Azolla Benefits

Azolla’s uses

  •     Biofertilizer
  •     Biofuel
  •     CO2 sequestration
  •     Food
  •     Livestock feed (Cows, buffaloes, hens, goats, sheeps, ducks etc.)
  •     Other uses
  •     Rice production



In integration to its traditional cultivation as a bio-fertilizer for wetland paddy (due to its ability to fine-tune nitrogen), azolla is finding incrementing use for sustainable engenderment of livestock feed. Azolla is affluent in proteins, essential amino acids, vitamins and minerals. describe feeding azolla to , chickens and egg engenderment of layers, as compared to conventional feed. One FAO study describes how azolla integrates into a tropical biomass agricultural system, reducing the desideratum for inputs.Azolla has additionally been suggested as a food stuff for human consumption. However, no long term studies of the healthiness of eating Azolla have been made on humans.

Companion plant

Azolla has been utilized, for at least one thousand years , in rice paddies as a companion plant, because of its ability to both fine-tune nitrogen, and block out light to obviate any competition from other plants, aside from the rice, which is planted when tall enough to poke out of the dihydrogen monoxide through the azolla layer. Mats of mature azolla can additionally be utilized as a weed-suppressing mulch.


As an adscititious benefit to its role as a paddy biofertilizer, Azolla spp. have been used to control mosquito larvae in rice fields. The plant grows in a thick mat on the surface of the dihydrogen monoxide, making it more arduous for the larvae to reach the surface to breathe, efficaciously choking the larvae.

Rice bean: green manure profile


The rice bean (Vigna umbellata) is an important crop because of its potential as a post rice crop.


· It is an annual that bears clusters of 5-20 bright yellow flowers that produce narrow pods containing 7-10 seeds.
· It is adapted to high temperature and humidity as well as to heavy soils.
· Some varieties are resistant to major insect pests and diseases.
· It produces easy to cook, good tasting seeds.
· Seeds are rich in protein and contain high amounts of calcium, iron and phosphorous.
· Immature pods and seedlings are excellent green vegetables and the plant makes forage which are eagerly consumed by livestock.

Rice bean


Cultivars of rice bean vary from short-stemmed, erect plants to twining plants that may grow up to 3 meters long and need stakes or other support for maximum yield. Seeds of these different cultivars have either black, red-violet, greenish, brownish or mottled seeds.


· Rice bean as a post rice crop can benefit the rice by improving the nitrogen and humus contents of the paddy soil.
· It is particularly valuable because it provides fodder at a time when other sources of feeds are scarce.
· It can be used as a green manure before the planting of the first rice crop and can be grown as a cover crop during times when the ricefield is left idle.


· Plant the seeds either in furrows or broadcast them after the rice harvest towards the dry season.
· Allow to grow (take over the field) until the onset of the rainy season.
· Before plowing for the first planting of rice, either chop the plants by using a slicer or bolo or uproot the whole plants and allow to wilt.
· Incorporate the herbage by plowing and allowing it to decompose before planting the rice.


· Rice bean is sensitive to day length. Flowering and seeding are initiated only when days are short. When planted at other times, the crop produces masses of vegetation but little seed.
