Cultivation of Azolla.About Azolla Cultivation:- What is Azola? Well, it is nothing more than a free-floating fern consisting of a short, branched, floating, root-bearing stem that hangs underwater. It is a forage grown on water. Why is the cultivation of Azolla increasing and becoming popular? Because, Azolla has many nutritional benefits when compared to other forages. In addition, it also has the property of nitrogen fixation in rice fields. This is the reason Azolla is used as a popular biofertilizer and green manure in rice fields. This blue-green algae grows symbiotically with this fern and is responsible for nitrogen fixation in the rice crop. Where can it be grown? It can be grown in ponds, ditches and rice fields of warm temperate and tropical regions around the world. Azolla fodder is an excellent alternative feed supplement for livestock, poultry and fish. This is a benefit to dairy farmers because; It greatly reduces feed costs and leads to increased milk production. Although there are many species of Azolla, “A. pinnata” is popular among them. When it comes to nutritional value, Azolla is high in protein, amino acids, vitamins, and minerals (such as magnesium, calcium, phosphorus, and potassium). Azolla is a high yielding plant and it doubles its biomass in a period of 4-10 days, depending on conditions and yields can reach 8-12 tons/ha in Asian rice fields. Let us talk more about developing Azolla in this article.Azolla’s surname:- Salviniaceae family.

Azolla easily grows in the wild and can even be grown in controlled environments such as greenhouses and greenhouses.
Azolla can be grown in bulk, if required, and used as a green manure during both Kharif and Rabi seasons.
Azolla can fix atmospheric CO2 and nitrogen to form carbohydrates and ammonia, respectively. After decomposition it adds available nitrogen to the soil.
Azolla dissolves Zn, Fe and Mn and supplies them to rice plants in the field.
Azolla helps control weeds and suppresses weeds like Chara and Nitella in rice fields.
In a natural way, Azolla secretes plant growth regulators and vitamins which are essential to enhance the growth of rice plants.
Azolla helps to increase yield and quality of crops.
Azolla reduces the rate of water evaporation from irrigated rice fields.
When used as a supplement in dairy farming, it helps to increase milk production.

Azolla is shade-loving and requires light (30 to 50% of the light needed for its growth) for photosynthesis. As we know (Azolla) is a water based crop, one needs to ensure enough water to grow crops. There should always be at least 5 inches of water in the pond for Azolla to grow properly. Azolla grows well where the optimum/ideal temperature range is 20°C to 35°C. Temperatures higher than 36°C will severely affect Azolla multiplication. For better yield and quality of Azolla, it requires a pH value of water between 5.0 and 7.0 and relative humidity between 80 and 90%. Too many acidic or alkaline conditions have a negative effect on the growth of the Azolla (fern). When it comes to nutrient requirements, Azolla absorbs nutrients from water and phosphorus is the most important element. Typically, 20 to 25 ppm phosphorus In water is optimal. It is also necessary to apply micronutrients that can improve the multiplication and development of Azolla.Azolla in the Rice Fields.Growing Azolla:- To produce Azolla, it requires a shallow pond. Let us discuss more about Azolla growing in freshwater ponds.

The location of the pond in the cultivation of Azolla: The location of the pond plays an important role in the cultivation of Azolla. Make sure you have a location that you can monitor regularly. As this requires a good water supply, choose a location near a good water source. Basically, Azolla prefers partial shade, so one should choose a location with partial shade or partial shade to cover it up. This partial shade helps Azolla grow better and prevents water evaporation. Make sure the bottom of the pond is free of sharp rocks or spikes that could damage or puncture the pond bottom sheet.
Pond construction in Azolla cultivation: The size of the pond varies among farmers and is largely dependent on how much Azolla is expected to provide to livestock. In the case of small growers, you can go 6 feet x 4 feet to grow Azolla. This can produce 1 kg of supplementary feed/day. The pond needs to be cleaned and leveled. Use bricks to build the side wall of the pond (You can even use a raised embankment with excavated soil). Place durable plastic panels on the bottom of the pond and secure all sides of the panels by placing bricks on the side walls. Ponds also need to be covered with nets to prevent leaves and other debris from falling into the pond. This net also provides much needed partial shade in growing Azolla. To secure this net, place a wooden stake or bamboo stick on the pond wall. Place stones or bricks on the edges to secure the plastic sheet and grid.
Growing (Produce) Azolla: Mix clean soil with cow manure and water and spread it evenly throughout the pond. To cover a 6 foot X 4 foot long pond, 1 kg of fresh Azolla is required. Apply this culture uniformly in the pond. Make sure there is at least 5 to 6 inches of water depth in the pond. In order for Azolla to grow quickly, you can water it with rainwater during the monsoon season. Another important factor to consider in growing Azolla is not to allow high salt content in pond water which could adversely affect Azolla growth. If you are growing Azolla, you are better off testing the alkalinity and acidity of the water.
Pond maintenance in Azolla cultivation: To ensure better growth of Azolla, apply 1 kg of cow manure and 100 to 120 grams of superphosphate once every 2 weeks. Make sure to remove weeds that form in the pond regularly. The pond should be emptied once every 6 to 8 months and Azolla planting should be restarted with new culture medium and soil.
Harvest and Feed Azolla Cultivation: Usually, Azolla will be ready for harvest in 2 to 3 weeks after stopping culture in the pond. Azolla can be harvested daily after it is fully grown. Plastic sieves should be used to collect biomass from the pond surface. One can obtain an average of 1 kg of fresh Azolla per day from a pond size of 4 feet x 6 feet. Harvested Azolla can be fed directly or mixed with nutrients and for livestock such as cattle (dairy cows), sheep, goats, pigs, poultry and rabbits. Dried Azolla can also be used as fodder for livestock. Before feeding Azolla to cattle, the Azolla must be washed with fresh water. Dairy farmers are reaping high profits by avoiding feed costs and this has also been shown to increase milk yield. To get used to the taste of Azolla, it is better to feed it with concentrate in the early stages.

Azolla Horticulture Economy:- The cost of preparing a 6-foot X 4-foot pond depends on labor and other factors such as bricks (if bricks are used to build the edges of the pond). In general, the cost of Rs.2000 for this pond includes plastic sheeting. A farmer can get a net profit on Rs. 10,000 per year from additional milk production and reduced use of forage concentrates.Limitations in farming Azolla:- High summer temperatures, extreme lower temperatures, water scarcity and low humidity, and poor water quality make it difficult to grow Azolla.Conclusion: – Cultivation of Azolla is an excellent choice for farmers who want to fix nitrogen in rice fields and save on additional feed costs in livestock.
