40 kg/ha DAP was used as the control rate of fertiliser, this equals 8 units of phosphorus and 7.2 units of nitrogen (8P, 7.2N) |

1.5 L/ha Gramoxone, 1 L/ha trifluralin and 60 ml/ha Striker at sowing, then 2 L/ha Sprayseed, 1 L/ha Alpha Cypermethrin just before the trial emerged. On 1 July 2013 the trial was sprayed for broadleaved weed control using 750 ml/ha Intervix, 400 ml/ha Agritone750 and 500 ml/100L SuperCharge. |
