on the growth characteristics and pigments in seedlings of Jatropha curcas. The bacterial inoculation significantly increased the shoot length by 44.85%, primary and secondary root length by 39.3% and 37.5%. Among the bacterial species, Azospirillum lipoferum enhanced the root and shoot biomass by 24.01% and 15.04% and leaf area by 28.57% than in control. Hence, the free living, nitrogen fixing Azospirillum lioferum can be used as a biofertilizer raising vigorous seedling of Jatropha curcas under nursery and field conditions.
