Isolation, Characterization and Inoculum Formulation of Nodule Forming Bacteria of Kudzu (Pueraria phaseoloides (Roxb.)Benth.) for Coastal Sandy Land Conservation

Kudzu plantation (Pueraria phaseoloides) as legume cover crop is one of alternatives in coastal sandy land conservation. The crops are known to associate with a root nodule-forming bacteria (Rhizobium sp.) which give some benefits to nutrient cycling i.e. : atmospheric N2 fixing and play role as soil conditioner; soil Nitrogen enrichment; nutrient cycling; and increasing other nutrients availability. A research to study the isolation dan bacterial inoculum multiplication from wild kudzu root nodules, compatible isolates screening and selected isolates multiplication, and examining the form, amounts and most proper inoculum application method was conducted in Greenhouse and Laboratory of Microbiology in Yogyakarta province.
