It can be utilized by rice in both wet and dry season. Azolla can be used in two ways: 1) as green manure incorporated before transplanting, and 2) as an intercrop incorporated after transplanting. In each case, about 500 kg (fresh weight) per ha is introduced into standing water in the rice field.
Why Azolla can be used as organic manure?
Azolla pinnata water fern is alternative organic materials that can be applied to organic rice fields, because of Azolla pinnata has higher nutritional value than manure. After the decomposition of organic nitrogen content is made available to the rice plants.
What is Azolla fertilizer?
Azolla is a nitrogen-fixing plant. Because flooded habitat is good for it, it is grown in lowland rice fields. It enhances the rice production by 30-60 kg N/ha, which is similar to the rice yield produced by 30-60 kilogram N/ha. It increases nitrogen mineralization in waterlogged soil when used as green manure.
Is azolla good for rabbits?
Azolla is one of the locally available aquatic pteridophyte which is a good source of protein and almost all essential amino acids. However, information on variations in various carcass traits of broiler rabbits due to feeding of azolla is scanty.
Is azolla good for pigs?
Azolla’s use as a feed for fish, swine and poultry was also tested and recommended by Alcantara & Querubin (1985) and Tran & Dao (1979) reported that one hectare of azolla can produce 540-720 kg of protein per month.
Does Azolla need fertilizer?
Azolla can provide nitrogen to crops but it lacks enough phosphorous to completely replace chemical fertilizers.
How do you make Azolla grow faster?
Slurry made of 2 kg cow dung and 30 g of Super Phosphate mixed in 10 litres of water, is poured onto the sheet. More water is poured on to raise the water level to about 10 cm. About 0.5 – 1 kg of fresh and pure culture of azolla is placed in the water. This will grow rapidly and fill the pit within 10 – 15 days.
Can Azolla grow on land?
Although Azolla can grow on wet mud surfaces or wet pit litters, it prefers a free-floating state. Azolla can survive within a pH range of 3.5 to 10, but optimum growth is observed in the range of 4.5 to 7. Optimum temperature for growth and nitrogen fixation depend on the species.
How do you make azolla grow faster?
Does azolla need soil?
A mixture made of cow dung, mineral mixture, soil and water should be added once in seven days. After every 60 days, soil is removed from the bed and another 15 kg of fresh fertile soil is added into the bed to avoid nitrogen build up and also provide nutrient to the azolla.
