Abstract
Azolla, a genus of heterosporous aquatic ferns generally included in the Salviniaceae, is widely distributed in tropical and temperate fresh-water ecosystems. Members of the genus are capable of growth in environments deficient in combined nitrogen since they invariably contain an N2-fixing cyanophyte which can provide their total N requirements. The current interest and potential of these N2-fixing associations as an alternative N source in rice culture, as well as their long time usage for this purpose in the Far East, is well documented (Moore, 1969; Tuan and Thuyet, 1979; Liu, 1979; Singh, 1979; Rains and Talley, 1979; Talley and Rains, 1980; Watanabe et al., 1977).
