DRY MATTER AND NITROGEN CHANGES IN FIVE TROPICAL GRASSES AS INFLUENCED BY CUTTING HEIGHT AND FREQUENCY
Queensland Department of Primary Industries, South Johnstone, Qld. 4859
A clipping experiment to examine the effect of cutting height and frequency on dry matter yield and nitrogen concentration of five tropical grasses was carried out (1973–75) in a high rainfall, humid environment at South Johnstone in north-eastern Queensland. The grasses examined were common and Makueni guinea (Panicum maximum), setaria (Setaria sphacelata var. splendida), Basilisk signal grass (Brachiaria decumbens) and pangola grass (Digitaria decumbens). Cutting frequencies were 3, 6 and 12 weeks with cutting heights of 5, 10 and 15 cm (stoloniferous 1 grasses) and 10, 20 and 30 cm (tufted grasses) in 1973–74 and 5, 10 and 20 cm for all grasses in 1974–75.
