  1. ASPERGILLUS NIGER “Plant Interaction with Aspergillus nige” How does Aspergillus niger affect plants?

  2. ENHANCEMENT OF NUTRIENT AVAILABILITY IN SOIL Aspergillus niger improves nutrient availability in soil by converting insoluble minerals into forms that plants can absorb. It releases organic acids such as citric and gluconic acid, which solubilize phosphorus and mobilize micronutrients like iron, zinc, and calcium. This process increases nutrient efficiency in the root zone, reduces nutrient fixation, and supports balanced plant nutrition, leading to better root development, improved growth, and higher crop productivity.

  3. ORGANIC ACID PRODUCTION AND ROOT ZONE ACTION Aspergillus niger produces organic acids such as citric and gluconic acid in the root zone. These acids lower soil pH locally, dissolve bound nutrients, and improve their availability to plant roots. This action enhances nutrient uptake efficiency, supports healthier root systems, and improves overall soil–root interaction. pH reduction Nutrient release Root efficiency

  4. IMPACT ON ROOT GROWTH AND NUTRIENT UPTAKE Aspergillus niger supports root growth by improving the availability of essential nutrients in the rhizosphere. Through nutrient solubilization and organic acid activity, it enables roots to access phosphorus and micronutrients more efficiently. This leads to stronger root branching, better root surface development, and improved nutrient absorption. Enhanced nutrient uptake supports healthier plant establishment, increased stress tolerance, and steady growth throughout the crop cycle.

  5. INFLUENCE ON PLANT GROWTH, HEALTH, AND YIELD Growth stimulation Stress tolerance Yield improvement Aspergillus niger positively influences plant growth by improving nutrient availability and supporting efficient root function. Better access to phosphorus and micronutrients promotes balanced growth, stronger plant structure, and improved physiological activity. Healthy nutrient uptake helps plants withstand stress conditions, leading to uniform development, improved crop vigor, and higher yield potential under suitable soil and management conditions.

  6. Aspergillus niger shows beneficial effects in well-managed soils by improving nutrient availability and supporting plant growth. Under proper moisture, aeration, and nutrient balance, it acts as a helpful soil microorganism. However, under poor soil conditions, high stress, or improper storage, it may contribute to plant damage or post-harvest spoilage. Its impact depends largely on environmental conditions and agricultural management practices. BENEFICIAL VS ADVERSE EFFECTS UNDER DIFFERENT CONDITIONS

  7. PRESENTATION CONCLUSION Aspergillus niger plays an important role in agriculture by enhancing nutrient availability, supporting root development, and improving overall plant growth and yield under suitable conditions. When managed properly, it functions as a beneficial soil microorganism that contributes to soil health and crop productivity. However, its effects depend on environmental and management conditions, making proper application and handling essential for achieving positive agricultural
