Which oat varieties performed best for hay production at Kimba in 2018? locations
Aims

Farmers in the Kimba area have been producing oaten hay for export for several years. The industry has been expanding, with dedicated storage facilities established in recent years on the outskirts of Kimba. To maximise production and quality, the Buckleboo Farm Improvement Group wanted to identify the current best oaten hay variety for the Kimba area.

Key messages
  • All oat varieties tested at Kimba in 2018 produced the same dry matter, hay quality and grain yield.
  • Durack was the earliest maturing variety (for potential hay cutting and grain), so a good choice in very dry seasons.
  • In a dry season Moby barley performed well for early dry matter production compared to oats, but performed poorly for grain yield.

Kimba (Cliff) 2018

Sow rate or Target density Seeding rates for every variety were targeted to an establishment of 180 plants/m2
Sowing machinery

Seed for seven oat varieties and one grazing barley variety were supplied by Balco. The trial was sown with SARDI small plot equipment on 4 May into moist seed bed conditions (wet to 10 cm only) with 60 kg/ha of DAP fertiliser (18:20:0:0). Seeding rates for every variety were targeted to an establishment of 180 plants/m2. Due to no weeds being present, no pre-emergent herbicides were applied to the trial site.

 

Plant establishment was counted on 20 June, with dry matter cuts taken on 12 July, 22 August, 31 August and 18 September. Plant height was measured on 18 September. Dry matter samples, simulating hay production, from 18 September (except Durack, 31 August) were dried for 48 hours at 40oC and sent for feed quality analysis using FeedTest. The trial was harvested on 8 November.
