The water use characteristics and nutritive value of rhodes grass (cv. Katambora) and forage maize (cv. Sharquiah White) under sprinkler irrigation were compared in experiments conducted at Sultan Qaboos University Experimental Station during 1996 to 1998. The soil type was sandy loam (coarse-silty, mixed hyperthermic, Torriarents). Irrigation scheduling was based on SCS-Microcomputer Irrigation Package, with catch cans being used to measure the amount of water applied by the irrigation system. Water use efficiency (WUE) values and dry matter (DM) yield for forage maize were 2.24 kg/m3 and 1.54 kg/m2, respectively. The corresponding values for rhodes grass were 0.91 kg/m3 and 1.00 kg/m2. Forage maize had significantly lower crude fibre (CF), neutral detergent fibre (NDF), acid detergent fibre (ADF), and higher total non-structural carbohydrate (TNC) concentrations than rhodes grass. There were no significant differences in crude protein concentration. These results clearly show that forage maize was superior to rhodes grass with respect to water use efficiency as well as nutritive value at the South Batinah Region of Oman.
