This study was conducted to investigate the effect of nitrogen and phosphorus fertilizer on yield of Graham stylo (Stylosanthes guianensis cv. Graham) in Ban-thon soil series at Narathiwat Animal Nutrition Research Center, Narathiwat Province, during April 1996 to March 1998 (2 years). The experimental design was 4*4 factorial in randomized complete block with 4 replications. Factor A consisted of 4 nitrogen fertilizer rates viz 0, 10, 20 and 30 kg.N/rai/year and factor B was 4 phosphorus fertilizer rates viz 0, 10, 20 and 30 kg P2O5/rai/year. The result of this experiment indicated that average dry matter yield and protein yield of Graham stylo were highest (517.1 and 98.7 kg/rai/year) when applied nitrogen fertilizer 30 kg. N/rai/year with phosphorus fertilizer 20 kg P2O5/rai/year, different higher than other rates of nitrogen and phosphorus fertilizer (P LT 0.05). For forage nutritive value, percentage of crude protein when applied nitrogen fertilizer 20 kg N/rai/year with phosphorus fertilizer 30 kg P2O5/rai/year (19.6 percent) was higher than when applied nitrogen fertilizer 30 kg N/rai/year with phosphorus fertilizer 20 kg P2O5/rai/year (19.2 percent). The increased of nitrogen and phosphorus fertilizer rate had not affected ADF, cellulose and lignin content of Graham stylo, but phosphorus content was increased when applied phosphorus fertilizer which higher rate. The optimum rate of nitrogen and phosphorus fertilizer for Graham stylo in Ban-thon soil series were 30 kg N/rai/year and 20 kg P2O5/rai/year.
