Azospirillum species are plant growth-promoting bacteria whose beneficial effects have been assumed to be moderately due to production of phytohormones (including IAA and gibberellins). Forty isolates were isolated from rhizoplane of tuberose and five efficient Azospirillum isolates were screened based on in vitro IAA production and N2 fixation and used to study their beneficial effect on yield and nutrient content of Tuberose, which revealed that Azospirillum isolate ATR-39 was found significantly superior over other treatments.
