Abstract:
Arbuscular mycorrhizal fungi (AMF) and rhizobia are important microbial partners that help legumes absorb nutrients and fix nitrogen. Groundnut (Arachis hypogaea), a leguminous crop, is largely reliant on symbiotic partnerships to grow, particularly in phosphorus (P)-deficient soils. This study looks at the effects of AMF inoculation, rhizobial symbiosis, and accessible soil P on groundnut nodulation and growth in Maharashtra's Niphad and Yeola regions. Soil samples from nine farmer farms with variable P availability were examined to better understand the interplay of AMF, rhizobia, and soil P in nodule formation and plant growth. The study found a significant positive connection (R²=0.98) between accessible soil P and nodule number. Phosphorus addition considerably increased the number of nodules, shoot dry weight, and nitrogen content. Inoculation with Glomus intraradices, a commonly employed AMF species, improved nodule formation and plant growth, though to a smaller amount than phosphorus addition. These findings are consistent with recent research demonstrating that AMF can partially replace phosphorus fertilizer by increasing nutrient absorption and facilitating nutrient cycle. Furthermore, rhizobia were found to interact synergistically with AMF, improving nitrogen fixation and overall plant health. The study emphasizes the need of integrated nutrient management, which includes both microbial inoculants and fertilizers, to boost legume productivity, particularly in low-P soils, and offers long-term ways to optimizing groundnut yields in emerging agricultural systems.
