“…First, Azolla is known to absorb large amounts of heavy metals from contaminated wastewaters (Talebi et al, 2019). In addition, Azolla is used as a broiler ingredient in Bangladesh (Basak et al, 2002) and as a source of nitrogen fertilizer in rice production in Ghana, India, and China (Arora & Singh, 2003; Nyalemegbe et al, 1996; Singh & Singh, 1987; Yao et al, 2018). Recent genomic studies in Azolla species have provided invaluable insights into the evolution of land plants, cyanobacteria associations, and insecticide resistance (Güngör et al, 2021; Li et al, 2018).…”

Climate change is expected to be the primary cause of biodiversity loss in the future (Bellard et al., 2012;Velazco et al., 2019). Ecological Niche Models (ENMs) are the most frequently used technique for predicting the impact of future climate change on species' ranges and distributions. ENMs are used to forecast current and future environmental suitability and provide recommendations for identifying priority areas for protection (Tiamiyu et al., 2021), management, and conservation of species (Nzei et al., 2021), and restoration of habitats (Johnson et al., 2017;Zwiener et al., 2017). As the effects of climate change intensify, the capacity of a species to colonize new

A study was conducted to know the effect of Azolla pinnata collected from Hampapura of K.R. Nagar in Mysore district on seed germination, vigour index, biomass and yield of French bean. A total of four different treatments of earthen pots containing soil: sand: farmyard manure (2:1:1) amended with 10g (T1), 25g (T2), 50g (T3) and 100g (T4) of fresh Azolla biomass and pots amended with 10g (T0) of Factamphos served as positive control. Pots without any supplement served as negative control. 10 seeds of French bean variety ‘S 9’ were sown in each pot and normal agronomic practices were followed. Seed germination was determined after eight days of sowing, and after every 15, 30, 60 and 90 days of sowing, vigour index, biomass and pod yield were determined. The results of the study showed that, high percentage seed germination (81.66%) was recorded with the treatment incorporated with 25g (T2) of Azolla biomass followed by 10g (76.33%), 100g (76.00%) and 50g (72.66%) of Azolla biomass respectively. Minimum seed germination percentage of 64.66% and 65.66 % were recorded in respective negative and positive controls. Significant increase in seedling vigour (VI) was recorded in all the treatments compared to controls. Pod yield increased in T2 followed by T0, T1, T3, T4 and untreated respectively after 90 days of sowing. The study showed that Azolla could be used as a supplement for other pulse crops for increased biomass and overall yield of French bean.
