Description
Four tropical grasses and one legume were grown on an oxic dystropept soil in W. Java, Indonesia. Two levels of S fertilizer were applied (0 and 60 kg S/ha). Forages were harvested at 6 and 9 week intervals during the wet and dry monsoons respectively. Production of leaves and stems was determined separately and samples of a 6- and 9-week regrowth were analyzed for chemical composition. The effect of S fertilization on dry matter (DM) yield was markedly influenced by the effect of season. During the wet season only the production of stems from napier grass was increased (P < .05). During the dry season stem and leaf production of napier grass and centro increased (P < .05) under fertilization but there was a decrease (P < .05) in leaf production of guinea grass. S fertilization increased S content in leaves and stems by 23%. There was a tendency for N to increase and for NDF in leaves to decrease. Only in centro was ADF and lignin of fertilized plants lower (P < .05). Although Ca, P, Mg, Cu and Zn were not affected by fertilization, ash content in leaves of fertilized forages differed (P < .05) from controls.
