Azotobacter chroococcum has established its significance in crop production, plant nutrition, and soil fertility. As a free-living N?-fixing diazotroph, A. chroococcum markedly enhances crop production through biological nitrogen fixation and the secretion of growth-promoting substances. Being a beneficial soil bacterium, this genus synthesizes phytohormones and plant growth regulators—specifically auxins, gibberellins, and cytokinins—which possess stimulatory effects on plant development. In addition, it stimulates rhizospheric microbes, protects plants from phytopathogens, and improves overall nutrient uptake. Currently, Indian agricultural soil is increasingly deficient in micronutrients, largely due to the widespread reliance on chemical fertilizers for major nutrient supplementation and the inadequate conversion of agricultural waste into farm compost. To address this, the present study investigates the optimal industrial production of Azotobacter bio-inoculants in the presence of critical plant micronutrients. This research ultimately aims to guide the specific production of Azotobacter bio-inoculants targeted for micronutrient-deficient agricultural soils, aligning with soil health card recommendations and the Fertilizer Control Order (1985) amendments.
