Fertiliser |
For the Blackleg trial the fertiliser treatment was 100 kg/ha of 18:20:0:0 with in furrow fungicides or trace elements delivered as a fluid. The trace element treatment had Mn at 1.5 kg/ha of manganese sulphate, 1 kg/ha Zn as zinc sulphate and 0.2 kg/ha Cu as copper delivered at a water rate of 80 L/ha. The paddock was spread with 500 kg/ha of gypsum in mid-April. 90 kg/ha of urea was applied broad acre on 25 June and also on 13 July. The Mn trial was not harvested because of very poor establishment, a dry finish and extensive bird damage near maturity which made fair comparisons between treatments impossible. Only results from the Coulta Blackleg trial are reported. |

Herbicide |
The paddock was sprayed with 2.5 L/ha Roundup Attack with 2% LI700, 1.5 L/ha TriflurX, 100 ml/ha Goal, 40 g/ha Sentry and 290 ml/ha Lorsban with an 80 L/ha water rate. Weed control was applied broad acre on 20 June with Targa @ 500 ml and Select @ 500 ml with 5% uptake at 100 L/ha water rate. The fungicide trial was desiccated on 2 November with Sprayseed 250 @ 4 L/ha and harvested on 16 November 2015. |
