Effect of plant spacing on yield and chemical composition of 2 varieties of Brachiaria humidicola on Rangae soill series was studied at Tambon Karuwarnearn, Muang District, Narathiwat Province. The experiment had been done during November 1999 to August 2001. A 2*3 factorial arrangement in randomized complete block with 4 replications was used. the Treatment consisted of 2 varieties of B. humidicola (B. humidicola and B. humidicola CIAT 26427) and 3 plant spacing viz 25*25, 50*50 and 50*75 cm. The result of this experiment indicated that dry matter yield and protein yield of B. humidicola were 2,571 and 168.7 kg/rai/year higher than B.humidicola CIAT 26427 (1,844 and 138.4 kg/rai/year). For forage nutritive value, percentage of crude protein and calcium of B. humidicola CIAT 26427 (7.48 and 0.34 percent) were higher than B. humidicola, but NDF, ADF and hemicellulose were lower (P LT 0.05). For effect of plant spacing, the dry matter yield and protein yield of 25*25 cm plant spacing were 2,522 and 175.3 kg/rai/year higher than 50*50 and 50*75 cm plant spacing (P LT 0.05). But all spacing had not effected CP, NDF, ADF, Hemicellulose, Cellulose, Lignin, Calcium and Phosphorus content.
