Sowing machinery |
The fluid fertiliser delivery system placed fluid fertiliser approximately 3 cm below the seed at an output rate of 100 L/ha. The fungicide fluid system could also be split to deliver fluids both below the seed at approximately 3 cm, and above in the seeder furrow behind the press wheel in a 1 cm band. |

Fertiliser |
The control treatment was 60 kg/ha of Mace wheat with 50 kg/ha of 18:20:0:0 (DAP). Urea was spread over the whole trial on 31 July at 20 kg/ha. All phosphorus treatments were applied to the same rate of 9 units of phosphorus (P) and balanced with urea or UAN to 10 units of nitrogen (N). Manganese (Mn) was selected as the main focus trace element, with zinc (Zn) and copper (Cu) also included in the trace element mix. A DAP fertiliser dry blend with Mn @ 1.5 kg/ha was sourced. Phosphoric acid and granular urea, and ammonium poly phosphate (APP) and urea ammonium nitrate (UAN) were used as fluid fertiliser products to compare with granular fertilisers. Manganese sulphate was dissolved with standard rate being 1.5 kg/ha and 3 kg/ha as a high rate. 1 kg/ha Zn, as zinc sulphate and 0.2 Cu of copper sulphate were dissolved in the standard rates of trace elements, which were also delivered as foliar applications at 4-5 leaf stage. |
Herbicide |
pre-sowing weed control of 1.5 L/ha Roundup Attack, 1.5 L Boxer Gold and 80 ml/ha Nail. In crop weed control was on 31 July with 1.2 L/ha of Broadside, later than ideal due to the sampling required on the trial. |
Fungicide |
The fungicides Uniform, EverGol, Vibrance (seed dressing) were assessed for Rhizoctonia disease suppression at different rates and in split applications. Triadimefon was also applied on fertiliser as a treatment. |
