Effect of Spirulina platensis in salt-stressed Phaseolus vulgaris L.

Foliar applications of S. platensis (100 mg/l) as eco-friendly biofertilizers and biostimulants have been found to enhance the growth, photosynthetic capacity, and total yield production of salt-stressed Phaseolus vulgaris plants. Simultaneously, they help reduce DNA damage and ROS-induced oxidative damage. The growth promotion induced by S. platensis can be attributed to its rich nutrient content, bioactive molecules, and phytohormones, which effectively scavenge ROS and alleviate their adverse effects by regulating metabolic processes in plants. These findings highlight the significant potential of algal extracts in modern horticulture and agriculture, as they offer nutritional benefits, ease of use, safety, and affordability, making them an excellent solution for mitigating salinity hazards.
