Cultivation and uses of , in Egypt is well known that . grows rapidly and can double its weight in a nitrogen-free medium within 3–5 days... ferns live in association with a blue-green alga . which is located in cavities of the ferns’ lobes. The algae efficiently fix atmospheric nitrogen, and consequently improve the growth of the s

Estimation of nitrogen fixation in ,—rice association using ,N isotope dilutionlone or as a mixture, were studied in normal and sterilized soils. A total of 40 kg N fed. was applied as urea, . or . and urea in combination, to rice plants grown in pots. Urea or ., applied at equal rates of 40 kg N fed., were equally effective for increasing the dry mass of shoots and roots over

Ecological aspects of cyanobacteria from the rice fields of Corrientes (Argentina)rial fertilizers are scarcely available. In the rice fields of Corrientes, Argentina, these fertilizers are used abundantly, with an increase in yield but at the cost of ammonium and nitrate pollution in the local water supplies which are mainly from Paraná River..In order to avoid this nuisance, an

Some were due to a lack of knowledge about BNF systems in warm countries. Other difficulties were due to the interference of many yield-limiting factors other than nitrogen. But the main difficulty resul
