Response of two grasses to inoculation with Azospirillum spp. In a Bahamian soil

Abstract

Pearl millet (Pennisetum americanum) fertilized lightly with N and inoculated with a mixed culture of two Azospirillum species produced a significantly higher yield of dry matter than did the uninoculated control in a Bahamian limestone soil. Under similar conditions, the yield was higher for inoculated Guinea grass (Panicum maximum) than the control but the difference was not significant. The data suggest a beneficial N2 fixing association between pearl millet and the Azospirillum organisms.
