“…The growth rate of Azolla in this study was slightly lower than the result of Hossain et al (2021) andda Silva et al (2022), who applied synthetic fertilizer in their research. However, it was higher than the results of research by Nordiah et al (2012), by growing Azolla only on the water without fertilizer, and those of Kösesakal and Yildiz (2019), with the application of Hoagland solution as fertilizer. This study further confirms that the requirement of various nutrition for Azolla production and it's availability in quail manure seem to match in order to grow Azolla under suitable environmental conditions.…”

Azolla (Azolla microphylla) is a potential livestock feed due to its fast-growing and relevant nutrient content. Quail farming generates manure as a by-product that can be used as fertilizer to support plant growth. This study aims to determine the dose effect of fermented quail manure on the growth rate of Azolla, as well as the nutritional content of the resulting Azolla biomass. The data were obtained through observation in 20 Azolla culture ponds according to the design method throughout the research for the Azolla growth rate parameters and laboratory tests to analyze manure and Azolla proximate content at the end of the study. The results showed that treatment of 50, 100 and 150 g m-2 of quail manure gave similarly good effects on the Azolla growth parameters, indicating that the application of quail manure can significantly increase the production of Azolla biomass in culture ponds. The resulting Azolla biomass from all treatments gave a value of 93% to 95% moisture content, 18% to 19% ash content, 36% to 42% protein, 20% to 37% fiber, 2.8% to 4% fat and 5% to 6% carbohydrates. Looking at the big picture, therefore, 100 g m-2 manure treatment is considered the most optimal among the rest. Based on the result obtained, this study can provide an overview of the dose of quail manure that can be used to support the growth of Azolla.

“…The 15% Hoagland solution achieved a comparable growth rate of 0.190 day −1 . This contrasted to the research of [33], in which the optimal growth rate of 0.124 day −1 was achieved using a full strength Hoagland solution. The lowest growth rate was 0.123 day −1 , which was achieved using the 1% Hoagland solution.…”

“…The increase in growth rate for the 60% humidity compared to the 75% humidity was 5.8%, 2.4%, 1.2%, and 4.4%. There were two growth studies that reported humidity values: one reported 60% to 70% [33] humidity and the second reported 55% to 70% humidity [34]. Both studies reported the lower growth rates of 0.124 day −1 and 0.100 day −1 , respectively.…”

Nitrogen pollution from agriculture is a major challenge facing our society today. Biological nitrogen fixation is key to combat the damage that is caused by synthetic nitrogen. Azolla spp. are ideal candidates for fast nitrogen fixation. This study aimed to investigate the optimal growth conditions for Azolla pinnata R. Brown. The growth conditions that were investigated included the growth medium type and strength, light intensity, the presence/absence of nitrogen in the medium, pH control, and humidity. Higher light intensities increased plant growth by 32%, on average. The highest humidity (90%) yielded higher growth rate values than lower humidity values (60% and 75%). The presence of nitrogen in the medium had no significant effect on the growth rate of the plants. pH control was critical under the fast growth conditions of high light intensity and high humidity, and it reduced algal growth (from visual observation). The optimal growth rate that was achieved was 0.321 day−1, with a doubling time of 2.16 days. This was achieved by using a 15% strength of the Hoagland solution, high light intensity (20,000 lx), nitrogen present in the medium, and pH control at 90% humidity. These optimised conditions could offer an improvement to the existing phytoremediation systems of Azolla pinnata and aid in the fight against synthetic nitrogen pollution.

“…Our result on the Azolla growth rate is comparable to that reported in the references. For example, Kösesakal and Yıldız [48] reveal that A. pinnata has a growth rate of 0.148 g.g -1 .d -1 and 0.120 g.g -1 .d -1 for A. caroliniana. In addition, [42] reports a higher growth rate of 0.162 to 0.214 g.g -1 .d -1 with the highest value for Azolla cultivated without fertilizer addition.…”

To maintain pond water quality, a large amount of wastewater is discharged. The wastewater degrades the environment and annoys nearby residents. This wastewater is the potential for growing Azolla microphylla, a valuable floating fern for different purposes. This research aims to observe the effect of water replacing period and mechanical aeration on the growth of A. microphylla and the wastewater quality. A 20-gram of A. microphylla biomass was inoculated in a plastic-layered wooden box (50×30×20cm) filled with catfish pond wastewater, and then designed treatments were applied for a 12-day experiment. A completely randomized design with two factorial arrangements was implemented. The first factor was the period of water replacement consisted of four levels: no replacement (E0), once in 2 days (E1), once in 4 days (E2), and once in 6 days (E3). The second factor was mechanical aeration consisted of three levels: no mechanical aeration (A0), 12-hour aeration (A1), and 24-hour aeration (A2). Parameters to be observed were Azolla biomass and water quality (temperature, pH, turbidity, and ammonium). The data set was analyzed using ANOVA followed by LSD multiple comparisons. Results revealed that interaction of the water replacing periods and the mechanical aeration significantly affected water quality (temperature, pH, turbidity, ammonium) but was not significant for the yield of A. microphylla biomass. The factor of water replacing period alone significantly affected the growth of A. microphylla. The E2 treatment was the most promising option, with a biomass yield of 804 g/m2 within 12-day cultivation.
