Abstract
Two experiments were carried out on a seasonally flooded clay soil at Beatrice Hill Experimental Station, Northern Territory, to investigate the response of Para grass to different level of N and P fertilization, and to different types and method of application of fertilizer, in a situation where the grass is used as a saved fodder for the dry season. It was shown that P fertilization of Para grass, on these soils did not give a responses in dry matter yield. Nitrogen fertilization gave increased yields but the greatest return in terms of dry matter yield was at the lower increments of fertilization. Crude protein content was also increased by N fertilization but only at very high rates of N. The type of nitrogen fertilization and method of application had smaller effects on yields than did the level of fertilization but deep placement of ammonium fertilizers did show some yield differences over surface application.
