Plant Growth Promoting Rhizobacteria for Sustainable Production of Sugarcane and Rice

Sugarcane (Sacchraum officinarum L.) and rice (Oryza sativa L.) are important cash and staple crop in the world respectively. In today’s population explosion the lots of pressure on cropping land to mitigate the feed need of consumers with judicious use of chemical fertilizers without considering the health of soil and its sustainability. The rhizobacteria live region around roots (2-80 mm) of crop with divers, dynamic and complex microflora having capacity with direct and indirect beneficial effects on crop health by availability of different nutrient, siderophores, rhizo deposits, auxins and role with bioremediation. There are different types of bacteria is isolated from rhizosphere of sugarcane and rice having Bacillus, Rhizobium, comamonas, cyanaobacteria, Nodosilinea, Levinella and Pseudomonas genera with most efficient nitrogen producer, solubilizers of inorganic phosphate, potash and other macro and micronutrient. In rice microbiome as Levinella, Psudomonas Anaeromyxobacter, Arenimonas, Arthrobacter, Bacillus, Bellilinea Proteobacteria, Chloroflexi, Actinobacteria, Acidobacteria and cyanobacteria with strains of Nitrosomonas and Nitrobacter are further divided in vegetative and reproductive growth stage of rice crop. The article give brief idea about the large arena of them.
