Summary
With global agriculture increasingly challenged by water scarcity and the need to reduce chemical inputs, plant growth-promoting bacteria (PGPB) offer a sustainable means to enhance crop productivity and stress tolerance. By improving nutrient availability and uptake efficiency, PGPB can reduce the reliance on synthetic fertilizers without compromising crop yield or quality, delivering both economic and environmental benefits. Despite this potential, most existing studies have focused on short-term effects in seedlings or plantlets under laboratory conditions using artificial substrates, with relatively few investigations addressing the full crop life cycle under realistic field conditions. In this study, we assessed the effects of two rhizosphere-derived bacterial isolates from arid grass
