Issue EP farmers identified as a problem with stubble retained systems was sowing into non-wetting sands and the resulting uneven germination. The trial at Murlong (near Lock) was established in 2013 to compare how crop establishment is affected by time of sowing, sowing rate, and seed position and depth on a non-wetting sand.

Pre sowing chemical applications were Roundup Powermax @ 1.5 L/ha, Avadex @ 1.5 L/ha and trifluralin @ 1.5 L/ha applied before each sowing. Broad-leaved control was applied using Amicide Advance@ 1.2 L/ha and Lontrel @ 100 ml/ha on 17 June (TOS 1), 14 July (TOS 2) and 25 August (TOS 3), respectively. |

On 25 August 500 ml/ha of propiconazole was applied over the whole trial for spot form of net blotch. |
