Abstract

The environmental impact is likely the most critical concern, as it poses a threat to various ecosystems, food supplies, and farming, affecting humans, animals, and plants. However, many agricultural practices heavily depend on chemical fertilizers, which are cost-effective for farmers but have detrimental effects on human health, animal well-being, and the environment. Additionally, environmental stresses can significantly limit plant growth and yield, resulting in low crop productivity and jeopardizing global food security. Introducing plant growth-promoting endophytic bacteria (PGPEB) in mungbean crops offers an eco-friendly alternative to chemical fertilizers, helping to alleviate abiotic stress and enhance growth. In this study, 45 endophytic bacteria were isolated using Tryptone soya agar medium and screened for various plant growth-promoting activities. The highest nodulation, grain yield, nitrogen uptake by mungbean plants was observed when E13 was co-inoculated with standard Rhizobium (MB703) and phosphate solubilizer (P36) and similar trend was found with phosphorus uptake during the Summer and Kharif seasons, respectively, was also recorded with the co-inoculation of E13 with standard Rhizobium MB703 and phosphate solubilizer P36. The study concludes that using plant growth-promoting endophytic bacteria, particularly E13, can enhance mungbean crop productivity in a more economically and environmentally sustainable manner, thus contributing to increased global agricultural production.
