Nut Boost: A formulation of Plant Growth Promoting Rhizobacteria as biofertilizer for enhancing groundnut yield
Technology Details:The consortium of Plant Growth Promoting Rhizobacteria (PGPRs) comprising of Pseudomonas gessardii BHU1 (PGPR1), Pseudomonas putida S1(6) (PGPR2) and Pseudomonas putida BM6 (PGPR4), was originally isolated at Junagadh from groundnut rhizosphere. These microorganisms are having multiple plant-growth promoting attributes like ACC deaminase (an indicator of plant growth promotion), phosphate solubilization, production of siderophore, antifungal metabolites, hormones, and ammonification traits. Besides, these PGPR isolates also exhibited solubilization of Zn and potassium (K) and exhibited antifungalactivities against major soil-borne fungal pathogens like Sclerotium rolfsii and Aspergillus niger. Subsequently, application of these organisms has been found to enhance growth, yield, and nutrient uptake in groundnut at Junagadh, in farmers’ fields, at multilocation in India, tested through AICRP(G) centres for three years and demonstration through FLDs with yield advantage of 16.5 to 18.1 % over the un-inoculated control. These PGPR isolates have been recommended for irrigated and rainfed groundnut cultivation in India on the basis of the performance.
Benefits of the technology:• Eco-friendly.• Improvement in soil health, nutrient mobilization and uptake like P, K, N, Fe, Zn, etc. (P, Zn, and K solubilizer).• Produces plant growth promoting substances like IAA and iron chelating substances like siderophore.• Control of incidence of soil-borne fungal pathogens in groundnut (stem and collar rot).• Compatible with seed treating chemicals like Bavistin (Carbendazime)/Thiram.• Very fast growing and ease in large scale multiplication.• Can also be formulated in talcum powder, liquid and in charcoal/peat.• Strains of the consortium are compatible to each other and co-culturing is possible.• Yield advantage up to 20%.• Liquid formulated “Nut Boost” has a shelf-life of more than one year at room temperature.• Can also be applied through irrigation water or through FYM or through dripsystem.• Useful for both irrigated and rainfed conditions
