Abstract

Phosphate solubilizing bacteria (PSB) is an environment friendly and cost-effective approach as an alternative strategy to reduce chemical fertilizers usage. Phosphate solubilizing bacteria with multiple beneficial characteristics are important to increase the effectiveness of the inoculated host plant. Due to said interest the previously characterized PSB strain Chryseobacterium sp. PSR 10 was used to evaluate the effectiveness of the strain on finger millet (Eleusine coracana var. VLM-149). Finger millet is the third most important millet, next to sorghum and pearl millet. To evaluate the efficacy of the microorganism the pot experiments were designed with sterilized and unsterilized soil system. Seed inoculation of Eleusine coracana (finer millet) by Chryseobacterium sp. PSR 10 showed better plant growth promotion and increased plant growth agronomical parameters, chlorophyll content and nitrate reductase activity in both the soil systems. The better performance of the bacterium Chryseobacterium sp. PSR 10 was attributed to its greater P solubilization activity and positive correlation with plant growth promotion of finger millet. Furthermore, the result of the present study suggested that it is might be possible to select, bacterial strain Chryseobacterium sp. PSR10 as a good phosphate solubilizing bioinoculant which can be exploited as PSB.
