Abstract

Growth of cattle was measured between Annual liveweight gain of steers at the low stocking 1974-75 and 1980-81 on a white clover (Trifolium rate (1.67lha) without superphosphate declined from repens) and carpet grass (Axonopus affinis) pasture 165 kglsteer in year 1 to 38 kglsteer in year 7, receiving superphosphate applied at 0, 12, 24, and while 24 kg P/ha maintained liveweight gain at 48 kg P/ha annually. Hereford weaner steers grazed the 120-220 kglsteer. Annual liveweight gain was negatively pastures at 1.67, 2.5, and 3.3 steersha. Linear responses related to stocking rate, averaging -31.3 kglsteer for each to superphosphate and stocking rate were significant increment in stocking rate. Calculated stocking rates (P
