Arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with the roots of nearly all land-dwelling plants, increasing growth and productivity, especially during abiotic stress. AMF improves plant development by improving nutrient acquisition, such as phosphorus, water, mineral uptake. tolerance resilience to stressors drought, salt, heavy metal toxicity. These benefits come from arbuscular interface, which lets fungal partners exchange nutrients, signalling molecules, protective chemical compounds. Plants' antioxidant defence systems, osmotic adjustment, hormone regulation are also affected infestation. responses promote performance, photosynthetic efficiency, biomass production in stress conditions. As a result its positive effects on soil structure, cycling, carbon sequestration, contributes maintenance resilient ecosystems. The AMFs ecological stability species- environment-specific.

In soilless cultivation, plants are grown with nutrient solutions prepared mineral nutrients. Beneficial microorganisms very important in plant nutrition. However, they not present culture systems. this study we investigated the impact of introducing Plant Growth Promoting Rhizobacteria (PGPR) as an alternative to traditional fertilizer hydroponic floating lettuce cultivation. By reducing fertilizers at various ratios (20%, 40%, 60%, and 80%), replacing them PGPR, observed remarkable improvements multiple growth parameters. Applying PGPR led significant enhancements weight, leaf number, area, dry matter, chlorophyll content, yield, uptake soilles lettuce. Combining 80% demonstrated a yield that did significantly differ from control treatment 100% fertilizers. Moreover, application improved essential concentrations enhanced human nutritional quality, including higher levels phenols, flavonoids, vitamin C, total soluble solids. has potential sustainable substitute for synthetic leading environmentally friendly nutritionally enriched farming.
