Paper Title
Screening of Gibberellin Producing Rhizosphere Fungi

Abstract
The larger use of pesticide and synthetic fertilizer on the agricultural land brings negative impact to environment, plant and human health. Selecting potential gibberellin producing rhizosphere fungi is assumed as an effort to reduce synthetic fertilizer use on farms. In this study, we select potential rhizosphere fungi in producing gibberellin. Produced gibberellin concentration was various, at 3,95-4,69 µg l-1 which isolate ETR29 appears as the most productive one. Morphological identification result showed that isolate ETR29 is Aspergillus spp Keywords - Fungi, Giberellic, Rhizosphere.
