Abstract

The use of plant growth promoting bacteria (PGPB) is an economically and environmental friendly alternative to the application of chemical fertilizers resp. pesticides in agriculture. To obtain novel bacterial strains that could be used for plant growth promotion (PGP) in the agriculture of Bolivia, plant associated bacteria derived from horseradish tree (Moringa oleifera), sorghum (Sorghum vulgare), sunflower (Helianthus annuus), and safflower (Carthamus tinctorius) were screened for direct and indirect in vitro PGP traits. Subsequently, most promising strains were selected for ad planta studies. According to in vitro experiments, out of 59 tested isolates, 19% were declared as diazotrophs, 41% as solubilizers of phosphorus, 10% were able to reduce the ethylene precursor 1-aminocy-clopropane-1-carboxylic acid (ACC), and 17% exhibited phytohormone (IAA) synthesis. Only a small proportion of rhizo …
