Tropical grass pennisetum glaucum were grown in five levels of sulphur (0, 2.5, 5.0, 7.5, 10.0 ppm) in sand culture arranged in a randomized complete block design to determine the effect of sulphur doses on the quality of the grass. Quality parameters accessed were dry matter (DM), selected mineral composition (P, Ca, Mg, & Mn), carotene, soluble carbohydrate, crude protein (CP), digestibility of CP (DCP) and chlorophyll content. Dry matter production increased with S-supply with 2.5 ppm and 10.0 ppm, producing about 2.3 times and 1.3 times at 3rd and 4th clipping respectively over the control grasses. Magnesium content increased with S-levels, while P, Ca and Mn were higher in the culture g
