Effect of Phosphate Rich Organic Manure (PROM) along with Pseudomonas on growth and yield of rabi groundnut

Groundnut (Arachis hypogaea L.) is an important oilseed crop whose productivity is largely constrained by the limited availability of phosphorus (P) in Indian soils. Phosphate Rich Organic Manure (PROM), when integrated with P-solubilizing microorganism, offers a promising strategy to enhance P availability and crop productivity. The field experiment was conducted during rabi 2024-25 at Agricultural College, Aswaraopet, to evaluate the effect of inorganics, PROM and Pseudomonas fluorescens on growth and yield of rabi groundnut. The experiment consisted of nine treatments laid out in a Randomized Block Design with three replications. Results indicated that combined application of 75% recommended dose of phosphorus (RDP) substituted through PROM + Pseudomonas fluorescens soil application @ 7.5 kg ha^-1 recorded significantly taller plants (30.6 cm), wider leaf area (1156.8 cm² plant^-1), maximum dry matter production (6847 kg ha^-1) and higher pod yield (2977 kg ha^-1), this was was statistically comparable with 100% RDF + Pseudomonas fluorescens and 100% RDF. The study demonstrated that integrating PROM with Pseudomonas fluorescens bacteria can partially replace chemical fertilizers while improving productivity in groundnut.
