Pasture cropping with tropical grasses has shown promise for several regions in the WA wheat belt. In this research, we modelled the crop yield, pasture yield, and total production for barley and canola crops grown either as monocultures or with kikuyu or Gatton panic, for 5 location in WA. Pasture suppression efficacy was modelled at either 90 or 98%. Kikuyu was particularly competitive, and appears less suitable for pasture cropping than Gatton panic. For barley sown into Gatton panic pasture, yield penalties were generally small, but results were more variable for canola.
