“…The Azolla-Anabaena system contributes 1.1 kg N/ha/day; one crop of Azolla provided 20-40 kg N/ha to the rice crop in about 20-25 days [53]. Azolla is used as a biofertilizer in many countries, such as Vietnam, China, Thailand, and the Philippines [54][55][56]. Another benefit of using this biofertilizer is its metal tolerance ability; thus, can be applied to the heavy metal-polluted areas [57].…”

Continuous decline of earth’s natural resources and increased use of hazardous chemical fertilizers pose a great concern for the future of agriculture. Biofertilizers are a promising alternative to hazardous chemical fertilizers and are gaining importance for attaining sustainable agriculture. Biofertilizers play a key role in increasing crop yield and maintaining long-term soil fertility, which is essential for meeting global food demand. Microbes can interact with the crop plants and enhance their immunity, growth, and development. Nitrogen, phosphorous, potassium, zinc, and silica are the essential nutrients required for the proper growth of crops, but these nutrients are naturally present in insolubilized or complex forms. Certain microorganisms render them soluble and make them available to the plants. The potential microbes, their mode of action, along with their effect on crops, are discussed in this review. Biofertilizers, being cost effective, non-toxic, and eco-friendly, serve as a good substitute for expensive and harmful chemical fertilizers. The knowledge gained from this review can help us to understand the importance of microbes in agriculture and the ways to formulate these microbes as biofertilizers for sustainable crop production.

“…Azolla is a water fern that floats on the surface of fresh water ponds, rivers, and flooded fields in the tropics and subtropics of both the New and Old Worlds. Its size is typically 1-2.5 cm in diameter, but some species can achieve the size of 15 cm or more (Qiu & Yu, 2003).…”

At present, there is intensive attention for using natural materials as sustainable resources for bioactive compounds. An interesting aquatic fern that is extensively studied is "Azolla spp.". Azolla is a genus of aquatic ferns and small-leafed floating plants, native to the tropics, subtropics, and warm temperate regions of Africa, Asia, and the Americas (Mosha, 2018). It is a floating pteridophyte that is symbiotic with the cyanobacterium Anabaena Azollae (Yang et al., 2020). Azolla species were successfully used as a biofertilizer, animal feed, water purifier, biological herbicide and for concentration of nutrients and heavy metals from flood waters (Selvaraj et al., 2014). Azolla was also shown to be a source of bioactive secondary metabolites such as phenols, tannins, sugar, anthraquinone glycosides and steroids, and also rich in protein, vitamin and minerals (Selvaraj et al., 2013). Concerning Azolla spp. the current study overviewed: classification, distribution and important applications in different fields in many countries and in Egypt in particular.

Azolla is a free-floating water fern which in symbiotic association with cyanobacterium Anabaena azollaefixes the atmospheric nitrogen. Nitrogen fixing ability of cyanobacterialsymbiont varies between 30 and 60 kg N ha−1 which designates Azolla as an important biological nitrogen source for rice ecosystem. Inoculation of Azolla is an alternative and sustainable source of nitrogen to increase the rice productivity and it also can decrease the use of synthetic fertilizer. A number of past researches prove that Azolla has been used as apotential biofertilizer for rice production. Azolla is either incorporated in the soil before rice transplanting or grown as a dual crop along with rice. The objective of this paper is to provide a brief account of importance as well as developments in the utilization of Azolla-Anabaena system in agriculture, mainly rice production.
