Production of Azolla in Different Condition and its Comparative Study

摘要

Azolla (mosquito fern, duckweed fern, fairy moss, and water fern) is a genus of seven species of aquatic ferns in the family Salviniaceae. They are extremely reduced in form and specialized, looking nothing like other typical ferns but more resembling duckweed or some mosses. Azolla is a highly productive plant. The study indicated Green Azolla to be a good source protein supplement with 22.3% crude protein fractions, high digestibility of dry matter and organic matter and rich in trace minerals thus could be used as an alternate protein supplement or as supplementary protein supplement to ruminants. The Azolla meal was easily digestible. The micro flora and micro fauna quantity in stomach of the domestic animals were increasing due to feeding of Azolla meal. Azolla can multiply very rapidly. Phosphorus is one of the most important and often limiting nutrients for Azolla growth. Phosphorus deficiency is indicated by smaller, less vigorous plants and May causes the plants to become pink to deep red and fragile and to develop very long roots known as Red Azolla. It may be good nutritional supplement as a feed to the domestic animals in drought area because for production of Azolla require minimum space and water.
