Crop establishment on non-wetting soil locations
Aims

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.

Key messages
  • Deeper sowing at 3-4 cm achieved better early dry matter and increased grain yield in a later sowing.
  • Frost damage may have lowered yield with early sowing, but inter-row placement at TOS1 had the highest yield.
  • TOS 3 placement in row achieved better early plant growth and higher grain yield.
  • Later sowing reduced brome grass numbers, and the size of the panicles, so it substantially lowered returns to the seed bank.

Herbicide

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.

Insecticide

Nil

Fungicide

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