Fluorescent Pseudomonas spp. comprise an important group of rhizosphere bacterial community affecting plant growth. Sorghum is an important fifth largest cereal crop in world. 75 fluorescent Pseudomonas spp. were isolated from diverse agro-ecosystems of India and evaluated for their plant growth promoting ability initially by paper cup method. Fourteen selected isolates were further evaluated under glass house conditions. Plants inoculated with bacteria showed higher growth and nutrient uptake than controls. Seedlings treated with selected isolate P17 showed highest root volume (0.3 cm3 ), shoot length (36.2 cm), dry mass (152 mg), leaf area (31 cm2 ), chlorophyll (23 spad units), carbohydrates (30%), phosphorus (1.3%), nitrogen (2.2%) and other nutrients. Among the evaluated isolates Pseudomonas sp. P17 strain was identified as a potential PGPR for nutrient uptake and plant gro.. View More»
