Early seeding was the key to producing optimal grain quality, high grain yield and maximum return per hectare from oat grain production in our seed rate trials in lower rainfall areas in 2015. When sowing was delayed from early May to early June grain yield reduced by 32% and this was reflected in a 45% reduction in returns per hectare and a higher proportion of Oat2 quality grain produced. Variety choice and seeding date had a larger impact on what grade of oat was produced than plant density (Figures 3, 4, 5 and 6). Plant density did influence hectolitre weight and screenings, but the effects were generally small and often not large enough to change the grade. Carrolup was the poorest performing variety in this study. Although Williams performed well in this study as a high yielding oat variety, its tendency for low hectolitre weight and high screenings, which is consistent with the observations of Troup et al. (2015), suggests tha |

Trials were established into canola stubble and were direct-drilled with a small plot air-seeder with on-row packing press wheels. |
Sow date | 8 May 2015 First week of May and first week of June. |

Fertiliser |
An NPK compound fertiliser was banded below the seed at 180 kg/ha, with 43 kg/ha of urea top-dressed in front of the bar, supplying a total of 40 kg N/ha, 25 kg P/ha and 9 kg K/ha. |
Seed treatment | Seed was treated with Vibrance and Emerge at label rate. |
