Abstract
Nanotechnology offers a promising solution to soil degradation and environmental pollution caused by traditional agrochemical practices, enhancing crop productivity and nutrient-use efficiency at lower doses. The present study investigated the effect of nanoparticles (NPs) on the growth enhancement potential of plant growth-promoting bacteria (PGPB). Bacteria from tomato
rhizospheric soil were isolated and characterized for growth promotion. Magnesium oxide nanoparticles (MgONPs) and zinc oxide nanoparticles (ZnONPs) were synthesized using Azadirachta indica and Moringa oleifera leaves, respectively. The nanoparticles' effect on PGPB growth was evaluated by culturing them on potato dextrose agar (PDA) supplemented with different concentrations of NPs (100, 75, 50, and 25, and 0%). The number of colonies forming units were counted after 2 days of incubation
