Azolla, A Low Cost Aquatic Green. Manure for Agricultural Crops. INTRODUCTION. The air we breathe is 79 percent nitrogen. Plants need nitrogen to make the proteins that allow them to harvest sunlight and carry on natural processes. Unfortunately, nitrogen in the air is in an inert N2 form that cannot be used by plants.
The nitrogen fixing aquatic pteridophyte Azolla has the ability to fix atmospheric nitrogen at cheaper and faster rates due to the presence of a symbiotic cyanobacterium Anabaena azollae. Because of this property it has been exploited widely as biofertilizer for rice plants. In addition to this it has several other uses such as

applications and future challenges of the use of Azolla as biofertiliser in Africa. In this continent, agriculture is the most important sector of economy and it employs 75 % of the labour force. The dwelling of fossil fuel reserves and the increasing costs of commercial nitrogen fertilisers implicate finding other alternatives, such
A study on Azolla cultivation and feeding to milch animals was taken up with about 110 farmers in Chitradurga district of Karnataka under NAIP Livelihood project. Feeding of Azolla @ 800 grams (fresh weight) on an average per day, improved the monthly milk yield by at least 10
Azolla is a floating pteridophyte, which contains as endosymbiont the nitrogen-fixing cyanobacterium Anabaena azollae. (Nostocaceae family). Widely cultivated in the Asian regions, Azolla is either incorporated into the soil before rice transplanting or grown as a dual crop along with rice. To examine the feasibility of its use

Azolla -Anabaena symbiosis - its physiology and use in tropical agriculture. I. WATANABE. 1. Introduction. Azolia is a water fern widely distributed in aquatic habitats like ponds, canals, and paddies in temperate and tropical regions. This plant has been of interest to botanists and Asian agronomists because of its symbiotic
also attracted the attention of livestock, poultry and fish farmers (Cagauan and Pullin,. 1991). In Asia Azolla has been long used as green manure for crop production and a supplement to diets for pigs and poultry. Some strains of Azolla can fix as much as 2-3 kg of nitrogen/ha/day. Azolla doubles its biomass in 3-10 days,
nitrogen/ha/ day; Azolla contains around. 27% crude protein and 10% carbohydrates on a dry weight basis (see Table). As a fish food, however,Azolla is an unknown quantity. The International Rice Research Insti- tute (IRRI) at Los Ba?os, Laguna, Philip- pines is investigating the use of Azolla in rice culture with a research
