Phosphorus (P) availability and mycorrhizal connections are critical in increasing agricultural production by improving nutrient absorption and stimulating plant development. This study looks at the interactions between phosphorus treatment and mycorrhizal inoculation on cotton (Gossypium hirsutum L.) in a controlled greenhouse environment. The experiment had two phosphorus levels (0 mg P₂O₅ kg⁻¹ and 50 mg P₂O₅ kg⁻¹) and three mycorrhizal treatments: control (no inoculation), indigenous mycorrhiza, and Glomus clarum. Plant height, stem diameter, root and shoot morphology, dry matter yield (DW), and phosphate absorption were all evaluated thoroughly. In addition, Mycorrhizal Dependency (MD) was measured to determine the level of plant reliance on mycorrhizal connections. The study found that combining phosphorus with mycorrhizal inoculation significantly boosted several growth indices, including root shape, stem diameter, and dry matter production. Glomus clarum mixed with phosphorus treatment had the highest dry matter production (47.38 g pot⁻¹). Mycorrhizal reliance was discovered to be inversely related to phosphorus availability, with non-phosphorus-treated pots having higher dependency (11.3%) than phosphorus-treated pots (8.1%). These findings emphasize the synergistic effects of combining phosphate delivery with mycorrhizal inoculation to boost cotton growth, particularly in phosphorus-deficient soils. The study sheds light on sustainable agricultural techniques, particularly the potential of mycorrhizal fungi as bio-inoculants for optimizing nutrient management and increasing crop yields.
