How will azolla help rice if they are grown together in field?

Azolla, a floating aquatic fern, can enhance rice cultivation by improving soil fertility and reducing the need for synthetic fertilizers. It has a symbiotic relationship with nitrogen-fixing cyanobacteria, which enriches the soil with nitrogen, promoting healthier rice growth. Additionally, Azolla provides shade, which can help suppress weed growth and maintain soil moisture. Together, they create a more sustainable and productive agricultural system.
