Table (3) Fresh, dry weight and chemical composition of Diplachne fusca grown in salt affected soil at the south coast of Qaroan Lack. Character Value Character Value Fresh weight (ton acre -1 /year) 8.2 Phosphorus % 0.16 Dry weight (ton acre -1 /year) 3.2 Calcium % 0.54 Crude protein % 9.2 Magnesium % 0.40 Crude fibre % 31.4 Potassium % 1.02 Crude fat % 1.83 Sodium % 2.14 Soluble carbohydrate % 42.9 K/Na ratio 0.48 Ash % 14.7 Therefore, Diplachne fusca seemed to be promising forage crops as well as to overcome the desertification problems particularly in arid and semi arid regions of Egypt.
