Abstract:
Food security is a global concern exacerbated by deficiencies in essential micronutrients, impacting human health, especially in low- and middle-income nations. This thesis addresses the prevalent issues of zinc and iron deficiency in Indian soils, focusing on their impact on crop growth, quality, and subsequent human health. A comprehensive exploration of iron and zinc-solubilizing endophytic bacteria as a potential solution for enhancing the nutrient content and bioavailability in finger millet (Eleusine coracana) is presented. The study begins with the isolation and analysis of 112 endophytic bacteria from three finger millet cultivars, selecting six based on their ability to solubilize iron and zinc salts. These isolates were characterized for plant growth-promoting attributes and adaptability to various abiotic stresses.
