A Primer on Azolla Production & Utilization in Agriculture Paperback – January 1, by M. Manzoor Khan (Author)Author: M. Manzoor Khan. Abstract. Azolla is a genus of small fern that is found in the temperate and subtropical regions. The ferns grow floating on the water surface and in rice fields.
It is well known that Azolla grows rapidly and can double its weight in a nitrogen-free medium within 3–5 days. Azolla ferns live in association with a blue-green alga Anabaena azolla which is located in cavities of the ferns Author: A.
El-Bassel, I. Ghazi. Abstract. The tiny aquatic fern, Azolla is an eukaryotic fern plant associated with a prokaryotic blue-green alga. InLamarck named Azolla as a genus under ein separated Azolla from Saliviniaceae and set up a new family,a German, Strasburger found a kind of blue-green alga which belonged to Nostocaceae, and was located in the Azolla leaf cavities Cited by: 8.
The A Primer on azolla production & utilization in agriculture book of Azolla has remained limited in agriculture due to its sensitivity to high temperatures, light intensity, composition of growth medium and difficult production technology.
A study on azolla cultivation was conducted in the coastal areas of the Villupuram district of Tamilnadu to analyse the reasons for adoption and non adoption of azolla cultivation by the dairy farmers.
The local NGO (REAL) promoted azolla cultivation to reduce the cost of milk production in six adopted villages in this district.
The NGO has selected a total of dairy farmers to cultivate. A primer on Azolla Production and. Utilization in Agriculture, UPLB, PCARRD and Initial chapters of the book discuss the history of diffusion research, some major criticisms of diffusion.
Azolla finds use in the agriculture sector as green manure for rice Farming; sometimes it is also used in wheat, maize, and broad beans Farming areas. It is observed that production increases by 20%. Dry Azolla is used as livestock feed because of its high nutritional content and low lignin content.
Utilization of Azolla as fertilizer is indeed possible. Because, when calculated from the dry weight in the form of compost (dry Azolla) contains elements of Nitrogen (N) percent, Phosphorus (P) from to per cent and potassium (K) from 2 to percent. M.M.

It can be found on the surface of wetlands, ditches, ponds and rivers, native to the tropics, subtropics, and warm temperate regions of Africa, Asia, and the Americas (Costa et al., ) (Figure.
It has been intensively studied during the last few years for.

Dubeux Jr., Hichem. This book covers current knowledge on azolla management in rice production systems. It incorporates the experience of rice farmers in China and Vietnam, gained over many centuries.
Much of the information has not been available before outside of these countries. The first four chapters deal with the seven species of azolla, including its history, botany and physiology.
Green manure production of Azolla microphylla and Sesbania rostrata and their long-term effects on rice yields and soil fertility.
Biology & Fertility of So – Watanabe, I., Berja. Azolla pinnata growth performance experiments in different water sources were conducted from May until July at Aquaculture Research Station, Puchong, Malaysia. Four types of water sources (waste water, drain water, paddy field water and distilled water) each with different nutrient contents were used to grow and evaluate the growth performance of A.
pinnata. Azolla is a small aquatic fern with a branched stem and bilobed leaves. The roots that emerge from the stem help the plants to float on water. It is generally found floating on stagnant water. There is a small cavity on the upper most part of the leaf which houses as many as 80, blue green algae have the capacity to fix atmospheric nitrogen and make it available to azolla.

Evaluation of the nutritive value and free choice intake of two aquatic weeds (nephrolepis biserrata and spirodela polyrhiza) by west african dwarf goats.
Utilization of Azolla Microphylla as Feed Supplement for Crossbred Cattle 2. The Fern- Azolla Azolla (mosquito fern, duckweed fern, fairy moss, and water fern) is a small free floating aquatic fern native to Asia, Africa, and the America. Comparison of the nutritive value for laying hens of diets containing azolla (Azolla pinnata) based on formulation using digestible protein and digestible amino acid versus total protein and total amino acid.
Anim. Feed Sci. Technol., Historically use of Azolla in China dates back to the record of Ming dynasty (AD –) agricultural book (Lumpkin and Plucknett, ). It has been reported that cultivation of Azolla adds approximately tons of green biomass per hectare in a year under normal subtropical climate which is equivalent to kg N ( kg of urea.
Azolla, Azolla pinnata, is an aquatic fern belonging to the plant family Azollacea which is grown primarily as a fodder for is a small branching plant with a main stem and pinnate side branches. The side branches are longer at the base of the stem than at.
Azolla is a highly productive plant. It doubles its biomass in days or more, depending on conditions, and yield can reach 8–10 tonnes fresh matter/ha in Asian rice fields. t fresh weight/ha ( t DM/ha dry weight) has been reported for Azolla pinnata in India (Hasan et al., ).
Azolla filiculoides (red azolla) is the only member of this genus and of the family Azollaceae in. The earliest written record of Azolla was in an ancient Chinese dictionary called the Er Ya, which appeared about years ago. A Chinese book on agricultural techniques published by Jia Si Xue in a.d.
mentioned Azolla with respect to applied plant cultivation (Shi & Hall, ). When using azolla as a green manure, drain the taro lo‘i and roto-till it into the soil. Uses Organic N source Use azolla to add organic nitrogen (N) to the lo‘i sys-tem.
Estimates of how much N azolla can fix vary widely. Values reported in the literature range from 53 to kg/ha N fixed, with dry matter production between Summary of Invasiveness.
Azolla filiculoides is a small fern native to the Americas which has spread widely throughout the world by a variety of mechanisms, of which man has become the most significant (Lumpkin and Plucknett, ).Man has introduced A.
filiculoides into Europe, North and sub-Saharan Africa, China, Japan, New Zealand, Australia, the Caribbean and Hawaii. However, 2,4-DEE, a post-emergence herbicide, applied 30 DAT showed inhibitory effects on the growth and N 2-fixation of both Azolla and BGA. Inoculation of 20 t/ha of fresh Azolla 10 DAT produced maximum biomass within 20–25 days of herbicide treatments, depending upon the season.
The inoculation of 10 kg/ha of a dry mixture of BGA 10 DAT.

The use of agricultural systems that include dinitrogen fixing organisms appears to be an economically sound cultural practice. In the particular case of rice, biological nitrogen fixation by Azolla, blue-green algae (BGA), and heterotrophic microorganisms has long been recognized, in southeast Asia, as a fertilizer for rice culture.
Gaevskaya (, in Russian) gives a general review of the utilization of aquatic plants by animals. This book has been reviewed by Davis () who writes: “The author has done a great service by reviewing the world's literature.
She finds that the higher plants are consumed by a wide variety of animals including insects, birds and mammals. In Azolla Utilization.
