A Primer on Azolla Production & Utilization in Agriculture Paperback – January 1, by M. Manzoor Khan (Author)Author: M. Manzoor Khan. The utilization of Azolla has remained limited in agriculture due to its sensitivity to high temperatures, light intensity, composition of growth medium and difficult production technology.

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.

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. 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. Use of Azolla in Agriculture - Azolla is a native water plant with some seriously exciting attributes for anyone looking to develop closed-loop cycles, which holds the promise of providing a sustainable feed for livestock.

Azolla is an excellent aquatic green manure plant, and was until recently used extensively in Vietnam, China and other parts of Asia in rice paddies, where it would cover.

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.

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. 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. In this book a scientific and management framework is provided for the use of azolla in agriculture, especially in the developing world. The book, which is based on Chinese, Vietnamese and Western literature, emphasizes the usefulness of azolla as a green manure for rice.

Some of the directions that exploitation of azolla may take are discussed. 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. Advances in Agricultural Microbiology is a collection of papers about the progresses in the field of agricultural microbiology.

The said papers are contributions of different experts in related fields. The book is divided into three sections. Section A covers topics related to the role of microorganisms in the mobilization of nutrients for plant growth such as the relationship of microbial.

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, ).

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. The grain yields were, and t/ha for the Azolla plus N-fertilizer, 60 kg N/ha, Azolla only and the control plot respeectively.

(Ghana Journal of Agricultural Science,29(2): ). Azolla is naturally found in ponds, ditches and wetlands of warm temperate and tropical regions throughout the world. It requires light for photosynthesis and grows well in partial shade. Generally, Azolla needs 25 to 50 per cent of full sunlight for its normal growth.

Water is the basic requirement for the growth and multiplication of Azolla. 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   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.

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 beneficial effect of Azolla in enriching the rice paddies with fixed nitrogen and thus enhancing yield has been known for centuries (Fogg et al., ; Watanabe and Liu, ).

Historically use of Azolla in China dates back to the record of Ming dynasty (AD –) agricultural book (Lumpkin and Plucknett, ).

Livestock feed: Azolla contains very high proteins, amino acids, vitamins (vitamin A, vitamin B12, beta-carotene) and minerals, so it is the excellent nutrient feed for livestock. factories. The book written by Jia Ssu Hsieh in A.D describes the cultivation and use of Azolla in rice fields.

In India, Singh and co-workers popularized the use of Azolla in rice cultivation []. At present many progressive farmers and non-governmental organizations are employing Azolla as an invaluable input in agriculture and some of.

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., Azolla (Azolla sp.) is an aquatic fern consisting of a short, branched, floating stem, bearing roots which hang down in the leaves are alternately arranged, each consisting of a thick aerial dorsal lobe containing green chlorophyll and a slightly larger thin, colourless, floating ventral lobe.

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. Cool weather is a key to successful Azolla utilization. Among nutrients, P is most important for azolla.

Since Azolla floats, it is not able to extract P from soil, thus its growth is often constrained by insufficiency of P if P is not applied into the flood water. The economics of Azolla use is very important.

The technology is labor intensive. Azolla is one of the world's fastest growing aquatic macrophytes, with a doubling time of only days (Taghi-Ganji et al., ). 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. 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.

Feeding of azolla in poultry birds improves the weight of broiler chicken and increases the egg production in layers. Hence the azolla can be used as unconventional high potential feed resource for non-ruminants.

Above all, for the best performance diets of pullet chicks can be formulated with inclusion of azolla up to 10 per cent. ADVERTISEMENTS: In this article we will discuss about the production of various bio-fertilizers.

Production of Bacterial Bio-Fertilizer: With day-by-day increasing the population, especially in developing countries like India, the stress on agriculture is also increasing continuously.

With the development, the land area under farming is not increasing but is further decreasing, this has. Zhang ZhuangTa et al., In: IRRI, Azolla utilization: Proc.

Workshop on Azolla use, Fuzhou, Fijian, China, Manila. 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.
