French marigold plants were treated with different biofertilizers to see how they affected growth and flowering. The best treatment included VAM and Azotobacter, resulting in taller plants with more branches and bigger flowers. These plants also bloomed earlier, had more flowers, and produced more seeds compared to other treatments. Overall, the biofertilizer combination of VAM 2.0 g/plant + Azotobacter 1.5 kg/ha showed the most significant improvements in plant growth, flowering, and seed production.
