This study aimed to evaluate the effect of sulfur levels as additive in the production, chemical composition and digestibility of hydroponic green fodder barley. Four levels of S were used: 0, 20, 30 and 40 ppm and harvest was done at 18 days. A completely random design was used with five repetitions. Biomass production (PB) and the height of stem (AT) were 34.9±0.5 kg/m2 and 14.61±1.38 cm, respectively, having a lineal response for PB (Y=5.33+0.67X) and AT (Y=10.10+1.80X). The 0 S level showed higher crude protein (CP) content and nitrogen-free extract: 12.95±4.21% and 55.19±3.95% respectively; the 30 ppm level showed higher content of crude fibre (CF) to the raw fiber and neutral detergent fiber (NDF): 23.61±3.65% and 65.95±4.15% respectively; and the 40 ppm level showed higher content of ether extract (EE) and ash: 3.88±3.15% and 4.61±2.98%, respectively. The apparent digestibility of CF and EE were significantly affected by sulfur levels.
