This study was conducted to investigate the effect of cutting interval and height on yield and chemical composition of Stylosanthes guianensis CIAT 184 in Ban-thon soil series at Narathiwat Animal Nutrition Research Center, Narathiwat Province, during October 1999 to May 2001. The experimental design was 3*3 factorial in randomized complete block with 4 replications. Factor A consisted of 3 cutting interval viz 40, 50 and 60 days and factor B was 3 cutting height viz 10, 15 and 20 cm from ground. The result of this experiment indicated that dry mater yield of S. guianensis CIAT 184 at cutting interval 50 and 60 days were higher than cutting interval 40 days, and protein yield at cutting interval 50 days was higher than cutting interval 40 and 60 days. For cutting height, the dry matter yield of S. guianensis CIAT 184 at cutting height 20 cm from ground was higher than cutting height 10 and 15 cm from ground. When cutting interval which shorter time, the percentage of crude protein was increased but the fiber content (NDF Cellulose and lignin) were decreased. The optimum cutting interval and height on yield and chemical composition of S. guianensis CIAT 184 in Ban-thon soil series were 50 days and 20 cm from ground.
