Sowing machinery |
In the 2014, 2015 and 2016 seasons, three replicated trials were established (total of 9 trials), at Warramboo on a red sandy soil and two at Streaky Bay on a grey calcareous sand. Both sites had nutrition delivery treatments and fungicide application strategies. The fluid fertiliser delivery system placed fluid fertiliser approximately 3 cm below the seed at an output rate of 100 L/ha. The fluid system could also split the fluids to deliver the fungicide both below the seed at approximately 3 cm, and in the seeder furrow behind the press wheel in a band approximately 1 cm in width. |

Fertiliser |
The control was 60 kg/ha of Mace wheat with 50 kg/ha of 18:20:0:0 (DAP). All phosphorus treatments were applied to the same rate of 9 kg/ha of phosphorus (P) and balanced with urea or UAN to 10 kg/ha of nitrogen (N). Manganese (Mn) was selected as the main focus trace element and a DAP fertiliser dry blend with Mn @ 1.5 kg/ha was used. Phosphoric acid and granular urea, or ammonium nitrate (UAN) were used as fluid fertiliser products to compare with granular fertilisers. Manganese sulphate was dissolved with the standard rate being 1.5 kg Mn/ha and 3 kg/ha as a high rate. 1 kg/ha Zn, as zinc sulphate and 0.2 kg/ha Cu as copper sulphate were dissolved in the standard rates of trace elements, which were also delivered as foliar applications at 4-5 leaf stage. The extra nitrogen at seeding treatment was applied as 40 kg/ha of granular urea. |
Fungicide |
The fungicides azoxystrobin + metalaxyl-M (Uniform), penflufen (EverGol Prime, and new formulation of EverGol Prime for fluid delivery in 2016) and sedaxane (Vibrance seed dressing) were assessed for Rhizoctonia disease suppression at different rates and in split applications. Triadimenol and flutriafol were also applied on fertiliser as treatments. |
