Fig. 3. Weanling bull liveweight gain per hectare response to stocking rate (SR) on stargrass pastures fertilized at three rates of N. For N rates of 112, 224, and 336 kg N ha–1, respectively, fitted curves for Year 1 are Y = –78 + 305 SR – 30.8 SR2; Y = –462 + 499 SR – 49 SR2; and Y = –160 + 359 SR – 33.5 SR2. For N rates of 112, 224, and 336 kg N ha–1, respectively, fitted curves for Year 2 are Y = –26 + 242 SR – 20.8 SR2; Y = –488 + 501 SR – 46.7 SR2; and Y = –158 + 283 SR – 19 SR2.
