Three molar concentrations were tested: 10-7 M, 10-8 10-9 respectively. Five parameters assessed: optical density, turbidity, biomass production, chlorophyll fluorescence, pigment concentration. Results after 15 days culturing revealed that treatments significantly enhanced production (13.53% at M), synthesis, photosystem II activity (14.38% M).

North America, South America Oceania fewer contributions. Additionally, institutions Pakistan, India Egypt rank as most productive this topic. Saudi Arabia stands out highest percentage international collaboration, at 91.7% between countries 100% among institutions. The findings reveal that significantly ability withstand abiotic stress, optimize nutrient uptake, overall health. Research is transitioning traditional organic methods microbial inoculants advanced biostimulant formulations, improved management, reduced environmental impact. However, gaps remain, particularly understanding combined effects multiple long-term impact soil synthesis trends lays groundwork advancing production, supporting food security agricultural resilience amidst challenges.

Biofertilizers derived from microalgae are increasingly used as promising materials for improving crop growth and development, producing fewer catastrophic environmental effects. Hence, the large-scale production of eco-friendly broad-spectrum biofertilizers is mandatory. Therefore, this study was designed to examine potential efficacy isolated algae strains, such Spirulina platensis, maxima, Chlorella vulgaris, improve development Pak Choi. A completely randomized design (CRD) carried out, with five replications six levels (0, 0.5, 1.0, 1.5, 2.0, 2.5 g) each microalga biofertilizer, using Choi test plant. Treatment found increase Choi’s overall performance, biochemical nutritional composition. The application platensis maxima at 2 g a biofertilizer showed significant (p < 0.05) positive impacts on above- below-ground biomass, photosynthetic parameters, composition, attributes different parts tissues.
