Effects of phosphorus fertilization on growth and N accumulation in Azolla,hat ARA was reduced by 50 %. These observations indicate that a P level which produces good growth may not be sufficient for maximum N accumulation. Also, Watanabe (1987) reported that 6 split applications totalling 15 kg P.0. ha. resulted in equivalent growth and N accumulation by . as 6 split appl
